CHAPTER 3.2
PSILOCYBE CYANESCENS - POTENT MUSHROOMS
GROWING ON WOOD DEBRIS
At least one other Psilocybe species in
addition to Psilocybe semilanceata is known to
exist in Europe. At this point, I must emphasize
that the differentiation of single species within
the Psilocybe genus is subject to considerable
controversy among eminent taxonomists. For
example, there are different methods of
distinguishing the Hypholoma genus from the
Stropharia genus.
The Widespread Distribution
of Psilocybe cyanescens
While Psilocybe semilanceata is a species
that has long been clearly defined and is well
known by this name, there are, according to
Krieglsteiner, other strongly bluing mushrooms
that can be described as belonging to the
"Psilocybe cyanescens complex". These are all
mushrooms that grow on raw compost and plant
debris.
In accordance with current states of
knowledge, the following names in the literature
are merely synonyms for Psilocybe cyanescens
Wakefield emend. Krieglsteiner:
- Hypholoma cyanescens R. Maire
- Hypholoma coprinifacies (Rolland ss.
Herink) Pouzar
- Geophila cyanescens (R. Maire) Kuhner &
Romagnesi
- Psilocybe serbica Moser & Horak
- Psilocybe mairei Singer
- Psilocybe bohemica Sebek
The classification of these synonyms is
particularly difficult, because the mycologists
involved provided detailed descriptions for
isolated collections of fruiting bodies only,
followed by comparisons with mushrooms
found at other locations, using dates provided in
the literature. Under the best of circumstances,
an analysis was performed on dried samples
from
different herbariums. However, the microscopic
data pertaining to the Psilocybe species are poorly
delineated and oftentimes overlap. It is therefore
imperative that additional mycological studies of
Psilocybe cyanescens be performed. To this end,
fresh mushroom samples from various European
locations should be used, and biochemical methods
must be included in the investigation. Guzman's
division of Psilocybe cyanescens by geographic
area, however, definitely turned out to be
inaccurate. According to his system, - North Africa
was home to Psilocybe mairei, while Psilocybe
cyanescens were found in England and Holland and
Psilocybe serbica supposedly grew in Serbia and
Bohemia. The geographic distribution of the entire
species seems to cover a vast area, with variations
along climate and terrain at locations where samples
were collected. Such disparate morphologies are to
be expected when dealing with "young" species,
that is, species that have not yet firmly established
themselves and are still expanding into new
locations.
Figure 7 (p. 14) displays locations in
Europe and North Africa where samples of
Psilocybe cyanescens have been found.
Spores Introduced From Overseas
In this section I would like to discuss
several aspects of the bluing Psilocybe mushrooms.
Detailed information about several isolated sample
collections has been presented by Krieglsteiner.
A description of any mushroom species
becomes valid only after a Latin diagnosis of the
collected sample has been published in a
mycological journal, along with distinctive
characteristics in relation to other species.
In 1946 Wakefield described as Psilocybe
cyanescens Wakefield a sample of bluing darkspored
mushrooms collected at the botanical
gardens in Kew, England. It had been suggested
