Photo Share: Fungus on birch

fungus on birch photos shared by Holly
From Wikimedia: Piptoporus betulinus, commonly known as the birch polypore, birch bracket, or razor strop, is one of the most common polyporous bracket fungi and, as the name suggests, grows almost exclusively on birch trees. The brackets burst out from the bark of the tree, and these fruiting bodies can last for more than a year. The velvety cut surface of the fruiting body was traditionally used as a strop for finishing the finest of edges on razors. It is also said to have medicinal properties, and this fungus was carried by "Ötzi the Iceman" – the 5,000 year old mummy found in Tyrol.

The fruiting bodies are pale, with a smooth greyish-brown top surface, with the underside a creamy white and with hundreds of pores that contain the spores. Wood decayed by the fungus, and cultures of its mycelium, often smell distinctly of green apples.
