Taxonomy

Recent molecular phylogenetics research shows that Phaeolepiota is closely related to and may need to be merged into the genus Cystoderma.[3][4]

Description

The mushroom is large and golden, and its stem has a skirt-like ring.[5] The cap is up to 20 centimetres (8 in) wide and the stem up to 20 cm long. It has a mild smell.[6] The spores are brown,[5] producing a tannish spore print.[6]

Similar species

It can resemble Cystoderma fallax, C. granosum, Gymnopilus spectabilis, and Agrocybe praecox.[6]

Distribution and habitat

It is found throughout North America and Eurasia – often in groups[5] and next to nettles.[7]

Edibility

The fruit bodies have been considered edible and are collected for food in Russia and China.[8] It is not, however, recommended for consumption as it is known to cause gastrointestinal upset.[9][2][1] Studies have shown that this fungus contains untolerable amounts of both cadmium and cyanide compounds. Cooking reduces the concentration of the cyanide compounds present, which may be the reason why it has been consumed in some countries.[10]
