It produces blackish brown, frondose, gelatinous basidiocarps (fruit bodies) and grows on dead attached and recently fallen branches of oak.
It was originally described from far eastern Russia and named after Russian mycologist Eugenia Bulakh.
Fruit bodies are gelatinous, blackish brown with rusty tints, drying black, up to 5 cm (2 in) across, and seaweed-like (with branched, undulating fronds).
The basidia are tremelloid (subglobose to ellipsoid, with oblique to vertical septa), 10 to 19 by 7 to 10 μm.
Phaeotremella fuscosuccinea occurs in eastern Asia, but grows on conifers.
