OTHER Ps. pelliculosa is actually a separatespecies, but the two are indistinguishable to the naked eye. It growsin sawdust or wood chip piles in forests where lumberjacks have beenworking. The two can be distinguished by spore size, with Ps.pelliculosa spores being smaller at 9-13 x 5-7 x 5-7 micrometers. Ps.pelli. is also weaker in potency, having only 1.2-7.1 mg/g and0.0-0.5 mg/g psilocybin and baeocystin respectively.
Ps. semil. contains more baeocystin than most other Psilocybes,which may account for the subjective difference in quality.
