Inocybe rimosa, commonly known as the Split Fibrecap or Aufgeplatzter Faserling, is a medium-sized, mycorrhizal basidiomycete mushroom belonging to the Inocybaceae family. It is characterized by a convex to flattened cap, measuring 2-6 cm in diameter, with a surface that often develops radial cracks or splits with age, giving it a distinctive appearance. The cap color ranges from pale brown to yellowish-brown or ochre, often with a slightly darker center. The stem is slender, measuring 4-10 cm long and 0.4-0.9 cm thick, with a whitish to pale brown color and a fibrous texture. The gills are adnate to adnexed, initially pale and becoming brownish as the spores mature. Inocybe rimosa is known for its cracked cap surface, which distinguishes it from other Inocybe species. This fungus is primarily distributed across Europe and North America, where it can be found in deciduous and mixed forests, forming mycorrhizal associations with various tree species, including oak, beech, and birch. It prefers moist, nutrient-rich soil and can be encountered from late spring to late autumn. The spores of Inocybe rimosa are smooth, elliptical, and measure approximately 7-10 x 4-6 µm. Like other Inocybe species, it produces a large number of spores, with a single mature fruiting body capable of releasing millions of them. These spores are dispersed by the wind, allowing the fungus to colonize new areas. Inocybe rimosa is considered inedible and potentially toxic, as it contains the toxic alkaloid muscarine, which can cause symptoms such as sweating, salivation, vomiting, and diarrhea if ingested. Mushroom foragers should exercise caution when collecting mushrooms to avoid accidental poisoning.
