The umbrella polypore (Polyporus umbellatus) is a distinctive and edible mushroom that produces clusters of small, overlapping caps growing from a central stem, creating an umbrella-like appearance that makes it relatively easy to identify in the field.

Identification

This species forms large, branched clusters of circular caps (each 1-4 cm across) arising from a common base. The caps are gray to brown with a small central depression. The underside features tiny pores rather than gills. The entire cluster can reach 20-40 cm across and weigh several pounds.

Where to Find It

Umbrella polypore grows at the base of deciduous trees, particularly oak, in temperate forests across North America, Europe, and Asia. It fruits from late spring through autumn and is associated with decaying roots or buried wood.

Culinary and Medicinal Uses

Young specimens are tender and edible with a mild, pleasant flavor. They’re best sautéed, added to soups, or used in stir-fries. In traditional Chinese medicine, the sclerotia (underground storage structure) of this fungus, called Zhu Ling, has been used for centuries as a diuretic and immune support remedy.
