Polyporus umbellatus

Polyporus umbellatus

Common Name: Umbrella Polypore

Synonyms: Grifola umbellata, Dendropolyporus umbellatus

Substrate: Ground

Location: Hardwood Forests

Spore Color: White


This is a fairly rare species in many parts. Staff at The Field Museum in Chicago only have two records from that region. Id say it is a bit more common south of Chicago, though, once you get into the Southern Indiana hardwoods. 

This mushroom grows from a hard mass of mycelium underground called a "sclerotiumm" It forms many different branches with a gray petal on each branch. If you find it in an area, look for it again around the same time next year.

Said to be a good edible when young.


Grifola frondosa is similar, but not nearly as branched.
