Tremella olens is a species of fungus in the family Tremellaceae. It produces soft, whitish, lobed to frondose, gelatinous basidiocarps (fruit bodies) and is parasitic on other fungi on dead branches of broad-leaved trees. It was originally described from Tasmania.
Taxonomy
[edit]Tremella olens was first published in 1860 by British mycologist Miles Joseph Berkeley based on a collection made in Tasmania.[1]
Description
[edit]Fruit bodies are soft, gelatinous, whitish, and lobed. Microscopically, the basidia are tremelloid (ellipsoid, with oblique to vertical septa), 4-celled. The basidiospores are ellipsoid, smooth, 7.5 to 8.5 by 5.5 to 6.5 μm.[2]
Similar species
[edit]Tremella olens belongs to a complex of similar species that have been differentiated by DNA sequencing and minor microscopic features. Tremella fibulifera and T. subfibulifera were both originally described from Brazil; Tremella neofibulifera and T. lloydiae-candidae were originally described from Japan; Tremella australe, T. cheejenii, T. guangxiensis, and T. latispora were originally described from China.[3]
Tremella fuciformis is a white species also recorded from Australia, but fruit bodies have thin, erect fronds, often crisped at the edges.[4]
Habitat and distribution
[edit]Tremella olens is a parasite on lignicolous fungi, but its host species is unknown. It is found on dead, attached or fallen branches of broad-leaved trees.
The species was originally described from Tasmania and has also been reported from Christmas Island.[2] Reports from Venezuela[5] and Jamaica[6] refer to the South American species T. fibulifera or T. subfibulifera. Reports from Cameroon and Sabah belong to the species complex, but which species is uncertain.[2]
