Extract from Wikipedia article: 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 genus Cystoderma. Possibly edible, it is not recommended due to its unpleasant odour and resemblance to poisonous species.

Cystoderma amianthinum is a small to medium-sized agaric fungus with a bell-shaped to convex cap that is 1-4 cm in diameter, typically colored yellow to golden brown with a powdery or felty appearance. The gills are free from the stem and white to pale yellow. It has a slender stem that is 2-6 cm tall and 0.2-0.5 cm thick, often with a powdery or hairy surface.

It can be found growing solitary or in small groups on the ground in wooded areas, including forests and woodlands.
