Tremella coffeicolor is a species of fungus in the family Tremellaceae. It produces brown, lobed to foliaceous, gelatinous basidiocarps (fruit bodies) and is parasitic on other fungi on dead branches of broad-leaved trees. It was originally described from Bermuda, where it was collected as part of the Challenger expedition.

Taxonomy[edit]

Tremella coffeicolor was first published, as Hirneola coffeicolor, in 1876 by British mycologist Miles Joseph Berkeley based on a collection made in Bermuda.[1] In 2004, British mycologist Peter Roberts re-examined the type specimen and transferred the species to the genus Tremella. Roberts considered Tremella auricularia, described from Brazil in 1895, to be a later synonym.[2]

Description[edit]

Fruit bodies are gelatinous, pale to mid-brown, several centimetres across, and lobed to foliaceous, the lobes sometimes ear-like. Microscopically, the basidia are tremelloid (ellipsoid, with oblique to vertical septa), 4-celled, 18 to 26 by 12 to 17 μm. The basidiospores are ellipsoid to oblong, smooth, 10 to 12.5 by 8 to 9 μm.[3][2]

Similar species[edit]

Fruit bodies of Phaeotremella frondosa and P. foliacea are similarly coloured, but are typically more frondose and, microscopically, have smaller basidia and basidiospores.

Habitat and distribution[edit]

Tremella coffeicolor is a parasite on lignicolous fungi, but its host is unknown. It was originally described from bark of Coffea.[1]

The species was originally collected in Bermuda[1] and has been recorded from the Azores,[2] Cuba,[2] Trinidad,[2] Jamaica,[4] Puerto Rico, and (as Tremella auricularia) from Brazil.[3][5]
