Tremella tremelloides is a species of fungus in the order Tremellales. It produces yellowish, brain-like to densely lobed, gelatinous basidiocarps (fruit bodies) and is parasitic on Stereum basidiocarps on dead branches of broadleaved trees. It was originally described from the USA.
The species was first published in 1873 by British mycologist Miles Joseph Berkeley who placed it in the genus Sparassis, interpreting the lobes as compacted branches.[1] It was subsequently transferred to Tremella by George Edward Massee in 1889. American mycologist Robert Joseph Bandoni restudied collections in 1961, placing Naematelia quercina in synonymy and noting a similarity between Tremella tremelloides on broadleaf trees and Naematelia encephala on conifers.[2] As a parasite of Stereum fruit bodies, Tremella tremelloides belongs in the genus Naematelia, but the species has not as yet undergone DNA sequencing to confirm this.[citation needed]
Description
Fruit bodies are gelatinous, hemispherical at first becoming lobed, the lobes often flattened and compact, yellowish, with a denser whitish core when sectioned. Microscopically, the hyphae have clamp connections. The basidia are tremelloid (globose to subglobose, with oblique to vertical septa) and unstalked, 4-celled, 14 to 22 by 12 to 18 μm. The basidiospores are subglobose, smooth, 9 to 12 by 9 to 11 μm.[2]
