It produces orange to apricot, lobed, gelatinous basidiocarps (fruit bodies) and is parasitic on other fungi (probably Xylaria species) on dead branches of broad-leaved trees.

Tremella armeniaca was first published in 1996 by American mycologist Robert Bandoni and Costa Rican mycologist Julieta Carranza based on collections made in Costa Rica.

[2] Fruit bodies are gelatinous, orange to apricot, up to 12 mm across, and lobed, sometimes arising in small clusters.

Microscopically, the basidia are tremelloid (ellipsoid, with oblique to vertical septa), 4-celled, 10 to 15 by 6 to 10 μm.

[1] Tremella erythrina is similarly coloured, but was described from China and has larger basidia and basidiospores.
