Phaeotremella roseotincta
Phaeotremella roseotincta is a species of fungus in the family Phaeotremellaceae. It produces pinkish to pale pinkish brown, frondose, gelatinous basidiocarps and grows on dead attached and recently fallen branches of broad-leaved trees. It was originally described from Japan and has also been recorded from far eastern Russia.
Description
Fruit bodies are gelatinous, pinkish to pale pinkish brown, up to 4 cm across, and seaweed-like. Microscopically, the hyphae are clamped and occur in a dense gelatinous matrix. The basidia are tremelloid, 16 to 20 by 11 to 18 μm. The basidiospores are globose to ellipsoid, smooth, 7 to 10 by 7 to 9 μm.
Phaeotremella frondosa is a widespread species parasitizing Stereum hirsutum and other Stereum species on broad-leaved trees. It produces brown to pale brown fruit bodies without pink tints. Phaeotremella fuscosuccinea occurs in eastern Asia, but is darker and grows on conifers.
Habitat and distribution
Like all Phaeotremella species, P. roseotincta is a parasite of other fungi. Its host species is, however, currently unknown. It occurs on broad-leaved trees in north-eastern Asia.
