Phaeotremella is a genus of fungi in the family Phaeotremellaceae. All Phaeotremella species are parasites of other fungi and produce anamorphic yeast states. Basidiocarps, when produced, are gelatinous and are colloquially classed among the "jelly fungi". Fifteen or so species of Phaeotremella are currently recognized worldwide. Tremella sanguinea, shown to be a Phaeotremella species by DNA sequencing, is cultivated in China as an ingredient in traditional Chinese medicine.
Phaeotremella frondosa is a species of fungus in the family Phaeotremellaceae producing brownish, frondose, gelatinous basidiocarps. It is widespread in north temperate regions, and is parasitic on other species of fungi that grow on dead attached and recently fallen branches of broadleaf trees.
Phaeotremella foliacea is a species of fungus in the family Phaeotremellaceae. It produces brownish, frondose, gelatinous basidiocarps and is parasitic on the mycelium of Stereum sanguinolentum, a fungus that grows on dead attached and recently fallen branches of conifers. It is widespread in north temperate regions. In the UK it has the recommended English name leafy brain and has also been called jelly leaf and brown witch's butter. Prior to 2017, the name Tremella foliacea was also applied to similar-looking species on broadleaf trees, now distinguished as Phaeotremella frondosa and Phaeotremella fimbriata.
Naematelia aurantia is a species of fungus producing yellow, frondose, gelatinous basidiocarps. It is widespread in north temperate regions and is parasitic on another species of fungus that grows on dead attached and recently fallen branches of broadleaf trees. It is commonly called golden ear in North America.
Naematelia encephala is a species of fungus producing pink, brain-like, gelatinous basidiocarps. It is widespread in north temperate regions and is parasitic on another species of fungus that grows on dead attached and recently fallen branches of conifers. In the UK, its recommended English name is conifer brain.
Phaeotremella fimbriata is a species of fungus in the family Phaeotremellaceae. It produces blackish, frondose, gelatinous basidiocarps and is parasitic on the mycelium of Stereum rugosum, a fungus that grows on dead attached and recently fallen branches of broad-leaved trees. It is widespread in northern Europe. Prior to 2017, the species was generally considered a synonym of Tremella foliacea, but this latter species is restricted to conifers. Phaeotremella frondosa is a similar-looking but paler, brown species on broad-leaved trees and occurs in North America as well as Europe.
Tremella iduensis is a species of fungus in the family Tremellaceae. It produces yellow, cornute-frondose, gelatinous basidiocarps and is parasitic on other fungi, probably species of Hypoxylon on dead attached and recently fallen branches of broad-leaved trees. It has been recorded from Japan and China. Tremella flava, described from Taiwan, may be a synonym.
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.
Tremella dysenterica is a species of fungus in the family Tremellaceae. It produces bright yellow, red-spotted, lobed to subfrondose, gelatinous basidiocarps 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.
Tremella wrightii is a species of fungus in the family Tremellaceae. It produces light brown to orange-brown, lobed, gelatinous basidiocarps and is parasitic on other fungi on dead branches of broad-leaved trees. It was originally described from Cuba.
Tremella vesiculosa is a species of fungus in the family Tremellaceae. It produces light brown, lobed, gelatinous basidiocarps and is parasitic on other fungi on dead branches of broad-leaved trees. It was originally described from New Zealand.
Tremella samoensis is a species of fungus in the family Tremellaceae. It produces red to orange-yellow, lobed to firmly foliaceous, gelatinous basidiocarps and is parasitic on other fungi on dead branches of broad-leaved trees. It was originally described from Samoa and the Philippines, but is widely distributed in the region.
Tremella brasiliensis is a species of fungus in the family Tremellaceae. It produces yellow, lobed to firmly foliaceous, gelatinous basidiocarps and is parasitic on other fungi on dead branches of broad-leaved trees. It was originally described from Brazil.
Tremella globispora is a species of fungus in the family Tremellaceae. It produces hyaline, pustular, gelatinous basidiocarps and is parasitic on pyrenomycetous fungi on dead herbaceous stems and wood. It was originally described from England.
Tremella roseolutescens is a species of fungus in the family Tremellaceae. It produces rose-pink to salmon, pustular, gelatinous basidiocarps and is parasitic on other fungi on dead attached branches of broad-leaved trees. It was originally described from Costa Rica.
Tremella erythrina is a species of fungus in the family Tremellaceae. It produces orange to red, lobate to foliaceous, gelatinous basidiocarps and is parasitic on other fungi on wood of broad-leaved trees. It was originally described from China.
Tremella armeniaca is a species of fungus in the family Tremellaceae. It produces orange to apricot, lobed, gelatinous basidiocarps and is parasitic on other fungi on dead branches of broad-leaved trees. It was originally described from Costa Rica.
Tremella coffeicolor is a species of fungus in the family Tremellaceae. It produces brown, lobed to foliaceous, gelatinous basidiocarps 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.
Tremella versicolor is a species of fungus in the family Tremellaceae. It produces small, pustular, gelatinous basidiocarps and is parasitic on the basidiocarps of Peniophora species, a genus of corticioid fungi, on dead attached or recently fallen branches. It was originally described from England.
Tremella exigua is a species of fungus in the family Tremellaceae. It produces small, dark, pustular, gelatinous basidiocarps and is parasitic on pyrenomycetous fungi on dead branches of trees and shrubs. It was originally described from France.
