Tremella rubromaculata is a species of fungus in the family Tremellaceae. It produces reddish orange, lobed, gelatinous basidiocarps (fruit bodies) and is parasitic on other fungi on dead branches of broad-leaved trees. It was originally described from Guatemala.
Taxonomy
[edit]Tremella rubromaculata was first published in 1964 by American mycologist Bernard Lowy based on a collection made in Guatemala.
Description
[edit]Fruit bodies are gelatinous, bright reddish orange, up to 2.5 cm (1 in) across, and lobed. Microscopically, the basidia are tremelloid (ellipsoid, with oblique to vertical septa), 4-celled, 17 to 21 by 8 to 11 μm. The basidiospores are ellipsoid, smooth, 8 to 10.5 by 6 to 8 μm.[1]
Similar species
[edit]Tremella dysenterica, described from Brazil, is bi-coloured (yellow and reddish orange) and similarly lobed to subfrondose, but has smaller basidia and smaller spores (5.5 to 8.5 by 4 to 5.5 μm).[2] Elsewhere, Tremella erythrina is similarly coloured, but only known from China.[3]
Habitat and distribution
[edit]Tremella rubromaculata is a parasite on lignicolous fungi, but its host species is unknown. It is found on dead, attached or fallen branches of broad-leaved trees.
The species was described from Guatemala and has also been reported from Brazil[1] and Mexico.[4]
