Type species – Pseudomicrothecium subterraneum (L. Fan, C.L. Hou, P.F. Cannon & Y. Li) Y. Marín, Stchigel, Guarro & Cano

Notes – Pseudomicrothecium was introduced by Marín-Felix et al. (2018) as a monotypic genus to accommodate a single species, P. subterranean (= Melanospora subterranean) found on litter in Japan. The genus is characterised by globose, pale brown to dark brown ascomata, lacking ostioles when mature and shrouded with setae, 2-spored, clavate, evanescent asci with a short pedicel and lacking apical structures and ellipsoidal to citriform, 1-celled, dark brown to blackish ascospores, umbonate and truncate at both ends, with a terminal indistinct germ pore at each end (Marín-Felix et al. 2018). The asexual morph of the genus is undetermined.
