Birch polypore

Overview

Birch polypore forms substantial annual brackets on dead or dying birch. A short, thick lateral stem joins the fruiting body to its host. White flesh lies beneath a pale grey-brown, papery outer skin, while the underside bears tiny rounded or angular pores rather than gills.

The living fungus breaks down birch wood, helping create deadwood habitat used by other organisms. Kew describes fresh brackets as firm and rubbery or corky; older ones become dark, papery and brittle. Each bracket lasts a season, although new fruiting bodies can return on the same tree in later years.
