Psilocybe subcaerulipes belongs to the section Zapotecorum due to its subellipsoid thin-walled basidiospores. P. subcaerulipes from P. zapotecorum R. Heim emend. Guzmán in the absence of brownish or grayish pseudocystidia, common in that species, that is spread between Mexico and Argentina. It is close to the Mexican species P. muliercula Singer et A.H. Sm.,10 which differs only by the bigger basidiospores, (6‒) 7‒9 (‒10) × (3.5‒) 4‒5 (‒6) × 3.5‒4.5 (‒5) μm, as well as in the poor veil development and distribution. Psilocybe muliercula is only known from Mexico and Colombia, in temperate coniferous (Pinus and Abies) forests, although sometimes it occurs in the ecological boundary with subtropical humid forests. Recently, Ramírez-Cruz, Guzmán and Guzmán-Dávalos discussed P. taiwanensis as a close species of P. thaizapoteca from Thailand and confirmed that they belong to the section Zapotecorum. The only differences among them are the persistent annulus in P. taiwanensis and the strongly branched cheilocystidia in the latter, which we consider variations of the species.
