Birch polypore
Fomitopsis betulina
A species of Fomitopsis. Also known as Razor strop.
The birch polypore boasts a diverse range of uses. Its robust outer layer has served as a sharpening strop for barbers' razors and as a substrate for mounting insect specimens. Once dehydrated, this fungus was also employed for transporting embers over considerable distances due to its slow-burning properties. The historical utility of the birch polypore extends further; fragments of this mushroom were discovered among the belongings of the five-millennia-old mummy, Ötzi the Iceman.
