Agaricineae Fr., emend. Aime, Dentinger & Gaya

Fries, EM. 1825. Systema orbis vegetabilis, p. 65.

Type family: Agaricaceae Chevall., Fl. gen. env. Paris (Paris): 121 (1826).

Basidiomata predominantly agaricoid or gasteroid; agaricoid development various, including several hemiangiocarpic lineages, but not angiocarpic. Hyphae monomitic, clamp connections present or absent. Basidia 2–4 spored; basidiospores typically pigmented some shade of brown with exception of members formerly placed in Lepiotaceae .

Representative families: Agaricaceae , Psathyrellaceae Vilgalys, Moncalvo & Redhead , Strophariaceae Singer & A.H. Sm. , Crepidotaceae Singer , Hydnangiaceae G aum €. & C.W. Dodge, Hymenogastraceae Vittad. , Inocybaceae J ulich €, Tubariaceae Vizzini. Notes: This corresponds to previously recognized ‘Agaricoid’ clade, which has been consistently recovered as monophyletic in recent studies ( Matheny et al., 2006, 2015; Garnica et al., 2007; Binder et al., 2010; Kohler et al., 2015). Many species in this lineage have basidiospores with a thickened, darkly pigmented wall ( Matheny et al., 2006; Garnica et al., 2007). Although species producing dark-pigmented basidiospores do occur in a few other lineages (e.g. Melanomphalia ), the vast majority of these have diversified within Agaricineae. The present study does not include exemplars from Nidulariaceae Dumort , Cortinariaceae R. Heim ex Pouzar , Inocybaceae J ulich €, or Bolbitiaceae Singer but other studies support their placement here ( Matheny et al., 2006, 2015; Binder et al., 2010).
