Cystoderma amianthinum, commonly called the saffron parasol, the saffron powder-cap, or the earthy powder-cap, is a small orange-ochre, or yellowish-brown, gilled mushroom. It grows in damp mossy grassland, in coniferous forest clearings, or on wooded heaths. It is probably the most common of the small Cystoderma species. Possibly edible, it is not recommended due to its unpleasant odour and resemblance to poisonous species.
The cap is usually between 2 and 5 cm (0.8–2 in) in diameter, convex to bell-shaped, and later flat with a slight depression around a low umbo. It is dry and powdery, often with a shaggy or fringed margin , and is saffron yellow or orange-ochre. The stem is cylindrical, and has a flaky-granular sheath beneath a fleeting, powdery ring. The gills are white initially, and become creamy later. They are adnexed (narrowly attached to the stem), and initially quite crowded. The spore print is white. The flesh is thin and yellowish, with an unpleasant mouldy smell.
