Canada is suposed to be very good for P.Semilanceata. In the praerie / savana at the end of summer . In europe the season goes from september till the first frost comes . 100 fresh is a good dose . 1 to 5 grams dry weight is usual . I have had a trip off 15 fresh ones . It likes sheep fields , fields that have not been used for years . It does not like pig , chicken or horse shit . Horses and cows fuck good fields up , they trample everything to death and piss every where ( horse piss is caustic ) . It does not like any sort of cultivation , ploughing or chemicals . There is no need to mix them with lemon juice unless you want stomach problems , make a tea , its better for you and it comes on faster . I have never seen any other mushrooms that one could mistake for P.Semilanceata . Look at the gills and the spores after learning how from books or the web . Dont collect anything with ribs on the caps . They are white and stain blue when you squeeze the stems . They do not grow on wood . P.Cubensis is easy to grow outside , just mix the spores with water and spray it on horse / cow shit or compost piles , if its warm enough in your area it should grow .
