Abstract
Wood-inhabiting fungi are key decomposers in forest ecosystems, but the diversity of corticioid fungi in the Qinling Mountains remains insufficiently explored. During surveys of macrofungi in Zhashui County and Shangzhou District in the Qinling Mountains, several specimens representing three undescribed taxa of corticioid fungi were collected. Based on detailed morphological examinations and phylogenetic analyses of combined ITS+nLSU datasets by using Maximum Likelihood and Bayesian Inference methods, three new species, viz. Hymenochaete zhashuiensis, Hyphoderma brevicystidiatum and Steccherinum shangzhouense, are described and illustrated. Hymenochaete zhashuiensis is characterized by effused-reflexed basidiomata with a reddish to rust-brown, cracked hymenial surface, abundant dark brown hymenial setae, the presence of dendrohyphidia, and ellipsoid to broadly ellipsoid basidiospores (4–5.6 × 2.8–3.5 µm). Hyphoderma brevicystidiatum is distinguished by resupinate, basidiomata white to cream with hymenial surface, clamped generative hyphae, short cylindrical to subcylindrical cystidia, subclavate to clavate basidia, and ellipsoid to subcylindrical basidiospores (6.2–10 × 2.7–4.2 µm). Steccherinum shangzhouense is characterized by resupinate and membranaceous basidiomata, a white to cream, tuberculate to slightly grandinioid and cracked hymenial surface, simple-septate generative hyphae, the absence of cystidia and skeletocystidia, and broadly ellipsoid to oblong ellipsoid basidiospores (5.2–7.9 × 2.5–5 µm). These findings enrich the wood-inhabiting fungal diversity in the Qinling Mountains and indicate that this region remains underexplored for wood-inhabiting fungi.

Introduction
Wood-inhabiting fungi are a group of macrofungi primarily composed of polyporoid and corticioid fungi, in which they play a crucial role as decomposers in forest ecosystems, driving wood degradation and the recycling of organic matter (Dong et al. 2024). Among them, polypore fungi usually produce poroid basidiomata and have been well investigated in China (Wu et al. 2022; Xu et al. 2025). While corticioid fungi usually produce resupinate or effused-reflexed basidiomata, their inconspicuous basidiomata often cause these fungi to be overlooked in biodiversity surveys, and 1400 species have been reported in China (Dai et al. 2004b; Yuan et al. 2026). During surveys of macrofungi in Zhashui County and Shangzhou District of the Qinling Mountains, we collected several corticioid fungal specimens that cannot be assigned to any known species. Preliminary morphological observations indicate that these specimens belong to the genera Hymenochaete Lév., Hyphoderma Wallr. and Steccherinum Gray.
The genus Hymenochaete was established by Léveillé (1846), with H. rubiginosa (Dicks.) Lév. as the type species and belongs to Hymenochaetaceae Donk, Hymenochaetales Oberw. (Dai 2010; He and Dai 2012; Parmasto et al. 2014; Liu et al. 2025). The genus exhibits annual to perennial, resupinate, effused-reflexed, pileate or stipitate basidiomata, brownish to reddish brown hymenial surface, monomitic or dimitic hyphal system, simple-septate generative hyphae, hymenial setae or other setal elements, and hyaline to brownish, thin- to thick-walled basidiospores (Parmasto 2001; He and Dai 2012; Liu et al. 2025). Traditional classification discriminated species or sections mainly based on basidiomatal structure and the presence or absence of layers such as the setal layer, context or subiculum, and cortex (Burt 1918; Léger 1998). However, molecular phylogenetic studies have shown that morphological characters alone are insufficient to delimit species within this genus (Wagner and Fischer 2002; Parmasto et al. 2014; Liu et al. 2025). Subsequent molecular phylogenetic studies have clarified the phylogenetic relationships of Hymenochaete and related non-poroid Hymenochaetaceae and revealed extensive cryptic diversity worldwide (Parmasto et al. 2014; Liu et al. 2025; Wang et al. 2026). In China, some species of Hymenochaete have been described based on morphological characteristics and molecular phylogenetic evidence (Dai 2010; He and Dai 2012; He et al. 2017; Liu et al. 2025; Wang et al. 2026). To date, the genus Hymenochaete comprises approximately 265 recognized species, of which 120 have been recorded in China (Liu et al. 2025; Zhao et al. 2025; Wang et al. 2026; Xu et al. 2026; Zhu et al. 2026).
