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.
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]
