Tremellaceae

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

The family currently comprises the single genus Tremella, containing around 40 species. The name previously covered a much wider range of genera within the Tremellales, but molecular research, based on cladistic analysis of DNA sequences, now places these genera in separate families.
