Tulasnella violea

Tulasnella violea is the type species of Tulasnella. It forms smooth, waxy, violet-pink to grey crusts on the underside of fallen branches and logs. It is normally a wood saprotroph but can form mycorrhizal associations with orchids. It appears to occur worldwide, but its limits are uncertain: it has been treated both as one highly variable species and as several, and its type specimens had not been sequenced when the main molecular work was done.
