Psilocybe Cyanofibrillosa

Psilocybe cyanofibrillosa, known as the Blue Fibrillose Psilocybe, is a moderately potent psilocybin mushroom native to the Pacific Northwest of North America. It is recognized for its distinctive bluish fibrils (fibrous threads) on the cap and stem, especially when bruised. Though less well-known than its relatives like P. cyanescens, it shares similar psychoactive properties and grows in similar habitats.

History

This species was first described in the late 20th century and has been found primarily in coastal regions of Washington, Oregon, and British Columbia. It often grows in wood chips, forest debris, and along streambanks—especially in areas rich in lignin or decaying wood.

Although not widely cultivated, it has become of interest to mycologists and psychonauts due to its subtle but distinctly uplifting and visual effects. Its name reflects the characteristic blue fibrils on the cap and stem—an identifying feature among psilocybin-containing species.

Overview

The mushroom has a convex to flat cap, measuring 1.5–4 cm across, with a reddish-brown to caramel color that darkens when wet. It is covered in fine bluish fibrils, especially near the margin and on the stem, which bruises blue when touched. The gills are adnate and turn dark purple-brown as spores mature.

The effects are described as gentle, clear-headed, and euphoric, with moderate visual and emotional depth. It is usually consumed fresh or dried and is appreciated for its calming and nature-connected experiences. Potency is considered moderate, making it suitable for those seeking a less intense psychedelic experience.
