The species was described in 2011 by the mycologists Dimitar Bojantchev and R. Michael Davis who classified it as Cortinarius xanthodryophilus.[2]
In 2022 the species was transferred from Cortinarius and reclassified as Calonarius xanthodryophilus based on genomic data.[3]
Description
The mushroom cap is 6–10 cm (2.5–4 in) wide, convex then flat or uplifted, and yellow then yellow-brown.[4] The gills are notched, crowded, yellow then brown as the spores mature.[4] The stalk is 5–10 cm tall and 1.5–3 cm wide, club-shaped, and sometimes tinted blue.[4]
It should not be consumed due to its similarity to deadly poisonous species.[4]
