Collared Parachute

The Collared Parachute, known scientifically as <em>Marasmius rotula</em>, is a small saprotrophic fungus belonging to the family Marasmiaceae within the order Agaricales. <em>Marasmius rotula</em> is characterised by its distinctive wheel-like or parachute-shaped cap, which typically features radial gill-like ridges connected to a collar around the stipe rather than attaching directly to it — a feature that gives the species both its common and scientific names. This species typically grows on decomposing leaf litter, dead woody material, and forest floors in deciduous and mixed woodland. It is reported to occur in Belgium, Brazil, Denmark, Norway, and Sweden. As a decomposer, <em>Marasmius rotula</em> plays a role in nutrient cycling within forest ecosystems. Detailed biological traits including typical lifespan measures and physical dimensions are poorly documented for this species in available literature. The Collared Parachute is currently assessed as Least Concern on the IUCN Red List.
