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, 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.
