Common Names: Berkeley's polypore, stump blossoms
Category: Fungi
Sub-category: Polypores

It is a parasitic species that causes butt rot in oaks and other hardwood trees. The fan- or shelf-shaped caps grow in overlapping clumps from the bases of oak trees, each capable of growing to 25.5 cm diameter. They are various shades of white to pale grey, cream, beige or yellow. The pore surface is white, as is the spore print. The fruit bodies appear over July to October in the United States. It has a similar growth structure to chicken-of-the-woods (Laetiporus sulphureus) however does not have the contrasting orange skin and yellow flesh that the Laetiporus species have.

Edible Notes: Although Bondarzewia berkeleyi is edible, it has been compared to eating shoe leather. The tough white flesh can be up to 3 cm thick and has a mild taste, which can be bitter in older specimens. The outer edges that cut easily with a knife are quite tender.
Warnings: Not known to be dangerous.
