Psilocybe neoxalapensis is a species of psilocybin mushroom in the family Hymenogastraceae. Found in Veracruz, Mexico, it was originally described in 2005 under the name Psilocybe novoxalapensis, [2] but this naming was later determined to be invalid, and it was renamed P. neoxalapensis in 2009. [3] It is in the Psilocybe fagicola complex with Psilocybe fagicola, Psilocybe oaxacana , Psilocybe banderillensis , Psilocybe columbiana , Psilocybe keralensis , Psilocybe herrerae , and Psilocybe teofiloi .

Description

Microscopic characteristics

In deposit, the spores are a deep reddish purple-brown color. The use of an optical microscope can reveal further details: the spores are subellipsoid when seen in side view, and rhomboid in frontal view, with dimensions of (3.5-) 5 - 6 (-7) by 6.5–8.5  μm. The basidia (spore bearing cells of the hymenium), are 14-25 by 4.5-7.5 μm, four-spored. The cheilocystidia (cystidia on the gill edge) have two forms - Type A is narrowly lageniform and measures 15–27 by 5–7 μm, often branched at the apex and type two are subventricose-subcylindrical or narrowly utriform, measuring 25 - 32 x 6 - 9  μm.

<i>Psilocybe semilanceata</i> Species of fungus in the family Hymenogastraceae, native to Europe

Psilocybe semilanceata, commonly known as the liberty cap, is a species of fungus which produces the psychoactive compounds psilocybin, psilocin and baeocystin. It is both one of the most widely distributed psilocybin mushrooms in nature, and one of the most potent. The mushrooms have a distinctive conical to bell-shaped cap, up to 2.5 cm (1 in) in diameter, with a small nipple-like protrusion on the top. They are yellow to brown, covered with radial grooves when moist, and fade to a lighter color as they mature. Their stipes tend to be slender and long, and the same color or slightly lighter than the cap. The gill attachment to the stipe is adnexed, and they are initially cream-colored before tinting purple to black as the spores mature. The spores are dark purplish-brown in mass, ellipsoid in shape, and measure 10.5–15 by 6.5–8.5 micrometres.

The fruit bodies have conical to bell-shaped reddish- to orangish-brown caps that are up to 2.5 cm (1.0 in) in diameter, set atop slender stems 3 to 5 cm long.

<i>Psilocybe allenii</i> Species of fungus in the family Hymenogastraceae

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.

Deconica semiinconspicua is a mushroom native to the state of Washington in the United States. The mushroom is small, rare, difficult to see and, according to Guzmán and Trappe (2005), stains blue where damaged. However, Ramírez-Cruz et al. (2012) state that it is "without a really observable bluing reaction". It was described as a psychoactive species of Psilocybe in section Semilanceatae, but Ramírez-Cruz et al. (2012) found that its macroscopic and microscopic morphological features and its DNA sequence, which Ramírez-Cruz et al. did not publish, were a better match for Deconica. Ramírez-Cruz et al. (2012) also stated that it is very similar to Deconica montana. It can be mistaken for Psilocybe silvatica and can be distinguished by its more conic cap, narrower spores and narrower cheilocystidia.

<i>Psilocybe angulospora</i> Species of agaric fungus in the family Hymenogastraceae

Psilocybe angulospora is a species of agaric fungus in the family Hymenogastraceae. The species was described from Taiwan in 2015 and is also present in New Zealand, where it is considered introduced. As a blueing member of the genus Psilocybe it contains the psychoactive compounds psilocin and psilocybin.
