Psychoactive Morels

[Steven Carpenter]

Many years ago I spoke with some people who had eat large amounts of
morels over a period of several days.  They experienced a minor loss of
coordination temporarily, such as not being able to get the fork of morels
to their mouth on the first try.  Whether they were eating morels or
Verpa I cannot vouch.

This wouldn't account for a true psychoactive response, but mimics some
of the side-effects.
