Tremella iduensis is a species of fungus in the family Tremellaceae. It produces yellow, cornute-frondose, gelatinous basidiocarps (fruit bodies) 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. [1]

Taxonomy

Tremella iduensis was first published in 1939 by Japanese mycologist Yosio Kobayasi.

Description

Fruit bodies are gelatinous, bright yellow, up to 2.5 cm (1 in) across, and branched, with cornute (horn-like) fronds. Microscopically, the basidia are tremelloid (ellipsoid, with oblique to vertical septa), 4-celled, 17 to 18 by 12 to 13 μm. The basidiospores are ovoid to ellipsoid, smooth, 8.5 to 9.5 by 7.5 to 8.5 μm. [2]

Similar species

Tremella flava was described from Taiwan as "resembling T. iduensis" but differing in the size of its basidiospores (7 to 9 by 5 to 6.5 μm) and basidia. [3] It has been suggested it may be a later synonym of T. iduensis. [1] Other yellow Tremella species are lobed or foliaceous and lack horn-like fronds.

Habitat and distribution

Tremella iduensis is a parasite on lignicolous fungi, probably species of Hypoxylon. [3] It was originally described from Castanopsis sieboldii and is found on dead, attached or recently fallen branches of broad-leaved trees.

The species is currently known from Japan and China. [4]

<i>Tremella fuciformis</i> Species of edible fungus

Tremella fuciformis is a species of fungus; it produces white, frond-like, gelatinous basidiocarps. It is widespread, especially in the tropics, where it can be found on the dead branches of broadleaf trees. This fungus is commercially cultivated and is one of the most popular fungi in the cuisine and medicine of China. T. fuciformis is commonly known as snow fungus, snow ear, silver ear fungus, white jelly mushroom, and white cloud ears.

<i>Phaeotremella frondosa</i> Species of fungus

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.

<i>Phaeotremella foliacea</i> Species of fungus

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.
