Microporellus Murrill 1905, in Cui, et al., Fungal Diversity 97, 137392 (2019)

Diagnosis: Basidiocarps annual, centrally or laterally stipitate; stipe often somewhat reduced to a long tapering base. Pilei round, single or confluent, tomentus to glabrous, gray to pale buff, concentrically zonate, coriaceous when fresh, rather hard when dry. Pore surface pinkish buff to pale ochraceous; pores small. Context white to ochraceous. Hyphal system dimitic; generative hyphae with clamp connections; skeletal hyphae present in trama, absent or present in the context, dextrinoid or negative in Melzers reagent. Basidiospores ellipsoid to obovoid or subglobose, hyaline, smooth, thin- to slightly thick-walled, IKI, CB–.

Index Fungorum Number: IF18062

Type species: Microporellus dealbatus (Berk. & M.A. Curtis) Murrill 1905

Notes: Microporellus usually has stipitate basidiocarps, a dimitic hyphal system, clamped generative hyphae, slightly dextrinoid skeletal hyphae, and hyaline, thin- to slightly thick-walled, ellipsoid to obovoid or subglobose basidiospores (Gilbertson & Ryvarden 1987). Only one species of this genus is known from China (Dai 2012).
