This site contains no information about the edibility or toxicity of mushrooms.

Kuehneromyces mutabilis, also known as Sheathed Woodtuft, is a medium-sized agaric that has an umbonate honey-brown to yellow hat, which dries from the centre, often producing a two-tone effect. It also has yellowish or reddish-brown gills and a ring on the stem. It grows clustered on stumps and logs of broad-leaf trees, favouring birch. The mushroom can easily be confused with Galerina marginata (Funeral Bell).

Cap convex, becoming broadly convex or nearly flat, and hygrophanous which means it is changing colour as it dries out and fading to yellowish or brownish (often passing through a two-toned stage). Gills adnate and crowded, whitish to pale tan when young, becoming cinnamon brown as the spores mature. Spores are Cinnamon brown. Stem pale and smooth above the ragged stem ring; fibrous, scaly and dark tan below, graduating to almost black at the base.

Many mushrooms are poisonous and some are lethally poisonous. It can be very hard to distinguish between an edible and a poisonous mushroom.

Although efforts have been made to ensure accuracy on this website, the information may contain errors and omissions and should not be relied upon and be used as any basis for eating any plants or mushrooms.
