The type of this species was originally found in Australia and is considered to be synonymous with Anthracophyllum archeri (see Pegler 1965).

Gregarious. Pileus horizontal, laterally attached by a thickened stem-like point but sessile, reniform, or almost circular, very thin, flexible when dry, glabrous or minutely cracked under a lens, rust-colour or dark-red, almost even, margin often more or less lobed, the extreme edge drooping and held down by the gills, about 1 cm. across; gills distant, radiating from the persistently pale thickened point of attachment of the fungus to its support, rather distant, broadest in front, not usually connected by veins, becoming blackish; spores dingy, subglobose, 4-5 µ, diameter.

New Zealand. Australia.

On small twigs and branches.

In some of Drummond's specimens the pretty cockle-shell-shaped pilei are crowded on the branches. There are fine specimens from New Zealand in Berkeley's herbarium. Disinguished by the reddish pileus and very thin flexible flesh.
