Type species – Pithomyces flavus Berk. & Broome, J. Linn. Soc., Bot. 14: 100 (1873).
Notes – Pithomyces is similar to other astrosphaeriella-like genera in having dark, carbonaceous ascomata with a poorly developed peridium at the base, trabeculate pseudoparaphyses, cylindrical asci, and fusiform ascospores with acute ends (Wanasinghe et al. 2018a). However, it is distinct from other astrosphaeriella-like taxa in its hyphomycetous asexual morph while others are coelomycetous.
