Panaeolus cyanescens[1] is a mushroom in the Bolbitiaceae family. Panaeolus cyanescens is a common psychoactive mushroom and is similar to Panaeolus tropicalis. It is also known under the common names of Blauender Düngerling, blue meanies, faleaitu (Samoan), falter-düngerling, Hawaiian copelandia, jambur, jamur, pulouaitu (Samoan), taepovi (Samoan), tenkech (Chol).[2]
Description
Cap: 1.5 – 4 cm across, dry, at first hemispheric, expanding to campanulate to convex, with an incurved margin when young. Young caps start out light brown and fade to off-white or light gray at maturity, sometimes with yellowish or brownish tones. Often developing cracks in dry weather, slightly hygrophanous, turning greenish or blue where damaged.
Gills: Broadly adnate to adnexed attachment, close, starting out gray and turning black as the spores mature. Gill faces with a mottled appearance, edges white.
Spores: Jet Black, 12 - 15 x 7 - 11 μm, smooth, opaque, elliptical. With a germ pore.
Stipe: 7 – 12 cm long by 2 to 3 mm thick, equal to slightly enlarged at the base, pruinose, colored like the cap, staining blue where bruised.
Laussmann & Sigrid Meier-Giebing (2010) reported the presence of psilocybin at 2.5% and psilocin at 1.194% average from 25 samples seized by German customs that were shipments from commercial growers (making modern commercially cultivated strains of this species the most potent hallucinogenic mushrooms ever described in reputable published research).[4] Other researchers have documented a significant presence of serotonin and urea in this species as well as the presence of baeocystin which may also be psychoactive.[5][6]
