SPECIES ATLAS · COMPARE
Compare two species, side by side.
Pick any two of the 58 species in the atlas to see who named each and when, where each name’s specimen came from, every published psilocybin analysis and the records on file. Names and records only: this is not an identification guide.
The comparisons people search for.
- Panaeolus cyanescens vs Psilocybe cubensisBoth turn up under the nickname “Blue Meanies”. iNaturalist lists it as the common name for Panaeolus cyanescens, while a 2025 study’s sample table has a strain called “Blue Meanies” that it assigns to Psilocybe cubensis.
- Psilocybe cubensis vs Psilocybe cyanescensTwo different scientific names that are often compared. “Cyanescens” is also the second word of an unrelated name, Panaeolus cyanescens, and the shared word does not make them synonyms.
- Panaeolus cyanescens vs Psilocybe cyanescensSame second word, different genera. The shared “cyanescens” does not make the two names synonyms, and one of them, Panaeolus cyanescens, is also called “Blue Meanies”.
- Psilocybe azurescens vs Psilocybe cyanescensMost of what circulates online about these two is nicknames and rankings. This compares what the name records and published analyses actually document.
- Psilocybe cubensis vs Psilocybe semilanceata“Liberty cap” is a common name for Psilocybe semilanceata, a name first published in 1818. Most named cultivated labels, Golden Teacher among them, belong to Psilocybe cubensis.
- Psilocybe mexicana vs Psilocybe tampanensisBoth are among the few Psilocybe species that form sclerotia, the compact masses sold as “magic truffles”. Truffles became well known after the Netherlands put psilocybin mushrooms under its Opium Act on 1 December 2008, when the government said sclerotia were not covered.
- Psilocybe cubensis vs Psilocybe natalensisPsilocybe natalensis was published in 1995 from a collection in KwaZulu-Natal. A 2026 paper reported that one commercial “Natal Super Strength” sequence did not match the P. natalensis type, while most named cultivated labels belong to Psilocybe cubensis.
