Birch Polypore (Razor Strop) (Piptoporus betulinus)
Survival and practical Uses.
Piptoporus is from the Greek piptein meaning “to fall,” and Latin porus for “pores.” Betulinus
refers of course to Betula spp., the birch upon which it commonly grows.
Wildcrafters may wish to note that forests rich in birch polypore and Fomes fomentarius are poor in Chaga (Inonotus obliquus), and vice versa. That is, it appears that once some fungi have set up home, others are less welcome. The wood decayed by the fungus has the distinct odor of green apples.
