As promised here are some pictures of a Mexican strain of Caerulescens (where they are called "Derrumbe"). Its from Tonila region and does look slightly different from the US Strain I am growing atm. and posted before.
this grow is from way back in 2010 and over the years didn't regrow, ending with non viable spores.
They are a potent Psilocybe species and one of the "original" species being used by Curanderas/os in Mexico Oaxaca region. (with the famous village Huautla de Jiménez)
