Habitat: Bovine, Equine Dung and Enriched Soils
Strain Origin: Unknown
Cap: 25-75 mm in diameter, hemispheric to convex expanding to broadly convex to nearly plane with age. Dark red maturing to golden brown. Surface viscid with apparent gelatinous layer when very wet, soon smooth from drying. Fine fibrillose veil remnants when young that soon disappear. Flesh white soon bruising bluish green.
Stem: 150-200+ mm in length. Typically equal, sometimes slightly enlarged at base, sometimes contorted. Yellowish to buff with a reflective sheen, bruising bluish, hollow. Partial veil membranous leaving a persistent membranous annulus that is well dusted with purplish brown spores even before tearing away from the cap.
Gills: Attachment adnate to adnexed. Grayish coloration in young fruit bodies becoming nearly black in maturity.
Spores: Dark purplish brown, subellipsoid, 13 by 8 micrometers on 4-spored basidia
Formerly misrepresented as Psilocybe azurescens.
Detail of separable gelatinous pellicle: This feature seems to be unique to the “B+” among cubensis. When young and fully hydrated the cap has a transparent amber colored layer of cells that quickly oxidizes upon removal to a more opaque blue gray color. The texture is like a thin stretchable layer of gelatin. Note the area where the pellicle has been removed is dull.
