Didymopleella
Didymopleella Munk, Dansk bot. Ark. 15(no. 2): 109 (1953).
Index Fungorum number: IF 1557; Facesoffungi number: FoF 12195, 2 morphological species (Species Fungorum 2022), no molecular data available.
Saprobic on soft, decorticated woody material. Sexual morph: Ascomata immersed, globose to subglobose, black, coriaceous, ostiolate, short-papillate, easily detached from the substratum, solitary or gregarious. Peridium comprising 1 layer of relatively large, thin-walled, brown angular cells, arranged in a textura angularis. Hamathecium comprising 2–4 μm wide, dense pseudoparaphyses, unbranched between the asci, branching and anastomosing above the asci. Asci 8-spored, bitunicate, fissitunicate, cylindrical to sub-cylindrical, pedicellate, thick-walled, with an indistinct ocular chamber. Ascospores 1–2-seriate, oblong to ellipsoid, pale brown to olive brown, uniseptate, guttulate, smooth, each end with a sub hyaline with a broadly rounded germ pore. Asexual morph: Unknown.
Type species: Didymopleella cladii (P. Larsen & Munk) Munk
Notes: Didymopleella is characterised by immersed, globose to subglobose, black ascomata, cylindrical to sub-cylindrical, pedicellate, thick-walled asci and oblong to ellipsoid, pale brown to olive brown, 1- septate ascospores. According to Art. 41.5, Didymopleella cladii (P. Larsen & Munk) was invalid. Rulamort (1986) validated the name Didymopleella cladii. There is no study on Didymopleella. Molecular data is lacking. We illustrate the type specimen of D. cladii (C-F-70855) and provide an updated description of the genus. We retain D. cladii in Dothideomycetes genera incertae sedis until sequence data becomes available.
