Not RANDOM.....What you want to have a good idea of what your looking for....for example around me I have Gymnopilus (more uncommon) and P.Subbalteatus ....Both are closer to a decomposer of grass and wood then they are a poo lover like psilocybe
Gymnopilus
Pan. Subbalteatus
It make's it easier and safer if you first understand what your hunting....Goog your location and type in P cubensis and P cyanescens .....To see what pop's up ......Read the characteristics Like above P sub's leave a black spore print and have a very distinctive ring on the cap ....Some do not bruise like them for example somthing to do with cell structure.....
But Cubensis and cyanescen do....

and heres some examples of bruising pans
NOTE how they turn to a dark Blue where handled...This species is rampant down in FL,GA,AL.....And will almost alway's be found on DUNG (P.Cyan)which is why if I was gonna hunt em that is where I would start.....
