Auricularia americana is a species of fungus in the family Auriculariaceae found in North America and East Asia.

Molecular research, based on cladistic analysis of DNA sequences, has shown that Auricularia americana is a distinct species.

[citation needed] Auricularia americana forms thin, brown, rubbery-gelatinous fruit bodies that are ear-shaped and 2.5–10 centimetres (1–4 inches) across and about 3 millimetres (1⁄8 in) thick.

[3] Auricularia americana is a wood-rotting species, typically found on dead attached or fallen wood of conifers.

It is widely distributed in North America (primarily in the Northeast, between April and September)[3] and is also known from China and the Russian Far East.
