Hairy Curtain Crust - Stereum hirsutum


Hirsute means hairy, and indeed the upper surface of these irregularly-shaped tiered brackets is distinctly hairy. Individual brackets are 2 to 8 cm across and have irregularly wavy edges. The colours, which are zoned and generally paler towards the margin, darken with age and vary considerably with location, but yellow, orange and brown are most common and often carrying bands of dark green algae, giving an attractive appearance; the underside is smooth and a consistent ochre yellow colour. There is no stem.

When to see it

All through the year, but shedding spores in autumn.
