Pseudoclitocybaceae Vizzini, Consiglio, P.A. Moreau & P. Alvarado, in Alvarado et al., Fungal Diversity. 90:109-133 (2018)

Etymology: from the type genus Pseudoclitocybe

Diagnostic characters: Large- to medium-sized basidiomes (515 cm), tricholomatoid or clitocyboid, pileus umbilicate to convex-applanate, sometimes with persistent umbo, hygrophanous or not, lamellae decurrent, subdecurrent to uncinate; mycelium usually developed superficially on substrate as patches with or without rhizomorphs, rooting in tricholomatoid species; hymenophoral trama subregular to somewhat divergent; context homomorphous with cylindrical hyphae > 4 µm diam., usually with acyanophilic intracellular globules, mixed or not with thromboplerous hyphae, exclusively sarcodimitic in tricholomatoid species; subhymenium ramose, repent, easily dissociated; hymenium usually without cystidia; basidia narrowly clavate, small, mostly < 35 x 8 µm, without siderophilic granulations; loop-like (medallion) clamp connections usually present at least in mycelium; pileipellis a dry or weakly gelatinized cutis, frequently diverticulate, occasionally a trichocutis; spores usually smooth, amyloid or not, acyanophilous, with broad, truncate and prominent apicule; mating behaviour heterothallic bipolar (for documented species); nuclear behaviour holocoenocytic (fordocumented species, spores binucleate and terminal hyphae in the primary mycelium plurinucleate). Probably only saprobic (uncertain for Pogonoloma). Present worldwide, mostly temperate to boreal.

Index Fungorum number: IF823302
