Strain Origin: Georgia, USA
Initially, this sample was described as Psilocybe atlantis and we assumed that was correct since no similar species were known in Georgia. Samples sent to Psilocybe expert Gaston Guzman cast some doubt on the mushroom's actual identity, but no alternative identification was suggested.
A direct comparison of samples with the published description of P. atlantis has confirmed Guzman's findings. The strain ATL#7 is not Psilocybe atlantis but is instead a related species in the Section Mexicanae. This new collection closely resembles Psilocybe galindoi (galindii), a species previously known only from Mexico. For lack of a better name, we are going to unofficially call this sample Psilocybe galindoi var. Georgia. If this species is described in a scientific journal and given a different name, we will amend this description. Efforts are now underway to provide authenticated spore samples of Psilocybe atlantis.
Both species can be viewed in the Sporeworks Microscopy Gallery Section Mexicanae for side by side comparisons of microscopic features. Note that the authentic Psilocybe atlantis cheilocystidia are irregularly branched and the Psilocybe galindoi var. Georgia cheilocystidia are unbranched. Psilocybe atlantis spores are also somewhat smaller. Currently, no mushrooms matching this collection have been described as occurring in the United States.
