Stereum hirsutum 'group', "Hairy Curtain Crust", is a common, world-wide, wood-rotting fungus found on rotting hardwood logs, branches and sawn timber.
Species best regarded as a closely related 'group'. It can grow flat on the wood surface, then turning out to form dense, overlapping tiers of shelf-like fruiting bodies. Up to 50 mm wide, 35 mm out, 1-2 mm thick, tough, leathery, wavy, lobed and pleated, with great variation in appearance.
Upper surface coarsely or finely hairy, concentrically zoned brown through to yellow, lighter at margin.
(From hirsutum: Latin = hairy.) Lower surface (fertile surface), smooth, with radial bumps or wrinkles, yellow near edge, to brown at attachment. Spore print white, (hard to obtain).
Distinct from Trametes versicolor in that the latter has fine pores. Mushroom Expert ref MykoWeb ref Roger Mushrooms ref Mt Drummer Rainforest Walk, near Cann River, 2010.
