The type locality is the place where the type specimen of a scientific name was collected. It appears in the protologue and in name records. Psilocybe mexicana has its holotype recorded from Oaxaca, Mexico (Species Fungorum); Psilocybe tampanensis was typified from a collection near Tampa, Florida, made on 3 September 1977 (Guzmán and Pollock, 1978).
Canada has its own example. Psilocybe quebecensis was named in 1967 from material collected in Quebec; Index Fungorum now treats it as a synonym of the Mexican Psilocybe aztecorum (Index Fungorum). A type locality stays fixed even when a name is later sunk into another.
A type locality records where one collection was made, not where a species first arose or is common. The 1978 tampanensis paper says the species was then known only from its type locality and that cultures were grown from the type (Guzmán and Pollock, 1978), but it cannot show that later material sold under that name descends from it. Geographic labels on cultivated material are a separate matter again.
