Index Fungorum number: IF 553178; Facesoffungi number: FoF 03262, 1 morphological species (Species Fungorum 2022), 1 species with molecular data.
Saprobic on decaying wood. Sexual morph: Ascomata superficial, solitary or scattered, globose to subglobose, black, setose, coriaceous, with a central ostiole. Ostiole single, central. Setae covering the whole ascoma, dark brown to black, taper to an acute apex, unbranched, thick-walled. Peridium composed of several layers of cells of textura angularis. Hamathecium branched pseudoparaphyses. Asci 8-spored, bitunicate, fissitunicate, cylindrical to clavate or saccate, apically rounded, short pedicellate. Ascospores fasciculate, fusiform, hyaline, slightly curved, tapering toward the ends, guttulate, 5–6-septate, not constricted at the septa. Asexual morph: Hyphomycetous, chlamydosporous. Conidiophores lacking. Chlamydospores holoblastic, sometimes intercalary, broadly oval to ellipsoid, dictyoseptate, pale brown when immature, darkened to black when matured (adapted from Brahmanage et al. 2017).
Type species: Dictyospora thailandica Brahaman., Y.Z. Lu, Boonmee & K.D. Hyde
Notes: Dictyospora resembles Chlamydotubeufia in both asexual and sexual morphs, but both are distinct genera based on phylogenetic analyses. Dictyospora forms a separate lineage in Tubeufiaceae and is a well-supported genus. Molecular markers available for Dictyospora are LSU, SSU, ITS, RPB2 and TEF-1.
