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

heaths. It is probably the most common of the small genus Cystoderma. It is not recommended for consumption due to its resemblance to poisonous
species.

Taxonomy

Cystoderma amianthinum was first noted by the Italian-Austrian naturalist

pellicle (cap skin).[1]

Description

The cap is usually between 2 and 5 cm (1 and 2 in) in diameter, convex to bell-shaped, and later flat with a slight depression around a low umbo (central boss). It is dry and powdery, often with a shaggy or fringed margin (appendiculate), 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.[2] The spore print is white.[3] The flesh is thin and yellowish, with an odor that is unpleasant or resembles husked corn.[4]

A very similar form with a markedly radially wrinkled cap, has been separated by some authors, and given the binomial Cystoderma rugoso-reticulatum.[2] Some forms have a whitish yellow cap.[4]

Cystodermella granulosa, and Cystodermella cinnabarina are both redder as a rule, and have adnate gills (broadly attached to the stem).[3]

Distribution and habitat

Cystoderma amianthinum is widespread in Europe and North America, and common in northern

temperate zones. It occurs in mossy woodland, on heaths, amongst grass or bracken, and sometimes with willow.[5] It is often found on acidic soils.[6]

Edibility

Eating is not advised as the deadly toxic Lepiota castanea is a lookalike.[7][8]