The genus Hyphoderma was established by Wallroth (1833), with H. setigerum (Fr.) Donk as the type species and belongs to Hyphodermataceae Jülich, Polyporales Gäum. (Donk 1957; Larsson 2007; Justo et al. 2017; Li et al. 2026; Yang et al. 2025). The genus exhibits considerable macromorphological diversity, with resupinate to effused-reflexed, ceraceous to membranaceous basidiomata, smooth, tuberculate, grandinioid or odontioid hymenophore, monomitic to dimitic hyphal system with clamped generative hyphae, suburniform to subcylindrical or clavate basidia, and ellipsoid to subglobose basidiospores (Bernicchia and Gorjón 2010; Guan et al. 2021; Duan et al. 2023; Yang et al. 2023). Taxonomically, the generic delimitation of Hyphoderma and its related genera has long been controversial. Traditional classification included a broad assemblage of corticioid fungi in Hyphoderma, but subsequent molecular phylogenetic studies demonstrated that the traditionally circumscribed genus was polyphyletic, leading to the transfer of several species to related genera such as Peniophorella P. Karst. (Larsson 2007; Justo et al. 2017; Li et al. 2026). Subsequent molecular phylogenetic studies have refined the circumscription of Hyphoderma and confirmed the independent phylogenetic position of the core Hyphoderma lineage within Hyphodermataceae (Justo et al. 2017; Yang et al. 2023, 2025; Li et al. 2026). In recent years, multiple new species of Hyphoderma have been described in China based on morphological characteristics and molecular phylogenetic evidence (Guan and Zhao 2021a, 2021b; Ma et al. 2021; Yang et al. 2023, 2025; Su et al. 2024). Currently, the genus Hyphoderma comprises approximately 132 species, of which 54 species are distributed in China (Guan et al. 2021; Li et al. 2026; Yuan et al. 2026).
The genus Steccherinum was established by Gray (1821), with S. ochraceum (Pers.) Gray as the type species and belongs to Steccherinaceae Parmasto, Polyporales (Zhang et al. 2025; Westphalen et al. 2026). The genus exhibits resupinate to effused-reflexed or pileate basidiomata with membranaceous to corky or waxy, and odontioid, hydnoid, grandinioid or poroid hymenophore, monomitic to dimitic hyphal system, thick-walled and encrusted skeletocystidia, and ellipsoid to subglobose basidiospores (Ryvarden 1991; Westphalen et al. 2021, 2026). Taxonomically, the generic delimitation between Steccherinum and its closely related genus Junghuhnia Corda has long been controversial (Westphalen et al. 2018). Traditional classification discriminates these two genera mainly based on hymenophoral morphology, with Junghuhnia characterized by a poroid hymenophore and Steccherinum by an odontioid hymenophore (Du et al. 2020). Subsequent molecular phylogenetic studies have verified that Steccherinum comprised both poroid and odontioid species, further clarifying its independent phylogenetic position within the family Steccherinaceae (Miettinen et al. 2012; Justo et al. 2017; Yuan et al. 2019; Westphalen et al. 2021, 2026). Recently, multiple new Steccherinum species have been described based on morphological characteristics and molecular phylogenetic evidence in China (Dong et al. 2022, 2023; Liu et al. 2023b; Wang et al. 2024; Zhang et al. 2025). The genus Steccherinum currently comprises 91 accepted species worldwide, and 29 Steccherinum taxa have been published or recorded from China (Yuan and Wu 2012; Liu and Dai 2021; Dong et al. 2022; Yuan et al. 2026).
To further clarify the taxonomic status of these specimens, species identifications were performed based on detailed morphological observations and phylogenetic analyses of the combined ITS+nLSU dataset. The results indicate that these specimens represent three new species belonging to Hymenochaete, Hyphoderma, and Steccherinum, respectively.
