Giant Polypore
Meripilus giganteus, the giant polypore, forms very large compound rosettes of overlapping brown caps at the base of trees, mainly beech and oak, and causes a white rot of the roots. Its pore surface bruises brown to black. It does not occur in North America, where reports refer to M. sumstinei.
Edibility disputed; not recommended. Older sources treat it as inedible because of its coarse flesh and mildly acidic taste, while newer sources list young specimens as edible.
Never eat a wild mushroom based on a web page — confirm with an expert.
Mycology is an evolving science: names, classifications and safety information change as research advances. Entries are compiled from cited sources and reviewed, but may be incomplete or out of date — check the sources, and never rely on this library alone to identify or eat a mushroom.
