Bondarzewia berkeleyi, commonly known as Berkeley's polypore, or stump blossoms, is a species of polypore fungus in the family Russulaceae. 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 in 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 outer edges that are cut easily with a knife are quite tender.

Many mushrooms are poisonous and some are lethally poisonous. It can be very hard to distinguish between an edible and a poisonous mushroom.

Although efforts have been made to ensure accuracy on this website, the information may contain errors and omissions and should not be relied upon and be used as any basis for eating any plants or mushrooms.
