What is "tremellales"

The Tremellales are an order of fungi in the class Tremellomycetes. The order contains both teleomorphic and anamorphic species, most of the latter being yeasts. All teleomorphic species in the Tremellales are parasites of other fungi, though the yeast states are widespread and not restricted to hosts. Basidiocarps (fruit bodies), when produced, are gelatinous.

The order currently comprises 8 families, containing around 300 valid species. Significant genera include Tremella, two species of which are edible and commercially cultivated, and the yeast genera Cryptococcus and Trichosporon, several species of which are human pathogens.
