all seem to have annoyingly similar characteristics, even the microscopic ones. Psilocybe caribaea and Psilocybe guilartensis both have subrhomboid spores and a dark cap. P. caribaea tends to have a larger cap (35-60mm), as compared to P. guilartensis (15-20)… my collection had a cap of 30mm, so I leaned towards the larger of the two.
However, looking more, P. guilartensis does have a more similar habitat (on clay, pathsides, landslide, disturbed areas), and is more common. One of the defining charcteristics of P. guilartensis is having two distinct types of pleuro- and cheilocystidia… Which I have not looked at.
I’ll pay more attention… I almost didn’t make this collection (hence the bad photos), I’m a little LBM-phobic.
I hope they come back so we can see more pics.
These are definitely P. guilartensis. The yellowish mycelium on the base is one of the defining characteristics of this species.
P. caribaea more resembles P. caerulescens than it does P. guilartensis.
Your photos match up well with my 2008 collection.
