Etymology From the Latin words (blue) and (foot). Description Psilocybe caerulipes has a farinaceous taste and a no to slightly farinaceous odor. The cap is 1 — 3.5 cm in diameter, obtusely conic to convex, and the margin is initially turned inwards, later becoming broadly convex to flattened or somewhat umbilicate while retaining a slight umbo, and at times quite irregular. The surface is viscid when moist from a gelatinous pellicle, but soon becomes dry and shiny, translucent-striate, and decorated with fine fibrillose veil remnants near the margin, often with greenish stains near the margin or a greenish tinge overall. It is cinnamon brown to dingy brown when fresh, hygrophanous, and soon fading to dingy ochraceous buff to cinnamon buff. The flesh is thin,
