Thaxterogaster Singer.
Index Fungorum number: IF 19334; Mycobank number: MB 19334
Notes – The centre of the diversity of this genus is in the Southern Hemisphere and it is estimated to include around 200 species. The size of the basidiomes ranges from small to large and varies in coloration from white, ochraceous, greenish, brown to purple. Typical characters for all agaricoid species, however, are a pileipellis duplex and a negative or, more rarely, red KOH reaction. Several lineages of this genus have a honey-like or sweet smell in the context, otherwise known only in Cortinarius subgen. Myxacium. The development of basidiomes ranges from stipitocarpic to pileocarpic type. Six subgenera are currently recognized: Thaxterogaster, Cretaces, Multiformes, Riederorum, Scauri and Variegati (Liimatainen et al. 2022).
