Furthermore, the toxicity of fresh muscarine is exaggerated
the chances were excellent that Harrison would survive an uncooked
dose. Lathom should have used amanitine, not muscarine - the amanita phalloides,
not the amanita muscaria - and for informed readers, his execution was
a painful miscarriage of justice, a tragic sequel to an incompetent performance
by Defense Counsel.

lose relative of Mexico's
psychoactive species, Psilocybe semilanceata is
a mushroom whose physical appearance
resembles Psilocybe semperviva Heim &
Cailleux and Psilocybe
Stalks generally single, sometimes clustered, from two to four inches in
height, the thickness of a goose quill, thread shaped whitish almost solid, the
tube being very small, glutinous; ring, a little below the cap, scarce
“ Cap, from one to two inches in breadth, of a brown color; in the full. grown
ones hemispherical, always convex, and more or lets glutinous; wet with
rain, it becomes browner and transparent,'so that it sometimes appears
“ Gills numerous, single, of a brownish purple color, clouded; whole ones
about twenty, horizontal, three shorter ones placed betwixt them; they throw
out a powder of a brownish purple color."
With respect to the use of it, he only says, « There is nothing acrimonious or
disagreeable in its taste, yet its appearance will not recommend it to the
lovers of mushrooms."

Figure 10 - Two descriptions of Psilocybe semilanceata from the German-language
literature. The first description (top) was written over a hundred years ago, while the
second one (bottom) dates to 1962. Significantly, the more recent entry classifies the
species as "essentially worthless". Also see Figure 11.
mexicana Heim. Like Psilocybe semilanceata, these
Mexican species thrive in meadows and pastures.
Another common trait among these species is the
rather subdued and subtle quality of their bluing
reaction. Recognition of these similarities with
Mexican species sparked the curiosity of scientists
who wanted to learn more about Europe's
Psilocybe species. A research team that included
A. Hofmann and R. Heim began to study samples
of Psilocybe semilanceata, in collaboration with C.
Furrer, a mycologist who examined fruiting bodies
collected in Switzerland and France. By 1963,
paper chromatography testing had yielded data of
historic significance. For the first time, scientists
