| Tremella versicolor | |
Tremella versicolor is a species of fungus in the family Tremellaceae. It produces small, pustular, gelatinous basidiocarps (fruit bodies) and is parasitic on the basidiocarps of Peniophora species, a genus of corticioid fungi, on dead attached or recently fallen branches. It was originally described from England.
Tremella versicolor was first published in 1854 by British mycologists Miles Joseph Berkeley & Christopher Edmund Broome based on several collections from England on basidiocarps of Peniophora nuda on deciduous trees.[1][2]
Description
Fruit bodies are gelatinous, orange-red to brownish red, initially up to 2.5 mm across, and discoid to pustular.[2][3] Eventually they coalesce and become effused cerebriform (brain-like), up to 50 mm across.[4] Microscopically, the hyphae have clamp connections and the basidia are tremelloid (ellipsoid, with oblique to vertical septa), 2 to 4-celled, 14 to 30 by 8 to 11 μm. Sterigmata and basidiospores are not formed in the initial, discoid to pustular stage; instead, clusters of small, ellipsoid conidiospores are released, typically with a thin wisp of ribbon-like hypha still attached.[2][3][5] In the effused, cerebriform stage, smooth, globose to subglobose basidiospores are produced measuring 5.5 to 8 by 7.5 to 10 μm.[4]
