(1969) Calonarius verrucisporus is a species of mushroom producing fungus in the family Cortinariaceae.

[1] It was described as new to science in 1969 by the mycologists Harry Delbert Thiers and Alexander H. Smith who classified it as Cortinarius verrucisporus.

[2] In 2022 the species was transferred from Cortinarius and reclassified as Calonarius verrucisporus based on genomic data.

Its cap is 3–7 cm wide, convex, brownish-yellow, dry, with firm yellow flesh, and mild odor and taste.

[5] The specimens studied by Thiers and Smith were found growing solitary under Conifers in Silver Lake, California in June.
