Tremella steidleri is a species of fungus in the order Tremellales and has the recommended English name brown brain.[1] It produces brown, brain-like, gelatinous basidiocarps (fruit bodies) and is parasitic on Stereum basidiocarps on dead branches of broadleaved trees. It was originally described from the Czech Republic.
The species was first published in 1908 by Italian mycologist Giacomo Bresadola who named it after its collector, the Czech mycologist Emerich Steidler. Bresadola considered it a variety of the smaller, pinkish, conifer species Tremella encephala (now Naematelia encephala).[2] It was subsequently raised to species level by French mycologists Hubert Bourdot and Amédée Galzin in 1928. As a parasite of Stereum fruit bodies, Tremella steidleri belongs in the genus Naematelia, but the species has not as yet undergone DNA sequencing to confirm this.
Description
Fruit bodies are gelatinous, pustular at first becoming compact and brain-like, 30 to 60 mm across, pale to dark, dull, matt brown often with a whitish pruina. Microscopically, the hyphae have clamp connections. The basidia are tremelloid (subglobose to ellipsoid, with oblique to vertical septa) and normally stalked, 2 to 4-celled, 15 to 18 by 10 to 13 μm. The basidiospores are ellipsoid, smooth, 7.5 to 10.5 by 5.5 to 7.5 μm.[3][4]
