Ciri dan struktur
Fruitbodies of P. allenii are variable in size, depending on the substrate in which they grow. The caps are 1.5 - 9 cm in diameter, 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, but dry to yellowish-buff. 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. 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. All parts of the fruitbody stain blue if bruised or handled. 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. The odor and taste of the mushroom is farinaceous—similar to freshly ground flour. Spore prints are dark brown, sometimes with violet shades.
Habitat dan peran ekologis
Psilocybe allenii is found in the northwestern North America, with a range extending from British Columbia south to Los Angeles, California. It is most common in areas up to 10 miles km from the Pacific coast, although it has been collected 100 miles km inland. Fruitbodies grow scattered, in groups, or (more rarely) in clusters, on woody debris, such as wood chips often used in landscaping. Favored substrates include hardwood mulches made of oak, eucalyptus, Douglas fir, and alder. Fruiting occurs in cold weather, generally from late September to January. The species can be readily cultivated on agar, grain spawn, and cellulosic material, including wood chips and sawdust.
