Article of the day for May 22, 2019 is Cortinarius violaceus . Cortinarius violaceus, the violet webcap, is a fungus found predominantly in conifer forests in North America and deciduous forests in Europe. The fruit bodies are dark purple mushrooms with caps up to 15 cm (6 in) across, sporting gills underneath. The stalk measures 6 to 12 centimetres (2 1⁄3 to 4 2⁄3 in) by 1 to 2 centimetres (3⁄8 to 3⁄4 in), sometimes with a thicker base. The dark flesh has a smell reminiscent of cedar wood. Though they are edible, the mushrooms' appearance is more distinctive than their taste. The species forms symbiotic (mycorrhizal) relationships with the roots of various plants. It was first described by Carl Linnaeus in 1753, and has undergone several name changes. Other populations once identified as C. violaceus or close to that species have now been described as new and separate species, such as C. palatinus, C. neotropicus, C. altissimus, C. kioloensis and C. hallowellensis.
