Tremella globispora is a species of fungus in the family Tremellaceae. It produces hyaline, pustular, gelatinous basidiocarps (fruit bodies) and is parasitic on pyrenomycetous fungi ( Diaporthe species) on dead herbaceous stems and wood. It was originally described from England.

Taxonomy

The species was formerly referred to Tremella tubercularia, a nomen novum proposed by Miles Joseph Berkeley when transferring his earlier Tubercularia albida to the genus Tremella (to avoid creating a homonym of Tremella albida Huds.). In 1970, examination of Berkeley's original collections by English mycologist Derek Reid showed, however, that Tremella tubercularia is a gelatinous ascomycete, now known as Ascocoryne albida . Reid therefore described Tremella globispora (as "T. globospora") to accommodate the genuine Tremella species that had previously and mistakenly been referred to T. tubercularia. The type collection from Sussex was on perithecia of Diaporthe eres on dead canes of bramble ( Rubus fruticosus ). [1]

Description

Fruit bodies are gelatinous, hyaline, pustular, up to 0.5 cm across, but sometimes becoming larger (up to 1 cm across) through confluence. They emerge from the perithecia of their host. Microscopically, the basidia are tremelloid (ellipsoid, with oblique septa), 4-celled, 10 to 18 by 9 to 13 μm. The basidiospores are subglobose, smooth, 6 to 8 by 6 to 7 µm. [1]

Similar species

In Europe, Tremella indecorata , described from Norway, is morphologically very similar, though fruit bodies are said to darken when drying. The type collection was associated with pyrenomycetes ( Nitschkia grevillei and a species of Valsaceae) on willow [2] and said to have a spore range of 6.5 to 7.5 µm [2] or 9.5 to 12 by 8.5 to 11 µm. [1] It is not clear if the two species are distinct, though Scandinavian collections identified as T. indecorata are grey to date brown when mature and have larger spores (8.5 to 15 by 8 to 12.5 µm). [3] Tremella karstenii is a similar species parasitic on Colpoma juniperi on juniper. [4] Tremella colpomaticola parasitizes Colpoma quercinum on oak. [5] Tremella subalpina was recently described from rhododendron in Russia. [6]

Outside Europe, Chen considered North American collections as "closely related" to but possibly not conspecific with Tremella globispora. [7] Chen also considered Tremella bambusina , described from the Philippines, as a probable synonym, differing only in its brownish orange colour. [7]

Habitat and distribution

Tremella globispora is a parasite on Diaporthe species and possibly other ascomycetous hosts. It is found on dead, attached or fallen wood and on dead herbaceous stems.

The species was described from England and has been widely reported in Europe. [4] The species has also been reported from Canada [8] and the USA [9] (on Valsa and Diaporthe species) [8] and from the Russian Far East. [6]

<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>Tremella</i> Genus of fungi

Tremella is a genus of fungi in the family Tremellaceae. All Tremella species are parasites of other fungi and most produce anamorphic yeast states. Basidiocarps, when produced, are gelatinous and are colloquially classed among the "jelly fungi". Over 100 species of Tremella are currently recognized worldwide. One species, Tremella fuciformis, is commercially cultivated for food.

<i>Exidia thuretiana</i> Species of fungus

Exidia thuretiana is a jelly fungus in the family Auriculariaceae. The fruit bodies are white and gelatinous with brain-like folds. It is a common, wood-rotting species in Europe, typically growing on dead attached or fallen branches of broadleaf trees, especially beech.

<i>Myxarium nucleatum</i> Species of fungus

Myxarium nucleatum is a species of fungus in the family Hyaloriaceae. In the UK, it has been given the recommended English name of crystal brain. The fruit bodies are watery white, pustular or lobed, and gelatinous with small, white, mineral inclusions visible to the naked eye. It is a common, wood-rotting species in Europe, typically growing on dead attached or fallen branches of broadleaf trees. It is currently not clear whether collections from North America and elsewhere represent the same species.

<i>Phaeotremella</i> Genus of fungi

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.

<i>Naematelia aurantia</i> Species of yellow, parasitic fungus

Naematelia aurantia is a species of fungus producing yellow, frondose, gelatinous basidiocarps.
