Biologist Tom Volk of the University of Wisconsin-La Crosse offers his ghostly fungus of the month in this Web site, just in time for Halloween. Dr. Volk covers just about everything there is to know about Monotropa uniflora (not actually a fungus but a fungus-like member of the blueberry family) and closely related plants. The site includes photos and an audio pronunciation guide. Visitors may also follow links to Dr. Volk's main Web site for a comprehensive guide to fungi in general.
