False Tinder Fungus

Phellinus igniarius

Type: Polypore

False Tinder Fungus

Physical Characteristics

The fungus appears as bracket-like or hoof-shaped growths on the side of the decaying log. The surface of these fruiting bodies is greyish to whitish, somewhat rough or bumpy, and they seem to have concentric growth rings. The underside (pore surface) is not clearly visible but typical for polypores, it would consist of a dense layer of pores.

Habitat & Growing Conditions

Growing on a decaying log, indicating a preference for dead wood as a substrate. Likely found in wooded areas, forests, or anywhere dead hardwood or softwood logs are present.

Season & Fruiting Time

Found year-round, as these perennial polypores can persist for multiple years on their substrate.

Similar Looking Species

Clypeus artemisiae (Artist's Conk) or other Phellinus species. Distinguishing features often involve examining the pore surface, context color, and spore characteristics, which are not visible in this image.

Ecological Role

This fungus is saprophytic, meaning it derives nutrients from decaying organic matter, in this case, dead wood. It plays a crucial role in the decomposition of wood, returning nutrients to the ecosystem and helping to clear fallen timber.

Safety reminder

AI mushroom identification is a best-effort estimate and can be wrong. Never use it to decide whether a mushroom is safe to handle or eat — always confirm with a qualified mycologist before any consumption.
