Tremella dysenterica is a species of fungus in the family Tremellaceae. It produces bright yellow, red-spotted, lobed to subfrondose, gelatinous basidiocarps (fruit bodies) and is parasitic on other fungi on dead branches of broad-leaved trees. It was originally described from Brazil and has been recorded elsewhere in the neotropics and in Africa.
Taxonomy
[edit]Tremella dysenterica was first published in 1895 by German mycologist Alfred Möller based on a collection made in Brazil.[1]
Description
[edit]Fruit bodies are gelatinous, bright watery-yellow to deep yellow with orange to scarlet spots and streaks, up to 4 cm (1.5 in) across, and lobed to weakly frondose. Microscopically, the basidia are tremelloid (ellipsoid, with oblique to vertical septa), 4-celled, 14 to 18 by 8 to 12 μm. The basidiospores are ellipsoid, smooth, 5.5 to 8.5 by 4 to 5.5 μm.[2]
Similar species
[edit]Tremella rubromaculata, described from Guatemala without reference to T. dysenterica, appears macroscopically very similar but differs microscopically in having larger basidiospores (8 to 10.5 by 6 to 8 μm) and basidia.[3]
Habitat and distribution
[edit]Tremella dysenterica is a parasite on lignicolous fungi, but its host species is unknown, though collections have been noted on pyrenomycetes.[4] It is found on dead, attached or fallen branches of broad-leaved trees.
The species is currently known from Brazil,[1][2] Belize,[4] and Cameroon.[5]
