Pacific Northwest ofNorth America. Two possibilities: either these mushrooms are exceedingly rare
in nature, evolving from micro-niches (such as a minor player in saprophytizing fir cones), and are
now undergoing a population explosion; or these species were just recently introduced fromAustralia
or Europe. The European P. serbica Moser & Horak and Psilocybe
bohemica Sebek, and the Australian
P. australiana Guzman & Watling (= ?P. subaeruginosa Clel.) fall into the Caramel Capped
Psilocybe complex. In any case, the sudden availability of chipped wood for use in landscaping has
brought these autumnal species to the forefront of all the mycoflora found in suburban and urban settings.
They all thrive on paper products, especially cardboard, quickly projecting exquisitely formed,
thick white rhizomorphs. (See Figure 96).
Many gardeners unsuspectingly grow these mushrooms in the course of cultivating ornamental
plants, especially rhododendrOnS and roses. Since mushrooms in this group are some of the few that
thrive well into November in Washington and Oregon, the mycological landscaper is blessed with
