Family Stereaceae Pilát

Summary: The genera in this family are not stable. Aleurodiscus in the old sense is scattered across the phylogeny of the family and thus not monophyletic. Stereum and Xylobolus are more stable but genus boundaries are fuzzy.

This is the core group of stereoid fungi. There are three genera in the Chicago Region. They have a smooth hymenium on a pileate, effused-reflexed, or discoid fruitbody. They cause a white rot on dead wood and are often found in large numbers. Our Aleurodiscus grows on bark of living trees.

Genera in Chicago Region

1. Aleurodiscus sensu lato
2. Stereum
3. Xylobolus

Taxon Information

This is a list of genera that are apparently in the family, based on Index Fungorum and MycoBank. The type species of each genus is listed. When looking at phylogenies it is useful to see what type species are included and where they are positioned.
