Agaricomycetes Bartheletiomycetes Dacrymycetes Tremellomycetes Agaricomycotina is one of three subdivisions of the Basidiomycota (fungi bearing spores on basidia), and represents all of the fungi which form macroscopic fruiting bodies.

Agaricomycotina contains over 30,000 species,[1] divided into three classes: Tremellomycetes, Dacrymycetes, and Agaricomycetes.

Tremellomycetes contains many basidiomycete yeasts and some conspicuous jelly fungi.

These taxa are founded on molecular research, based on cladistic analysis of DNA sequences, and supersede earlier morphology-based classifications.

[4] The class Bartheletiomycetes contains a single anomalous species of basidiomycete which grows on fallen leaves of Ginkgo biloba.
