Marasmius rotula [SEP] Introduction
Marasmius rotula is a common species of agaric fungus in the family Marasmiaceae. Widespread in the Northern Hemisphere, it is commonly known variously as the pinwheel mushroom, the pinwheel marasmius, the little wheel, the collared parachute, or the horse hair fungus. The type species of the genus "Marasmius", "M. rotula" was first described scientifically in 1772 by mycologist Giovanni Antonio Scopoli and assigned its current name in 1838 by Elias Fries. The fruit bodies, or mushrooms, of "M. rotula" are characterized by their whitish, thin, and membranous caps up to wide that are sunken in the center, and pleated with scalloped margins.
