Named after its phylogenetic close related to A.gongcheniae.

China, Yunnan Province: Xishuangbanna, Naban River Watershed National Nature Reserve, 21°10'N, 99°55'E, on the stems of unidentified Poaceae plant, Oct 2018, X.X. Feng, YNE01248 (holotype GDMCC 3.1047, stored in a metabolically inactive state); ex-type culture YNE01248.

Asexual morph: Hyphae hyaline, branched, septate, smooth, 1.0–2.5 μm diameter (mean = 1.5 μm, n = 30). Conidia not observed. Chlamydospores single, terminal, globose, rare. Sexual morph: Undetermined.

On PDA, colonies flat, rounded, initially white, becoming yellowish-white, cottony, with moderate aerial mycelia, covering the 90 mm plate after 7 days at 25 °C. On MEA, colonies white, dense aerial mycelia, forming multiple circles around the center, covering the 90 mm plate after 7 days at 25 °C. Conidiomata were not observed.

Phylogenetic analyses confirmed that A.neogongcheniae formed an independent clade, exhibiting a close evolutionary relationship with A.garethjonesii, A.neogarethjonesii and A.subrosea. Based on a BLASTN search of the GenBank database, it was found that A.neogongcheniae shares high similarities with the following strains: A.garethjonesii strain HKAS 96289 (94.88% in ITS, 100% in LSU), strain GZCC 20-0115 (94.88% in ITS, 99.41% in LSU, 96.67% in tef1), strain SICAUCC 22-0027 (94.88% in ITS, 100% in LSU, 96.69% in tub2), strain SICAUCC 22-0028 (94.88% in ITS, 100% in LSU; 96.79% in tub2); A.subrosea strain CGMCC 3.18337 (98.35% in ITS, 99.80% in LSU, 94.61% in tef1, 94.99% in tub2), strain LC7291 (91.41% in ITS, 99.80% in LSU, 94.38% in tef1, 94.99% in tub2); and A.neogarethjonesii strain HKAS 102408 (93.97% in ITS, 100% in LSU). The tef1 and tub2 sequence data are currently unavailable for A.neogarethjonesii to compare with A.neogongcheniae.

Due to the absence of sexual and asexual sporulation characters in A.neogongcheniae, a comparison of its culture characteristics with those of A.garethjonesii, A.neogarethjonesii and A.subrosea was conducted. On PDA, A.neogongcheniae exhibits a yellowish-white surface and reverse color, whereas A.garethjonesii displays a white surface with a reddish reverse, A.neogarethjonesii shows a white to black surface coloration, and A.subrosea presents a light pink surface with a peach-puff reverse. Phylogenetically, A.neogongcheniae strains YNE01248 and YNE01260 form a distinct branch with 99% MLBP and 0.95 BIPP. Therefore, we propose A.neogongcheniae as a novel species.
