Initially proposed as the new species Psilocybe angkoria sp. nov. (Sihanonth and Allen) in 2003. it was later “identified” as P. antioquiensis by Dr. Gaston Guzman. P. antioquiensis was formerly reported from Mexico and South America and the identification of the Cambodian material is now suspect. The holotype from Columbia has yet to be genetically sequenced, but based on published microscopy, it is likely a synonym of P. mexicana (Section Mexicanae). The material offered here was sequenced and is the equivalent of sample “Allen C” in Section Zapotecorum. Without the holotype sequence for a direct comparison for species confirmation, we will label this sample as Psilocybe cf. antioquiensis. It is likely an undescribed species and may go back to its originally proposed name of P. angkoria which we don’t think was ever actually published.

Although laboratory specimens resemble P. mexicana, P. antioquiensis has not been observed to form sclerotia and is not closely related.
