This splendid example of the Birch Polypore piptoporus betulinus was spotted growing below Plas y Brenin at the side of our popular canoe pond.
It grows on dead or dying birch trees, it is a sign that Autumn is still with us and winter has not arrived yet. The Birch Polypore attacks the heartwood and the sap wood of the tree and will eventually contribute to the top of the tree falling off. It's firm flesh is well suited to stopping razor blades and it bears the alternative name of Razor-stop fungus.
