Sample text

Despite 1989 having been a bad year for mushrooms, it was the year when Inocybe aeruginascens was found for the first time at four locations in and around Rostock, a city located on the Eastern German coast, which is famous for its wet climate. Finding the mushrooms at these locations is evidence for a much wider expansion of the species. In coming years, we should expect the species to further migrate into areas with sandy soil. The Inocybe species are mycorrhizal mushrooms, that is, in contrast to other psilocybincontaining species, they require a symbiosis with certain types of wood in order to fruit.

Taxonomic Confusion On May 25, 1986, in the village of Heringsdorf on the Eastern German Sea Coast, I found 147 fruiting bodies of Panaeolus subbalteatus in all stages of development. They were growing on a compost heap that originally contained horse manure. Unlike the Psilocybe species, Panaeolus mushrooms can be found anytime from spring throughout the fall season. The differentiation of Panaeolus species is further hindered because they are very hygrophanous, with caps whose colors can change from whitish to grey, or from reddish brown to a very dark black-brown.

My own analyses of mycelia and 19 fruiting bodies from the Heringsdorf location indicated levels of psilocybin that are fully compatible with the data from the United States: large number of existing synonyms for the species, as presented by Gerhardt (see Figure 31), again indicates substantial taxonomic confusion, as well as insufficient communication and exchange of information. 30(cap) Table 4 shows that the nature and relative amounts of the substances found are different in the fruiting bodies compared to the base mycelium, which was tested here for the first time.