Materials and methods
Morphological studies
Fresh specimens of Hymenochaete, Hyphoderma and Steccherinum were collected from Zhashui County and Shangzhou District, Shaanxi Province, China. The basidiomata were photographed in situ, and macromorphological characters, substrates and habitats were recorded in the field. The specimens were dried and deposited at the herbarium of the Institute of Microbiology, Beijing Forestry University (BJFC), Beijing, China. Color terms used in macromorphological descriptions follow Kornerup and Wanscher (1967).
Macromorphological descriptions were based on field notes and laboratory observations. Micromorphological characters, measurements and drawings were made from slide preparations mounted in 5% potassium hydroxide (KOH), Cotton Blue (CB) and Melzer’s reagent (IKI), using a Nikon Eclipse 80i microscope (Nikon, Tokyo, Japan). At least 30 basidiospores were measured from each specimen. Sterigmata were excluded from basidial measurements, and the hilar appendage was excluded from basidiospore measurements. The following abbreviations are used: CB = Cotton Blue, CB– = acyanophilous, IKI = Melzer’s reagent, IKI– = neither amyloid nor dextrinoid, KOH = 5% potassium hydroxide, L = mean basidiospore length, W = mean basidiospore width, Q = range of the length/width ratio of basidiospores, Qm = mean length/width ratio of basidiospores, and n = a/b, where a represents the number of measured structures and b represents the number of specimens examined. When sufficient measurements were available, 5% of measurements were excluded from each end of the range and are given in parentheses. The detailed morphological methods followed Sun et al. (2022) and Liu et al. (2023a).
DNA extraction and sequencing
Genomic DNA was extracted from dried specimens using the CTAB rapid plant genome DNA extraction kit DN14 (Aidlab Biotechnologies, Beijing, China), following the manufacturer’s instructions with modifications as described by Song et al. (2025). The internal transcribed spacer region (ITS) was amplified with primers ITS5 and ITS4 (White et al. 1990), and the nuclear large subunit ribosomal RNA gene region (nLSU) was amplified with primers LR0R and LR7 (Hopple Jr and Vilgalys 1999).
The polymerase chain reaction (PCR) program for ITS consisted of an initial denaturation at 95 °C for 3 min, followed by 35 cycles at 94 °C for 40 s, 56 °C for 45 s and 72 °C for 1 min, and a final extension at 72 °C for 10 min. The PCR program for nLSU consisted of an initial denaturation at 94 °C for 1 min, followed by 35 cycles at 94 °C for 30 s, 50 °C for 1 min and 72 °C for 90 s, and a final extension at 72 °C for 10 min. PCR products were sequenced at the Beijing Genomics Institute (BGI), China, using the same primers.
The newly generated sequences were assembled and edited, and then deposited in GenBank. All newly generated sequences and reference sequences used in the phylogenetic analyses are listed in Table 1.

Phylogenetic analysis
Phylogenetic analyses were conducted separately for Hymenochaete, Hyphoderma and Steccherinum based on the combined ITS+nLSU datasets. Reference sequences were retrieved from GenBank (Table 1). In the phylogenetic analyses, Hydnoporia olivacea (Schwein.) Teixeira was selected as the outgroup for Hymenochaete (Miettinen et al. 2019), Diplomitoporus crustulinus (Bres.) Domański was selected as the outgroup for Hyphoderma (Justo et al. 2017), and Cabalodontia delicata Westph. & Motato-Vásq. was selected as the outgroup for Steccherinum (Westphalen et al. 2021).
Sequence alignments were generated using MAFFT v.7 (Katoh et al. 2019) and manually adjusted in BioEdit v.7.0.9 (Hall 1999). Gaps were treated as missing data. The ITS and nLSU alignments were concatenated using Mesquite v.3.2 (Maddison and Maddison 2017).
Maximum Likelihood (ML) analysis was performed using RAxML-HPC2 v.8.2.3 (Stamatakis 2014). The best-scoring ML tree was searched under the GTRGAMMA model, and branch support was assessed with 1000 rapid bootstrap replicates. Bayesian Inference (BI) was performed using MrBayes v.3.2.6 (Ronquist et al. 2012). The substitution model was set to GTR + I + G, with six substitution types and gamma-distributed rate variation across sites with a proportion of invariable sites (nst = 6, rates = invgamma). Base frequencies were assigned a Dirichlet prior. Five Markov Chain Monte Carlo (MCMC) chains were run for 50 million generations, with trees sampled every 100 generations. The temperature parameter was set to 0.2, and the analysis was allowed to stop when the average standard deviation of split frequencies fell below 0.01 (Ronquist and Huelsenbeck 2003). The first 25% of sampled trees were discarded as burn-in, and the remaining trees were used to generate a 50% majority-rule consensus tree and calculate Bayesian posterior probabilities (BPP).
