Conocybula cyanopus
species of fungus
Conocybula cyanopus is a species of fungus that contains psychoactive compounds including psilocybin and the uncommon aeruginascin. Originally described as Galerula cyanopus by American mycologist George Francis Atkinson in 1918. It was transferred to Conocybe by Robert Kühner in 1935 before being transferred to Pholiotina by Rolf Singer in 1950 and finally to Conocybula by T. Bau & H. B. Song in 2024. Conocybula cyanopus is recognized as the type species of Conocybula sect. Cyanopodae.
While the taxon Conocybula smithii has sometimes been considered as a junior synonym of Conocybula cyanopus, this much more common species differs by its distribution, DNA barcode, length of its cheilocystidia and pileocystidia.
Description
Conocybula cyanopus is a small saprotrophic mushroom with a conic to broadly convex cap which is smooth and colored ocher to cinnamon brown. It is usually less than 25 mm across and the margin is striate, often with fibrous remnants of the partial veil. The gills are adnate and close, colored cinnamon brown with whitish edges near the margin, darkening in age. The spores are cinnamon brown, smooth and ellipsoid with a germ pore, measuring 8 × 5 micrometers.

Why this record matters
“Conocybula cyanopus” is worth following because a concise public description often conceals a longer documentary argument. Here, Conocybula, cyanopus and species provides the most credible route into that argument.
The date and method of observation matter as much as the stated conclusion, especially where classification or consensus has changed. The source revision retrieved here is dated Jun 22, 2026. The linked authority identifier is Q1955777. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1918, 1935, 1950 and 2024.
Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
