Psilocybe subaeruginascens grows in gregariously and in cespitose clusters in wood chips, piles of leaves, and woody debris in urban areas and along trails and roads in deciduous forests and gardens. It is occasionally found in dung. It is found from April to July in southern Japan and subtropical Java and in Kwazulu-Natal South Africa where it occurs in February and March. A similar species, Psilocybe ovoideocystidiata has been reported from the Bay Area of California.^[1]
