If you happen to visit them, perhaps you can straighten them out a bit. None the less, it is good to see they recognize the value of fungi and know that people are interested in them. A brief reference section is also included. That Shoots Like a Cannon that appears at the website of the University of Georgia. The idea is the brianchild of Dr. R.W.

Many modifications are possible.
Almost any kind of dung works. Most of the site is based on text and pictures from the book Working with Mycorrhizas in Forestry and Agriculture by Mark Brundrett, Neale Bougher, Bernie Dell, Tim Grove and Nick Malajczuk, published in 1996 by the Australian Centre for International Agricultural. They make note of the fact that the site is not intended to provide detailed information on physiology, or subcellular structure of mycorrhizae, information applicable outside Australia, or details of techniques used to study mycorrhizae. We just learned of a website for The Kansas Chytridiomycosis Monitoring Program operated out of Wichita State University. The Chytrid Corner currently contains a nice photograph of a very interesting looking species.