Phylogenetic trees were visualized using FigTree v.1.4.4 (Rambaut 2018). The ML topology is presented, with ML bootstrap values and Bayesian posterior probabilities indicated at the nodes. Only ML-BS ≥ 75% and BPP ≥ 0.90 are shown. Nodes with ML-BS ≥ 75% and BPP ≥ 0.95 were considered well supported.
Results
Phylogenetic analyses
To clarify the phylogenetic positions of the newly collected specimens, three independent phylogenetic analyses were conducted for Hymenochaete, Hyphoderma and Steccherinum based on combined ITS+nLSU datasets.
The combined ITS+nLSU dataset for Hymenochaete comprised sequences from 225 fungal samples representing 139 species of Hymenochaete and the outgroup species Hydnoporia olivacea. The aligned matrix was 2622 characters in length, including 1115 constant characters, 750 parsimony-uninformative variable characters and 757 parsimony-informative characters. Phylogeny results indicated that specimen Cui 24846 formed a distinct lineage (100% ML, 1.00 BPP; Fig. 1), and exhibited a close phylogenetic affinity to Hymenochaete tasmanica Massee (Fig. 1).

The combined two-gene dataset (ITS+nLSU) for Hyphoderma comprised sequences from 91 fungal samples, representing 56 species of Hyphoderma and the outgroup species Diplomitoporus crustulinus. The aligned matrix was 2072 characters in length, of which 1356 were constant, 164 were parsimony-uninformative variable characters and 552 were parsimony-informative. Phylogenetic analyses revealed that specimens Cui 24841 and Cui 24844 formed a well-supported independent clade (98% ML, 0.99 BPP; Fig. 2) and showed a close phylogenetic relationship with Hyphoderma setigerum (Fig. 2). Independent BLAST searches of the ITS and nLSU sequences of Cui 24841 and Cui 24844 were conducted against the NCBI nucleotide database. After exclusion of the query sequence itself, neither gene region yielded close matches to any validly named Hyphoderma species. For ITS sequences, the 20 highest-scoring non-self-hits were assigned to H. subsetigerum Sheng H. Wu, with sequence identities ranging from 97.15% to 98.83%. For the nLSU sequences, the closest non-self matches included H. floccosum C.L. Zhao & Q.X. Guan, H. guangdongense J.Q. Su & C.L. Zhao, H. nudicephalum Gilb. & M. Blackw., H. pinicola Yurchenko & Sheng H. Wu, H. setigerum, H. sordidum Yang Yang & C.L. Zhao, H. subsetigerum and H. tenuissimum C.L. Zhao & Q.X. Guan, with sequence identities ranging from 97.88% to 99.88% (Table 2).

Discussion
In recent years, numerous new species of wood-inhabiting fungi reported from China have been concentrated in South and Southwest regions (Dai et al. 2004a, 2007, 2009; Yuan and Dai 2008; Zhao et al. 2015; Wu et al. 2016, 2021a, 2021b; Zhang et al. 2023; Zhou et al. 2023), whereas research on the species diversity of corticioid fungi in the Qinling Mountains remains limited. In this study, three new species belonging to the genera Hymenochaete, Hyphoderma and Steccherinum were identified in Zhashui County and Shangzhou District in the eastern Qinling Mountains.
