Omphalinaceae was established by Vizzini et al. (2020c) based on the molecular results of several works (e.g., Moncalvo et al. 2000, 2002; Vizzini et al. 2011, 2012a,b; Vizzini and Ercole 2012; Lodge et al. 2014; Sánchez-García et al. 2016; Sánchez-García and Matheny 2017). It encompasses Omphalina and Infundibulicybe characterized by a usually depressed at centre pileus, dry, usually with ochre, reddish brown, rusty, orangish brown tinges; decurrent lamellae; colourless, smooth, inamyloid, acyanophilous, cyanophobic thin-walled spores; hymenophoral trama of interwoven hyphae; pileipellis arranged as a cutis to a trichoderm; pigments intracellular and wall-encrusting; clamp-connections present; habitat on soil, litter, or associated with bryophytes (Vizzini et al. 2020c).
Type genus: Omphalina Quél. 1886.
Other accepted species: Species Fungorum – search Omphalinaceae.
