Classification: Niessliaceae, Hypocreales, Hypocreomycetidae, Sordariomycetes, Pezizomycotina, Ascomycota, Fungi

Fungicolous. Sexual morph: Ascomata perithecial, solitary or scattered, superficial, globose to subglobose, black, membranaceous, tuberculate, with cylindrical, unbranched, dark brown, tapering setae, collapsing when dry, ostiolate, periphysate. Peridium composed of brown to hyaline cells of textura epidermoidea to textura prismatica. Paraphyses filiform, septate, branched. Asci 8-spored, unitunicate, cylindrical, pedicellate, apex blunt, apical ring indistinct, evanescent. Ascospores uni-seriate, ellipsoidal to fusiform, straight or slightly curved, hyaline, aseptate, becoming brown median cells and hyaline end cells, usually 3-septate, constricted at the middle septum, smooth-walled, guttulate. Asexual morph: Hyphomycetous. Conidiophores mononematous, macronematous, hyaline, unbranched, brown to dark brown, swollen at base. Conidiogenous cells monophialidic, enteroblastic, thicken. Conidia terminal, oval to ellipsoidal, straight or slightly curved, 0–1-septate, hyaline, smooth-walled, guttulate (adapted from Samuels et al. 1997).

Notes – Two Ascocodinaea species, A. polyporicola and A. stereicola (type), were collected from basidiomata of Polyporus sp., Stereum sp. and Trichaptum sp. in the USA (Samuels et al. 1997). This genus was initially placed in Hypocreomycetidae (Lumbsch & Huhndorf 2007). However, Huhndorf et al. (2004a) analyzed LSU sequence data of A. stereicola and found that this species is sister to Colletotrichum gloeosporioides (= Glomerella cingulata). Subsequently, Ascocodinaea was transferred to Glomerellales genera incertae sedis (Hyde et al. 2020e, Wijayawardene et al. 2020). In this study, Ascocodinaea is basal to Plectosphaerellaceae in Glomerellales as an independent clade.

Type species: Ascocodinaea stereicola Samuels, Cand. & Magni, Mycologia 89(1): 156 (1997).

Other accepted species: Species Fungorum – search Ascocodinaea.
