CRUST FUNGI & STEREUMS

Crust fungi are fruiting bodies that are broadly attached to the wood substrate. They lie resupinate or flat on the surface and within the dead wood from which they emerge. All crust fungi are not related to each other. They are found in various orders along with very differently shaped close relatives. 

Stereums, unlike most polypores, do not have visible pores. Their hymenium or fertile surface is smooth. Stereums belong to the Stereaceae family within the Russulales order. In other words, they are closely related to Lactarius and Russulas.

You can see examples of common crust fungi as well as fairly common species of stereum by clicking on their individual scientific names which are listed alphabetically below.
