Psilocybe azurescens Stamets et Gartz, Integration 6: 21 (1995)
P. azurescens is a distinct species, closely related to P. cyanescens. It can be
easily distinguished by macrocharacters (acutely umbonate pileus and fibrillose
annular zone on stipe) and microcharacters (longer spores).
D i s t r i b u t i o n . An American species, introduced to Europe; for the first time
reported from a natural habitat in Germany (Gminder 2001). Its occurrence in Europe
has most likely been caused by recent amateur outdoor cultivation; next
finds are expected in the future. I have also studied one collection found on 19th
October 1966 in Royal Botanic Garden Edinburgh (E 186683) that might be attributed
to this species; however, the herbarium specimen was in a bad state and not
all the features necessary for doubtless identification could be observed.
P h e n o l o g y. Probably similar to P. cyanescens.

Psilocybe serbica M. M. Moser et E. Horak, Z. Pilzk. 34(3–4): 138 (1968)
P. serbica is a very poorly known species (for example, only one colour photo
is available) and further investigation on its morphological variability, distribution
and relationship to other similar bluing species is required.
