Further Information

Notes (MWS) A very common parasite on *Betula* throughout the UK. It eventually kills the host and continues to fruit on the standing or fallen trunk. The pith of the fungus is pure white, very tough and finely fibrous. Thin slices were used at one time to cover razor-strops which were used for stropping (straightening the cutting edge of) cut-throat razors after sharpening. Strips of the pith were also used by entomologists for mounting insects under the name of "Polyporus Pith", before the days of Plastazote.
