Resupinatus

Resupinatus is a genus of fungi in the family Tricholomataceae. Species are saprobic, and often found growing on the underside of decaying wood or sides of decaying woody substrates. The generic name is derived from the Latin resupinus (bent backward, inverted).

Description
Species in this genus have small fruiting bodies, typically less than 1.5 cm in diameter. Basidiocarps are pleurotoid or cyphelloid in shape, meaning they have a reduced stem, and a flattened cap that is kidney-shaped or circular when viewed from above. Gills are well-developed and radiate outwards from an off-center point of origin or lacking.
