Bulleraceae Bulleribasidiaceae Carcinomycetaceae Cryptococcaceae Cuniculitremaceae Naemateliaceae Phaeotremellaceae Rhynchogastremaceae Sirobasidiaceae Tremellaceae Trimorphomycetaceae The Tremellales are an order of fungi in the class Tremellomycetes.

[2] The order Tremellales was created (as 'Tremellinae') by Swedish mycologist Elias Magnus Fries in 1821 for fungi having gelatinous fruit bodies.

it was amended in 1922 by English mycologist Carleton Rea to include all species, gelatinous or not, in which the basidia were "tremelloid" (globose to ellipsoid with vertical or diagonal septa).

[4] This extended version of the order was not widely adopted, but was used in a number of publications by Martin himself[5] and, as late as the 1970s, by his student Bernard Lowy.

[6] A more precise revision was undertaken in 1984, when Robert Bandoni used transmission electron microscopy to investigate the ultrastructure of the septal pore apparatus in species of the Tremellales.
