Psilocybe Serbica could be referred to as the “little brown mushroom” of central Europe. Known from approximately twenty-five localities in the Czech Republic, this psychoactive wood-rotting bluing Psilocybe presents a morphological variability that has had it confused with many other psilocybin species.
It was until recently known as Psilocybe bohemica (1983), P. arcana (2001), P. moravica (2003).
It shares very close taxonomic similarities with Psilocybe cyanescens, though it lacks the particular wavy cap margin of the latter, and in 2015, additional molecular studies published by Borovička and colleagues identified it to be close to P. azurescens, P. cyanescens, P. weraroa, P. cubensis, and P. allenii.
Needless to say, the complex time-consuming recording of the science of mushroom is still in the making.
