The [[Pileus (mycology)|cap]] is {{convert|1.6-8|cm|1|abbr=on|frac=4}}, [[conic]] to [[wikt:convex|convex]] with a central papilla when young, becoming broadly convex to plane with age, retaining a slight umbo sometimes surrounded by a ring-shaped depression. The cap surface is [[Glossary of botanical terms#glabrous|smooth]] and sticky, sometimes with white [[universal veil]] remnants attached. The cap is brown becoming paler to almost white at the margin and fades to more golden-brown or yellowish with age. When bruised, all parts of the mushroom stain blue. The narrow grey gills are adnate to adnexed, sometimes seceding attachment, and darken to purplish-black and somewhat mottled with age. The gill edges remain whitish. The hollow white [[Stipe (mycology)|stipe]] is {{convert|4-15|cm|0|abbr=on}} high by {{convert|0.4-1.4|cm|1|abbr=on|frac=4}} thick, becoming yellowish in age.<ref name=singer1958>{{cite journal |doi=10.2307/3756197|jstor=3756197|title=Mycological Investigations on Teonanácatl, the Mexican Hallucinogenic Mushroom.
