Collared Mosscap

The Collared Mosscap, known scientifically as <em>Rickenella swartzii</em>, is a small fungus belonging to the family Repetobasidiaceae within the order Agaricales. <em>Rickenella swartzii</em> is characterised by its diminutive fruiting bodies, which typically feature a small, convex to umbilicate cap and a slender stipe. The species typically grows in mossy substrates, on forest floors, decomposing wood, and soil, where it plays a role in nutrient cycling as a saprotrophic or potentially mycorrhizal organism. It is reported to occur in Belgium, Denmark, Norway, and Sweden, reflecting a distribution across parts of northern Europe. Detailed biological traits including typical lifespan measures and physical dimensions are poorly documented for this fungal species in available literature. The Collared Mosscap is currently assessed as Least Concern on the IUCN Red List, indicating that it is not considered to be at significant risk of global population decline.
