Guzmán, Gastón, Laura Guzmán-Dávalos, Florencia Ramírez-Guillén & María del Refugio Sánchez-Jácome. A new bluing species of Psilocybe (Basidiomycota, Agaricales, Strophariaceae) – the first record of section Stuntzii for Mexico. Mycotaxon 103: 27-31. 2008.

ABSTRACT: Psilocybe meridionalis is described as a new species from an oak-pine subtropical forest in the western mountains of the state of Jalisco, Mexico. Because of its bluing feature, annulus and subrhomboid basidiospores, this species belongs to section Stuntzii. The smaller spores and presence of pleurocystidia distinguish this species from the others in the section. This is the first record of a member of section Stuntzii from Mexico.
