The sheathed woodtuft is a popular edible mushroom that grows in tufts on deciduous wood, more rarely on conifer wood. The cap is brownish-yellowish, greasy-glossy and patchy when damp, and the stem bears a lasting, membranous ring. It can be mistaken for the deadly poisonous funeral bell.
It grows in tufts on wood and has a brown spore print. The deadly poisonous funeral bell also grows on wood and looks similar. Confusing the two can be fatal, so it is only for confident experts.
It is usually smaller, its stem is smooth and fibrous below the ring instead of scaly, and it smells mealy. The most reliable feature: the scaly stem below the ring in the sheathed woodtuft. Deadly poisonous. If in doubt, do not eat it.
