Psilocybe thaicordispora is a species of psilocybin-producing mushroom in the family Hymenogastraceae. It was described as new to science in 2012 by renown Mexican mycologist Gaston Guzmán and his colleagues.

Found growing in the ground at an elevation of 1500 meters, near Huai Nam Dang National Park, Psilocybe thaicordispora is a subtropical rainforest mushroom and yet another enigmatic example of the rich mycota of Thailand.
Its epithet “thaicordispora” places it in the section Cordisporae Guzmán and refers to its Thailandese origins. It is said to have similarities to Psilocybe papuana (Guzmán & E. Horak), known only from Papua New Guinea, and P. dumontii (Singer ex Guzmán) known only from Panama.

The psychotronic fungal species in Thailand, as in most tropical countries, are poorly known, a drastic contrast to the richness of the mycoflora. With considerable destruction of tropical habitats, many species will likely disappear before being documented. Psilocybe thaicordispora is on the mycological map, alongside sibling found simultaneously by Guzman such as Psilocybe thaiaeruginomaculans.
