Marasmius crinis-equi

Taxonomy

The Marasmius crinis-equi was first described by Elias Magnus Fries, a Swedish mycologist, in 1838. The genus name Marasmius is derived from the Greek word marasmos, which means 'drying out'. This refers to the ability of these fungi to revive after drying. The species name crinis-equi translates to 'horse hair', a reference to the thin, hair-like stipe of the fungus.

The cap of Marasmius crinis-equi is typically 1-3 cm in diameter, initially convex and then flattening with age. It is usually a pale brown color, often with a darker center. The stipe is long, thin, and hair-like, hence the common name. The gills are white and fairly spaced apart.

The spores of Marasmius crinis-equi are white, smooth, and elliptical in shape. They are typically 7-10 micrometers in length.

Distribution and habitat

Marasmius crinis-equi is found in various regions across the globe, particularly in temperate and tropical areas. It is commonly found in grasslands and woodlands, often growing on dead wood or leaf litter.

Edibility

While not toxic, Marasmius crinis-equi is generally considered inedible due to its small size and tough texture. It is not used in cooking or medicine.
