This is one of the common fungus sights around. In fact it is one of the most commonly recorded fungi in Britain. I’m talking of course of the Hairy Stereum or Hairy Curtain Crust (Stereum hirsutum). You’ll find it layered on the dead/fallen wood and stumps of deciduous trees – and it’s appearance is all year round. Shame it’s too tough and leathery to even think about putting in the pan! Damn!
It’s a bracket fungi and has a semicircular shape which is wavy or curtained in appearance. The ‘zoned’ yellow/brown fruiting bodies typically form in many rows, overlapping each other as they go. I think they look quite pretty when in full bloom – especially when there’s a quite a few of them. Each individual cap can grow up to 6 cm in width and can be up to 3mm thick. Older groups of the Hairy Stereum turn green with algae and look like some kind of Martian slime lettuce! (It does!)
So what’s this ‘hairy’ business all about then? Well, on initial viewing you don’t notice, but on closer inspection you can see many hairy tufts along the upper side. And as a bit of extra trivia, hirsutum in latin means hairy. The brighter yellow/orange lower surface, which is smoother, releases the spores. When older, this underside fades to a dull grey/brown.
So to sum up – If you haven’t seen any of these yet – you’re on the wrong planet. And yes – they’re inedible.
