1 Taxa synonymised in the present study are noted with a superscript asterisk (*); status of the strains or specimens on which the morphological data is based is noted by superscript ET (ex-epitype), H (holotype) and T (ex-type).

2 UN = unknown, i.e. information not mentioned by the respective authors; the ecological group “potential pathogen” stands for species recovered from symptomatic tissues, but for which pathogenicity tests were not conducted to prove their pathogenicity.

#N/A = not available, i.e. feature not mentioned by the respective authors in the taxonomic description of the species.

Note: several species of the Diaporthe clades treated (including some synonymised in the present study) were excluded from this synopsis due to lack of morphological data regarding their asexual morphs. Some details about their collections are given below.

Diaporthe amygdali clade: D. sterilis Lombard, Polizzi & Crous was introduced by Lombard et al. (2014) as a pathogen on Vaccinium corymbosum in Italy, based on the diagnosis of sequence data, since no sporulation was observed for five different isolates (including the ex-type strain CBS 136969) on different media or on sterilised organic material placed on the media; D. sterilis was synonymised under D. amygdali by Hilário et al. (2021a).

Diaporthe eucommiae clade: D. tuyouyouiae Y.P. Tan, Bishop-Hurley & R.G. Shivas was introduced by Tan & Shivas (2023) from a leaf spot on Decalobanthus peltatus in Queensland (Australia), based on the diagnosis of sequence data obtained apparently from the type specimen (BRIP 75017a), and no taxonomic description was provided. D. xylocarpi M.S. Calabon & E.B.G. Jones (as D. salinicola Dayar.) was introduced by Dayarathne et al. (2020) as a saprophyte on decaying submerged wood of Xylocarpus sp. in Thailand, based on morpho-molecular analyses [the species name was validly published by Calabon et al. (2023)]; however, only the sexual morph was observed on the host tissue, and no sporulation was observed in culture; both species are synonymised here under D. eucommiae.

Diaporthe foeniculina clade: D. parva Y.S. Guo & G.P. Wang was introduced by Guo et al. (2020) as a pathogen on branches with shoot cankers symptoms of Pyrus bretschneideri, based on the diagnosis of sequence data, since the isolates formed globose or irregular, dark brown to black conidiomata-like structure that remained sterile on different media or on sterilised organic material under different conditions.

Diaporthe glabrae clade: D. etinsideae Y.P. Tan, Grice & R.G. Shivas was introduced by Tan & Shivas (2022) on Annona muricata in Queensland (Australia), based on the diagnosis of sequence data obtained apparently from the type specimen (BRIP 64096a), and no taxonomic description was provided; D. etinsideae is synonymised here under D. tulliensis.

Diaporthe inconspicua clade: D. inconspicua R.R. Gomes, Glienke & Crous was introduced by Gomes et al. (2013) for three endophytic isolates from the medicinal plants Maytenus ilicifolia and Spondias mombin in Brazil, based on the diagnosis of sequence data, since the isolates (including the ex-type strain CBS 133813) were sterile in culture; however, the morphological description of D. inconspicua was later emended by Bezerra et al. (2018) based on a set of endophytic isolates from Poincianella pyramidalis in Brazil phylogenetically related to D. inconspicua, and thus the description provided by Bezerra et al. (2018) was considered here. Similarly, the morphological description of D. isoberliniae Crous on Isoberlinia angolensis in Zambia (Crous et al. 2014b) was emended by Lambert et al. (2023) based on two strains on Pittosporum manii in Cameroon, which produced beta and gamma conidia, features that were not observed by Crous et al. (2014b) for the type specimen; the emended taxonomic description of D. isoberliniae was considered in this synopsis, along with its original description.

Diaporthe leucospermi clade: D. infecunda R.R. Gomes, Glienke & Crous was introduced by Gomes et al. (2013) for a set of eight isolates from leaves of medicinal plants growing in Brazil, such as Schinus terebinthifolius and Maytenus ilicifolia, based on the diagnosis of sequence data, since the isolates (including the ex-type strain CBS 133812) were sterile in culture; D. infecunda is synonymised here under D. leucospermi. D. australpacifica Y.P. Tan & R.G. Shivas was introduced by Tan & Shivas (2022) on a stem of Amaranthus blitum in Norfolk Island (Australia), based on the diagnosis of sequence data obtained apparently from the type specimen (BRIP 60163d), and no taxonomic description was provided; D. australpacifica is synonymised here under D. micheliae.

Diaporthe longicolla clade: D. breyniae Y. Marín & C. Lamb. Was introduced by Matio Kemkuignou et al. (2022) as an endophyte on leaves of Breynia oblongifolia in Cameroon, based on the diagnosis of sequence data, since no sporulation was observed for the ex-type strain CBS 148910 on different media. D. trevorrowii Y.P. Tan, Grice, Czislowski & R.G. Shivas was introduced by Tan & Shivas (2022) on stems of Cucumis melo in Queensland (Australia), based on the diagnosis of sequence data obtained apparently from the type specimen (BRIP 70737a), and no taxonomic description was provided.

Diaporthe rudis clade: D. asheicola L. Lombard & Crous was introduced by Lombard et al. (2014) on Vaccinium ashei in Chile, based on the diagnosis of sequence data, since the two isolates representing the species (including the ex-type strain CBS 136967) could not be induced to sporulate on different media or on sterilised V. myrtillus tissue placed on the media; however, a morphological description for D. asheicola was provided by Chethana et al. (2021b) for a Russian specimen of Diaporthe on a stem of Fraxinus pennsylvanica, phylogenetically related to D. asheicola, and thus the description provided by Chethana et al. (2021b) was considered here. D. cynaroidis Marinc., M.J. Wingf. & Crous was introduced by Marincowitz et al. (2008) on leaf litter of Protea cynaroides in South Africa, but only the sexual morph was reported associated with its type collection, and the asexual morph was regarded as “Phomopsis sp.”; however, a morphological description of the asexual morph of D. cynaroidis was provided by Hyde et al. (2020a) for an Italian saprophyte specimen of Diaporthe on a dead aerial stem of Eupatorium cannabinum, phylogenetically related to D. cynaroidis, and thus the description provided by Hyde et al. (2020a) was considered here. D. subcylindrospora S.K. Huang & K.D. Hyde was introduced by Hyde et al. (2018) as a saprophyte on a dead branch of Salix sp. in China, based on morpho-molecular analyses, but only the sexual morph was observed on the host tissue; D. subcylindrospora is synonymised here under D. cynaroidis. Similarly, D italiana Chethana, Camporesi & K.D. Hyde was introduced by Hyde et al. (2019) as a saprophyte on a dead, aerial branch of Morus alba, based on morpho-molecular analyses, but only the sexual morph was observed on the host tissue; D. italiana is synonymised here under D. rudis.
