Birch bracket
Birch Bracket (Piptoporus betulinus - also known as 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. Technically, it is an edible mushroom, with a strong, pleasant "mushroomy" odour but a bitter taste. It is said to have medicinal properties, and the velvety cut surface of the fruiting body were used as a strop for finishing the finest of edges on razors. Dried specimens have also been used as tinder, and this fungus was carried by "Ötzi the Iceman" - the 5,000 year old mummy found in the Tyrol. It is a necrotrophic parasite on weakened Birches, and will cause brown rot and eventually death, being one of the most common fungi visible on dead Birches.
