Agaricomycotina

Agaricomycotina
	Macrolepiota procera (Agaricales)
Scientific classification
Domain:	Eukaryota
Kingdom:	Fungi
Division:	Basidiomycota
Subdivision:	Agaricomycotina; Doweld (2001)
Classes
	Tremellomycetes ; Dacrymycetes; Agaricomycetes; ; Class/Order incertae sedis Bartheletiaceae

The subdivision Agaricomycotina, also known as the hymenomycetes, is one of three taxa of the fungal division Basidiomycota (fungi bearing spores on basidia). The Agaricomycotina contain some 20,000 species, and about 98% of these are in the class Agaricomycetes, which comprises most of the fungi known as mushrooms, including the bracket fungi and puffballs. Species in the Agaricomycotina that are not Agaricomycetes include the jelly fungi, certain "yeasts", ear fungi, and others; these are gathered together as the classes Tremellomycetes and Dacrymycetes. Numerous species of Agaricomycotina are able to produce multicellular fruiting bodies, however, resupinate species form a hyphae structure. Yeast-forming species do not have the capacity to produce fruiting bodies.
