Cap: 40-50 mm long, convexed and plain, hygrophanous and ochraceus with some bluing and blue green along the edge of the cap. Margin translucent-striate.

Gills: adnate to subsinuate, and somewhat violaceous in color at the margin of the gills.

Stem: 50-60 x 4-7 mm. Reddish brown with white scabulous fibrils on stipe. Bruising blue when damaged or with age.

Spores: (5.5-) 6.5-7.5 (-8) (-9) x (4.5) 5-6.

Sporeprint: Violet to Chocolate-brown.

Habitat: Common in the Mexican State of Jalisco, the influence of many new, as well as old ecosystems and microclimates are important for the distribution of these species. Riparian forests extend from sea level to about 2800 m elevation, with species of Populus predominating in arid and semi-arid regions of northern Mexico and species of Alnus in more temperate zones with cooler climates area good habitat for finding this species. Psilocybe villarrealiae is a big mushroom, preferring to grow near rivers and along river creeks with vegetation classified as clod. Subtropical forests appear to be a natural humid habitat for these species, as well as are open spaces and under bushes. Sometimes, large collections of this species can be observed near Magnolia spp, and Alnus spp., where wood debris is buried and mixed with muddy soil, red soil, in pine forest mixed with oaks, and in subtropical forests near small creeks.

Distribution: It has a logistic distribution in Jalisco and can be found in the towns of San Sebastian del Oeste, Mascota, and Zapopan. Psilocybe villarrealiae also occurs in many other regions of Jalisco such as in Sierra de Quila

Season: Generally, rainy season occurs in certain parts of Mexico from June through September. However, we report that sometimes the mushrooms appear as early as May and continue to fruit until October.

Dosage: Unknown.

Comment: Psilocybe villarrealiae acts as a second decomposer, growing from sawdust, which we were able to observe in the town of Mascota, and we also found it to be growing out doors as well.
