It produces white, foliaceous, gelatinous basidiocarps (fruit bodies) and is parasitic on other fungi on dead wood of broad-leaved trees.

[1] Molecular research, based on cladistic analysis of DNA sequences, showed that the yeast was closely related to the type species of Tremella and in 2015 the species was accordingly recombined as Tremella yokohamensis.

[2] Subsequently, a fruit body collected in the Russian Far East was found to have identical DNA, enabling a more complete description of the fungus.

Microscopically, the basidia are tremelloid (ellipsoid, with oblique to vertical septa), 4-celled, stalked, 18 to 21 by 9.5 to 10.5 μm.

[3] The species was originally isolated as a yeast in Japan[1] and as a basidiocarp in the Russian Far East (Primorye Territory).
