Psilocybe allenii

Psilocybe allenii

Pileus/Cap: Fruitbodies are variable in size depending on growing conditions. The caps are 1.5–9cm and range from broadly convex to flattened, sometimes with a slight depression in the center. The cap margin is either straight and slightly curved inward, rarely slightly wavy, and sometimes has radial grooves in moist specimens. The surface is smooth, sticky when moist, with a gelatinous cap cuticle that can be peeled. Wet fruitbodies are so slippery that they are difficult to collect. Caps are hygrophanous, and so will change color depending on how moist they are. They are pale orange brown to caramel brown when moist, drying yellowish-buff.


Lamellae/Gills: Have an adnate to sinuate attachment to the stipe, and are initially cream to pale gray brown, but become dark purple as the spores mature.


Stipe/Stem: The cylindrical, hollow stipe typically measures 4–7 cm long by 0.2–0.7 cm thick, with the base slightly thicker. The top of the stipe is pruinose (covered with white powdery granules), while the base is connected to thick white rhizomorphs. The stipe surface is smooth to silky fibrillose (as if made of silky, slender fibers), and its color initially white before yellowing slightly in age. Mycelium at the base of the stipe is white or stained blue. Young specimens have a white partial veil that later disappears, or remains as a zone on the stipe that can be colored purplish brown by spores.


Bruising and spore print: All parts of the fruitbody stain blue if damaged or handled. Spore print purple-brown.


Odor and taste: Farinaceous—similar to freshly ground flour.


Distribution and habitat: Present in both the North and South Islands of New Zealand (DNA confirmed, though seemingly with slight differences in appearance). Recorded in Dunedin, Mid Canterbury, Hamilton and Auckland. Usually found in woodchip in urban areas.
