Hairy Curtain Crust
Stereum hirsutum
This plant is kept in the atlas for identification and safety, not for use. Read the safety notes below before handling it, and keep it away from children, cats, and food.
Stereum hirsutum has no real place in traditional herbal medicine or the kitchen; it is far too thin, tough, and leathery to eat, and old herbals simply pass over it. Its true value has always been ecological rather than medicinal. Foresters and naturalists have long read its cheerful orange fans as a sign that a fallen branch is doing exactly what it should, quietly rotting down and returning its nutrients to the forest floor. Some natural dyers and mushroom crafters have also gathered its tough, weather-resistant brackets for pressed nature displays and mild dye work, prizing it more for its ruffled shape and color than for any curative reputation.
Safety.
Hairy curtain crust is not poisonous but isn't eaten either, since it's thin, tough, and has no culinary use; handling large dried collections can release spores that bother people with mold or asthma sensitivities.
