Fomitopsis betulina : Birch Polypore

One of the two mushrooms carried by "Otzi the iceman" over 5,000 years ago! This mushroom is a very common brown rot fungus meaning that in this type of decay, the wood shrinks, shows a brown discoloration, and cracks into roughly cubical pieces, a phenomenon termed cubical fracture. The fungi of certain types remove cellulose compounds from wood and hence the wood turns brown.

Infusion from F. betulina fruiting bodies was popular, especially in Russia, Baltic countries, Hungary, Romania for its nutritional and calming properties. Fungal tea was used against various cancer types, as an immunoenhancing, anti-parasitic agent, and a remedy for gastrointestinal disorders (Grienke et al. 2014; Lucas 1960; Peintner and Pöder 2000; Semerdžieva and Veselský 1986; Shamtsyan et al. 2004).
