Tremella roseolutescens is a species of fungus in the family Tremellaceae. It produces rose-pink to salmon, pustular, gelatinous basidiocarps (fruit bodies) and is parasitic on other fungi on dead attached branches of broad-leaved trees. It was originally described from Costa Rica.

Taxonomy[edit]

Tremella roseolutescens was first published in 1996 by American mycologist Robert Bandoni and Costa Rican mycologist Julieta Carranza based on collections made in Costa Rica.[1] The species is considered to be close to Tremella mesenterica, the type species of the genus, and hence belongs in Tremella sensu stricto.[1][2]

Description[edit]

Fruit bodies are gelatinous, rose-pink to salmon, up to 10 mm across, and pustular to cerebriform (brain-like). Microscopically, the basidia are tremelloid (globose to ellipsoid, with oblique to vertical septa), 4-celled, 20 to 27 by 18 to 27 μm. The basidiospores are globose to subglobose, smooth, 11 to 15 by 9 to 11.5 μm.[1]

Similar species[edit]

Tremella salmonea is similarly coloured, but was described from China and has larger basidia and basidiospores.[2] Tremella rosea is also pink, but was described from Austria and has smaller basidia and basidiospores.[3]

Habitat and distribution[edit]

Tremella roseolutescens is a parasite on lignicolous fungi, but its host is unknown. It was originally described from dead, attached branches of an Inga species.[1]

The species is currently known from Costa Rica and Belize.[4]
