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)., Published as part of Dentinger, BTM, Gaya, E, O'Brien, H, Suz, LM, Lachlan, R, Diaz-Valderrama, JR, Koch, RA & Aime, MC, 2016, Tales from the crypt: genome mining from fungarium specimens improves resolution of the mushroom tree of life, pp. 11-32 in Biological Journal of the Linnean Society 117 on page 27, DOI: 10.1111/bij.12553, http://zenodo.org/record/7848603, {"references":["Matheny PB, Curtis JM, Hofstetter V, Aime MC, Moncalvo JM, Ge ZW, Slot JC, Ammirati JF, Baroni TJ, Bougher NL, Hughes KW, Lodge DJ, Kerrigan RW, Seidl MT, Aanen DK, DeNitis M, Daniele GM, Desjardin DE, Kropp BR, Norvell LL, Parker A, Vellinga EC, Vilgalys R, Hibbett DS. 2006.
