Description

A corky bracket with a hairy pale-zoned upper surface and a gill-like labyrinthine fertile surface, often on birch.

Identification features

Cap 2–10 cm wide, flattened, whitish-grey and hairy, often distinctly zoned. The underside has long gill-like pores that branch and interconnect.

Identification checklist

The underside is key: instead of round pores it has long gill-like, often labyrinthine connected structures.

How to separate similar species

Trametes species have true tubes or pores rather than a distinctly gill-like fertile surface.

Grows in groups on stumps and dead wood of birch and other hardwoods throughout the year.

Fruiting period

January, February, March, April, May, June, July, August, September, October, November, December
