Cortinarius bolaris is a mushroom species found in Europe and North America. It belongs to the genus Cortinarius, which is known for its characteristic cobweb-like veil that covers the young fruiting body. The cap of C. bolaris is 3-8 cm in diameter and is convex to flattened with a depressed center. The cap surface is dry and covered with small scales or fibrils. The gills are adnate, crowded together, and yellowish to rusty brown in color. C. bolaris is an ectomycorrhizal fungus, meaning it forms a mutually beneficial association with tree roots. It is commonly found in mixed forests, particularly under oak and beech trees. It typically fruits in late summer to early fall. Chemically, C. bolaris contains the toxins cortinarin and bolaric acid. These compounds are thought to be responsible for the bitter taste of the mushroom and may contribute to its toxicity. The spores of C. bolaris are ellipsoid to almond-shaped, smooth, and measure 8-11 x 5-7 µm. The spore print is rusty brown in color. Recent research has found that C. bolaris may have potential as a source of bioactive compounds with potential pharmaceutical applications. A study published in 2019 identified several compounds from the mushroom with anti-inflammatory activity. Another study from 2020 found that C. bolaris contains polysaccharides that exhibit antioxidant and immune-stimulating properties.
