A very close relative of P. cyanescens is Psilocybe allenii (described in 2012), formerly known as Psilocybe cyanofriscosa, a mushroom found in California and Washington [13] [11] It can be distinguished by macromorphological features and/or sequencing of rDNA ITS molecular marker.
[115] [116] Except for ornamental purposes, growing, selling or possessing Psilocybe spp. and Conocybe spp. is prohibited by Louisiana State Act 159. The cities of Denver , Colorado , [ 117 ] Oakland, California , [ 118 ] Santa Cruz , California, and Ann Arbor , Michigan have decriminalized the drug.
Psilocybe are found in a variety of habitats and substrates. Many of the species found in temperate regions, such as Psilocybe cyanescens, seem to have an affinity for landscaped areas mulched with woodchips and are actually rather rare in natural settings removed from human habitation. [16]

The most potent species are members of genus Psilocybe, such as P. azurescens, P. semilanceata, and P. cyanescens, but psilocybin has also been isolated from approximately a dozen other genera, including Panaeolus (including Copelandia), Inocybe, Pluteus, Gymnopilus, and Pholiotina.
Psilocybe allenii is a species of agaric fungus in the family Hymenogastraceae. Described as new to science in 2012, it is named after John W. Allen, who provided the type collection. It is found in the northwestern North America from British Columbia, Canada to Los Angeles, California, most commonly within 10 miles (16 km) of the Pacific coast.
The cities of Oakland and Santa Cruz, California, decriminalized psilocybin in June 2019 and January 2020, respectively. Washington, D.C., followed soon in November 2020, as did Somerville, Massachusetts, in January 2021, and then the neighboring Cambridge and Northampton in February 2021 and March 2021, respectively.
Psilocybe cyanescens, Psilocybe allenii, and Psilocybe ovoideocystidiata are known to thrive in urban and suburban environments, particularly in mulch beds [1] This mushroom is typically gregarious, growing in groups of several hundred individuals in one particular area, as well as in multiple small clusters of several mushrooms each, within ...
