We have found this species in well-fertilized cow pastures and dung on Mauna
Kea, Hawai`i and Haleakala, Maui.  Merlin and Allen (J. Ethnopharmacology 40: 21-40.
1993) reported P. subbalteatus  as a psychoactive species that has been collected in
Hawai`i for non-traditional recreational purposes.  If you are considering ingesting
Hawai`i's common dung-inhabiting mushrooms for recreational purposes remember
two things:  1) All mushrooms containing the psychoactive compounds psilocybin and
psilocin are illegal, and collecting them may be accompanied by severe legal
ramifications; and 2) many of the common dung-inhabiting mushrooms of the
Hawaiian Islands (and elsewhere) cause gastrointestinal upset when ingested and
numerous poisoning cases are reported each year from eating these mushrooms.
