Polyporus umbellatus is an edible species of mushroom. It is also called umbrella polypore.
Description
[edit]The fruit body is composed of numerous (sometimes several hundred) caps. They are 1–4 centimetres (1⁄2–1+1⁄2 in) across,[1] 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 decurrent, narrow and whitish.[1] The stalk is whitish grey, 2.5–7 cm (1–3 in),[1] and originates from a strong, underground, tuber-like nodule. The flesh is white and soft,[1] hardening with age. The spore print is white.[1]

Similar species
[edit]The caps of Grifola frondosa are less consistently sized and those of Armillaria tabescens have gills.[1]
Habitat and distribution
[edit]The species grows on roots of old beeches or oak.[2] It can be found in eastern North America from May to September.[1]
Uses
[edit]It is a choice edible mushroom.[3]
Bioactive compounds
[edit]Polyporus umbellatus may contain bioactive compounds with immunostimulating, anticancer, anti-inflammatory, and hepatoprotective properties.[4][5][6][7][8][9][10][11]
The sclerotia stage of the fungal life cycle (a compact mass of hardened fungal mycelium containing food reserves) is the one used in Chinese medicine, and a 79.74 Mb reference genome was sequenced to better understand its formation.[12]
