There's a good section on microscopical techniques in the book ' Ammirati
JF, Traquair JA, ANd Horgen PA.  Poisonous Mushrooms of the Northern
United States and Canada.  Minneapolis: University of Minnesoata Press,
1985.  I believe it is now is now out of print, but most good main public
libraries will either own a copy or can get you one on loan.

If you don't already know, the Toxicology group in the North American
Mycological Asociation (NAMA) has a special project going on making
posters aimed at persons from SE Asia because they "recognize" mushrooms
with a volva as all being straw mushrooms. I just saw a copy in my last
mailing from them.
