The Japanese hallucinogenic mushrooms Psilocybe and a new synonym of P. subcaerulipes with three asiatic species belong to section Zapotecorum (Higher Basidiomycetes).
The subtropical Japanese bluing mushroom Psilocybe subcaerulipes, described by Hongo, has several synonyms P. argentipes by Yokoyama (also from Japan), P. taiwanensis by Guzman and Yang (from Taiwan), and P. thaizapoteca by Guzman, Ramirez-Guillen, and Karunaratna (from Thailand). The study of the holotypes and others specimens of these mushrooms shows that they have basidiospores, pleurocystidia, cheilocystidia, and several other important taxonomic features in common, as well as habitat. Recent discussions of all Japanese hallucinogenic species of Psilocybe and their neurotropic effects are also considered.