Phylogenetic analysis of Hymenochaete revealed that Cui 24846 clustered with H. tasmanica, forming a well-supported clade (100% ML, 1.00 BPP; Fig. 1). Morphologically, H. tasmanica is similar to H. zhashuiensis by sharing a monomitic hyphal system with simple-septate generative hyphae. However, H. tasmanica differs by having thinner basidiomata (200–800 µm thick), a smooth to slightly tuberculate and usually uncracked hymenial surface, the presence of a cortex, reddish brown setae, larger basidia (19–25 × 3.5–4.5 µm), and slightly narrower basidiospores (4–5.5 × 2.5–3 µm; He and Li 2012). Hymenochaete ochromarginata P.H.B. Talbot and H. rubiginosa (Dicks.) Lév. also produce effused-reflexed basidiomata and abundant hymenial setae, but H. ochromarginata differs from H. zhashuiensis by its yellowish brown to brown pileus with concentrically zonate and sulcate, yellow to ochraceous hymenial margin, shorter hymenial setae (20–56 × 5–10 µm), smaller basidiospores (2–4 × 1.6–2 µm; Vinjusha and Kumar 2024); H. rubiginosa differs from H. zhashuiensis by its perennial, woody hard basidiomata with distinct cortex, subdimitic hyphal system with sclerefied hyphae, usually uncracked hymenium, and narrower, elongate-ellipsoid basidiospores (3.5–5.5 × 2–3 µm; Corfixen and Parmasto 2017). Hymenochaete erastii S.H. He et al. and H. zhashuiensis share the presence of a hyphal layer and setal layer and the absence of a cortex, but the former differs by its strictly resupinate, closely adnate basidiomata, grayish violet to clay buff hymenial surface, crystalline masses in the setal layer, smaller setae (30–46 × 3–7 µm), and narrower oblong-ellipsoid to cylindrical basidiospores (4–5 × 1.7–2 µm; Liu et al. 2025).
In the phylogenetic analyses based on combined ITS and nLSU sequences, two specimens of Hyphoderma brevicystidiatum (Cui 24841 and Cui 24844) formed an independent lineage with strong nodal support (98% ML, 0.99 BPP; Fig. 2). This species clustered together with H. alboarachnum Wen Li & C.L. Zhao, H. floccosum, H. guangdongense, H. paramacaronesicum Tellería et al., H. pinicola and H. setigerum, constituting a highly supported clade (Fig. 2). Morphologically, all these species possess resupinate basidiomata and a monomitic hyphal system bearing clamp connections. Nevertheless, compared to Hyphoderma brevicystidiatum, H. alboarachnum differs by its arachnoid hymenial surface, absence of cystidia and cystidioles, cylindrical basidia (23.5–30 × 3.5–4.5 µm), and smaller basidiospores (5–6 × 2–3 µm; Li et al. 2026); H. floccosum is distinguished by its farinaceous hymenial surface, two types of cystidia, including thick-walled and abundantly encrusted cystidia (60–161 × 5.5–10 µm) and tubular, thin-walled cystidia (37.5–100 × 4–8.5 µm; Guan and Zhao 2021b); H. guangdongense differs by its farinaceous basidiomata, thicker generative hyphae (3.5–6.0 µm), two types of cystidia, including septate cystidia (93–144 × 8–10.4 µm) and tubular cystidia (55–63 × 6.5–10.3 µm), and cylindrical basidiospores (7.4–9 × 3.2–4 µm; Su et al. 2024); H. paramacaronesicum is readily distinguished by its yellowish white to pale orange-yellow basidiomata, cylindrical leptocystidia with several constrictions (70–124 × 8–13 µm), larger basidia (40–48 × 6–9 µm), and larger, ellipsoid basidiospores (12–15 × 5.5–7 µm; Martín et al. 2018); H. pinicola differs by its chalky white, minutely warted to porulose hymenial surface, larger basidia (25–28 × 5–6.5 µm), longer septocystidia (65–180 µm long), and longer, cylindrical to allantoid basidiospores (13–16 × 4–4.5 µm), as well as its occurrence on dead wood of Pinus in Yunnan Province (Yurchenko and Wu 2014a); H. setigerum differs in thick-walled and encrusted cystidia (120–180 × 7.5–10 µm), larger basidia (25–40 × 6.5–7 µm), and subcylindrical basidiospores (9.5–11.5 × 3.5–4.5 µm; Nilsson et al. 2003). Furthermore, additional comparisons were made with four members or closely related segregates of the Hyphoderma setigerum complex. Hyphoderma subsetigerum differs from H. brevicystidiatum in having a grandinioid hymenophore with a whitish to ivory-yellow hymenial surface, thick-walled generative hyphae, narrower basidia (20–30 × 4.5–5.5 µm), and smaller basidiospores (6–8 × 2.8–3.2 µm; Wu 1997); H. bisetigerum is distinguished by predominantly two-sterigmate basidia and thick-walled, heavily encrusted septocystidia, whereas H. brevicystidiatum has four-sterigmate basidia and short, mostly smooth cystidia with only occasional crystalline deposits (Boidin and Gilles 2003); H. nudicephalum differs in its farinaceous to odontioid hymenial surface, thick-walled generative hyphae, and conspicuous capitate cystidia with swollen, non-encrusted apices (Gilbertson and Blackwell 1988); H. tenuissimum is separated from the new species by its tuberculate to minutely grandinioid, slightly buff hymenial surface, thick-walled generative hyphae, and much longer cylindrical cystidia with 4–12 clamped septa and abundant encrustations (50–220 × 6.5–13 µm), and larger, cylindrical basidiospores (7–10.5 × 3–4.5 µm; Guan et al. 2021).
