For the snail genus see Stagnicola Stagnicola is an agaric fungal genus that contains the single species Stagnicola perplexa. This fungus colonizes plant debris in wet coniferous forest floor depressions and shallow pools, and fruits after the pools drain or dry in late summer to early fall in North America (Canada, USA) and Europe. The genus is characterized by smooth, yellowish brown basidiospores lacking a germ pore, and a naucorioid appearance, with brownish mycelium at the base of the stems. Phylogenetically, Stagnicola is rather isolated and may be closest to Mythicomyces and Mythicomyces is closest to the Psathyrellaceae.
