Collybia eucalyptorum

The fruit body is a mushroom with a cap atop a central stem. The cap, up to 4 centimetres in diameter, is smooth and pale brown but paler toward the margin. It is initially convex but with age may become flat. The gills are cream and the stem (up to 6 centimetres long) is smooth and reddish-brown.

The mushrooms appear in clusters on dead wood or near the bases of live eucalypts.

There is neither a universal nor a partial veil.

Spore print: white.

This is a native species, first described in 1931, based on specimens collected in South Australia.