In the phylogenetic tree of the genus Steccherinum, specimens of S. shangzhouense (Cui 24842, Cui 24843 and Cui 24845) formed a distinct independent evolutionary lineage, and clustered with S. fissurutum and S. fragrans to constitute a clade with high statistical support (91% ML, 0.99 BPP; Fig. 3). Nevertheless, these species exhibit conspicuous morphological discrepancies from S. shangzhouense. Specifically, S. fissurutum differs from S. shangzhouense by its subceraceous basidiomata, clamped generative hyphae, presence of numerous strongly encrusted skeletocystidia, and smaller cylindrical basidiospores (4.5–6 × 2.5–3 µm; Dong et al. 2023). Steccherinum fragrans differs by its straw-colored basidiomata with a mild sweet smell, raduloid hymenophore with flattened aculei, pseudodimitic hyphal structure, presence of skeletocystidia, and smaller, broadly ellipsoid, cyanophilous basidiospores (3.5–4 × 2.5–2.8 µm; Crous et al. 2024). During wood-inhabiting corticioid fungi investigations in the Qinling Mountains, we also discovered S. ciliolatum (Berk. & M.A. Curtis) Gilb. & Budington, S. longiaculeiferum J.H. Dong & C.L. Zhao, S. weishanense J.H. Dong & C.L. Zhao and S. straminellum (Bres.) Melo. Compared with S. shangzhouense, S. ciliolatum possesses ceraceous to subceraceous basidiomata, well-developed spines up to 1.5 mm long, dimitic hyphal system with clamped generative hyphae, abundant encrusted cystidia (3.5–8 µm wide), longer basidia (18–22 × 4.5–6 µm), and narrower basidiospores (4.5–5.4 × 1.8–2.7 µm; Maas Geesteranus 1974); S. longiaculeiferum has coriaceous basidiomata, hydnoid hymenial surface with long aculei, dimitic hyphal system with clamped generative hyphae, and smaller, broadly ellipsoid to ellipsoid basidiospores (4–4.3 × 2.5–3 µm; Dong et al. 2024); S. weishanense has coriaceous basidiomata, odontioid hymenial surface with subulate aculei, clamped generative hyphae, two types of cystidia, and smaller ellipsoid basidiospores (4–4.8 × 2.5–3.3 µm; Dong et al. 2024); S. straminellum has an odontioid to hydnoid hymenial surface with spines up to 0.5 mm long, fimbriate margin with hyphal strands, dimitic hyphal system with clamped generative hyphae, frequent encrusted cystidia (7–15 µm wide), and narrower basidiospores (3.5–4.5 × 2–2.2 µm; Ryvarden 2024).
Overall, the present study provides additional evidence that the Qinling Mountains harbor a previously underestimated diversity of wood-inhabiting corticioid fungi. The recognition of three new species, Hymenochaete zhashuiensis, Hyphoderma brevicystidiatum and Steccherinum shangzhouense, is supported by both morphological characters and phylogenetic analyses of the combined ITS+nLSU dataset. Continued surveys in the Qinling Mountains are therefore expected to reveal additional undescribed taxa and will contribute to a more comprehensive understanding of the diversity, taxonomy and biogeography of wood-inhabiting fungi in Qinling Mountains, China.
