[4] In 2022 a genomic study was carried out which radically reshaped the family Cortinariaceae resulting in many Cortinarius species being transferred to new or existing genera.

[5] Common names in other languages include Schwachknolliger Klumpfuss (German), Cortinaire à pied glauque (French) and Szálaskalapú pókhálósgomba (Hungarian).

[6] The fruit bodies of this fungus have convex caps 4 to 12 cm (1.6 to 4.7 in) across and ochre or tawny in colour with prominent darker brown fibres.

[10] Phlegmacium glaucopus is found in Western North America (both the United States and Canada),[11] and is common in the Rocky Mountains.

[7] P. glaucopus forms ectomycorrhizae that are unusually hydrophobic (water-repellent) compared with other fungi, which has led to interest in decoding its genome.

DNA studies indicate it may decompose toxic polycyclic aromatic compounds in the soil with specially adapted oxidizing enzymes.
