Notes from Stamets (@1993):

     Introduction: First cultivated in Washington and Oregon
in the late 1970's, this complex of
     is primarily grown outdoors in wood chip beds. Indoor
cultivation is possible but pales in
     comparison to natural culture methods.

     Species in the P. cyanescens complex are not as high
yielding per lb. of substrate as some
     of the fleshier mushrooms in the genus and hence have
little or no commercial appeal.
     However, these mushrooms enjoy a popular reputation and
are sought by thousands of
     eager hunters every fall. Because they are infrequently
encountered in the wild, many
     mycophiles create a mushroom patch in the privacy of
their backyards.

          Common Names: Cyans
          Caramel Caps
          Blue Angels
          Potent Psilocybe
          Fantasi-takes

     Taxonomic Synonyms & Considerations:
     The name Psilocybe is Greek and means "bald head" which
refers to the smooth surface
     texture of the cap. [...]
     This complex of species is fairly easy to identify. The
mushrooms are generally
     cosmopolitan, and virtually absent from virgin forest
ecosystems. They thrive in sawdust
     and chips from alder and Douglas firs. The mushrooms
are collyboid -- forming clusters
     that resemble the genus Collybia in habit only. The
caps are uniquely caramel to chestnut
     colored and strongly hygrophanous. The cap is featured
with a separable gelatinous skin
     and brown gills which produce purple brown spores. The
base of the stems radiate
     clusters of thick white rhizomorphs. Upon bruising, the
flesh turns bluish to dark purple.
     These features separate this group of mushrooms from
all others.

     This group can be further delimited into two sub-
groups: those possessing or lacking
     pleurocystidia. Species having pleurocystida can be
lageniform or fusoid-ventricose with a
     narrow or bulbous apex.

     Description:
          Caps are hemispheric at first, soon convex,
expanding to broadly convex and
          eventually plane in age, 2-l0 cm. in diameter.
Caps are strongly hygrophanous,
          sometimes chestnut especially when old or when the
gills have fully matured. Cap
          margins are typically even at first, and
straightening with age. Some varieties
          develop a pronounced, distinct and undulating
margin.

          Other species in this group have even margins.
Gills are colored brown to dark
          brown, often mottled, and bluntly attached to the
stem, typically with a thin whitish
          margin. The stem is centrically attached to the
cap, silky white to dingy brown near
          the base, often covered with fine fibrils which
may or may not bruise bluish. The
          stems are cartilaginous, even, straight to
sinuous, usually swelling and curved
          towards the base. The base of the stem is usually
fitted with a thick, radiating array
          of white rhizomorphs. Although mushrooms can be
found individually, the majority
          grow in gregarious or collyboid clusters.

     Distribution:
          The species represented in this group of mushrooms
are found throughout the
          temperate forests of the world, including but not
limited to the coastal Pacific
          Northwest of North America, northeastern North
America, the British Isles,
          eastern Europe, southern Argentina, North Africa,
New Zealand and temperate
          regions of Australia.
     Natural Habitat:
          Primarily preferring deciduous woods, especially
in riparian habitats, these
          mushrooms fruit in the fall. Possibly a saprophyte
of fir seed cones, they show a
          particular fondness for the decorative mulch
("beauty bark") used in landscaping
          around newly constructed buildings. In fact, they
are common in urban and
          suburban areas and are actually rare in natural
settings. Ideal locations for
          collecting this mushroom are in the landscaped
property of government facilities:
          courthouses, libraries, utility companies, and
even police stations. Less obvious but
          productive locations are rhododendron, rose and
azalea gardens. These mushrooms
          are frequently found along freeways, around soil
mixing companies, and nurseries.
          These mushrooms are particularly fond of wood chip
piles.
     Microscopic Features:
          Spores are purple brown, 8-12 x 5-7 microns,
ellipsoid, smooth, featuring a distinct
          germ pore at one end. Gill margins are banded with
long throated, finger-like,
          non-forked or forked sterile cells. Some species
have pleurocystidia while most do
          not. Clamp connections are present.

     Mycelial Characteristics:
          These Caramel Capped Psilocybes behave similarly
in creating a luxuriantly satin-
          like mycelia on sterilized malt agar media. The
mycelium is white at first, soon silky
          rhizomorphic, usually radiating outwards with
diverging fans from the location.
          Mycelium often, but does not necessarily, bruises
bluish.

     Fragrance Signature:
          Sour, unpleasant, nearly nauseating to some
people, fragrance reminiscent of
          spoiling corn.

     Natural Method of Cultivation:
          This mushroom conforms to essentially the same
strategy rugoso -annulata. (See
          growth parameters for that species.)
