Hairy Curtain Crust / Spring / Summer / Autumn / Winter / Inedible
Through this post we’re going to be delving into the Hairy Curtain Crust Fungi that is sometimes confused for the Turkey Tails Mushroom.
If you’re anything like me, the sight of fungi peeking out from tree trunks and fallen logs on a woodland walk is always a moment of curiosity and wonder. There’s something magical about the variety of shapes, colours, and textures these hidden gems bring to the forest floor.
One I come across really often is the charming Stereum hirsutum, or hairy curtain crust. It’s not the showiest fungus in the woods, but once you’ve noticed it, you’ll start spotting its delicate, fan-like forms everywhere. Clinging to decaying wood, it seems to drape itself over the surface, its tiny, velvety hairs catching the light.
