Polyporus umbellatus is a rare[citation needed], edible species of mushroom, found growing on roots of old beeches or oak (e.g.[1]). It is also called lumpy bracket and umbrella polypore.

Description[]

The fruit body is composed of numerous (sometimes several hundred) caps. They are 1–4 cm in diameter, deeply umbilicate, light brown, and form the extremities of a strong, many branched stalk. The compound fungus can be up to 40 cm in diameter. The pores are narrow and white. The stalk is whitish grey, and originates from a strong, tuber-like nodule that is underground. The flesh is white, rather soft when young, although hardens with age.

This fungus has many branched stalks

Edibility and cooking[]

Choice edible.[citation needed]

Bioactive compounds[]

Polyporus umbellatus may contain bioactive compounds with immunostimulating, anticancer, anti-inflammatory, and hepatoprotective properties.[2][3][4][5][6][7][8][9]
