Kuehneromyces mutabilis

Sheathed woodtuft

A clustered, brown, hygrophanous mushroom of broadleaf stumps across the Northern Hemisphere, fruiting from spring to late autumn. It is edible and cultivated on hardwood logs, but it closely resembles the deadly Galerina marginata, so wild picking is risky.
