Jülich Polyporus umbellatus is an edible species of mushroom, found growing on roots of old beeches or oak (e.g.[1]).
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 stalk is whitish grey, and originates from a strong, tuber-like nodule that is underground.
[2] Polyporus umbellatus may contain bioactive compounds with immunostimulating, anticancer, anti-inflammatory, and hepatoprotective properties.
