Cap: 1-4 cm diameter, conical or bell-shaped then expanded and umbonate, dark brown/purple when moist, especially at the centre, drying pale fawn to ochraceous, covered in white fibrils or tiny scales which are particularly dense at the margin in young specimens
Stem: 3-8 cm long x 0.3-0.7 cm diameter, equal or slightly thicker at base, often curved, brownish, covered at first with the white cottony veil which forms a distinct but temporary annulus and cottony scales below; hollow in age.
Gills: adnate, broad, crowded, dark brown often with violet tinge.
Flesh: brownish-lilac, thin.
Odor: like geranium (Pelargonium).
Spore print: reddish-brown.
Spores: ellipsoid, warted, 7-9 x 4-6 µm.
Habitat and distribution: on the ground in damp woods, often under deciduous trees, and in boggy heaths. Found in Europe and America.
Season: autumn. Uncommon.
Edibility: unknown, but best to avoid, due to prevalence of toxins in other Cortinarius species.
Medicinal properties
Anti-tumor effects
An extract of C. flexipes fruit bodies was able to inhibit the growth of Sarcoma 180 and Ehrlich solid cancers in mice by 80% and 70%, respectively (Ohtsuka et al., 1973).
