green ribbon for organ donor awarenessWelcome to my fungus web page! I hope you will enjoy learning something about lots of different kinds of mushrooms and other fungi.
August 9, 2010 - It 's been over four years since my heart transplant! For those of you who don't know, after having heart problems for several years, on May 22, 2006, I was fortunate enough to receive a new heart at the Mayo Clinic in Rochester!!! I am doing quite well. Thanks for all of your support. I really appreciate it. You can read more at my health update page. Even though I may never know who they are, I am very grateful to the person and the family who donated their heart to me. You can click on the ribbon to the right to find out how to become an organ donor in your state. Please sign up and potentially share your life with others. Thanks!

 The fungus of the month for August 2010 is Laccaria bicolor, a mutualistic fungus and pioneer in genome sequencing. With co-author Todd Osmundson.

 The fungus of the month for May is Geomyces destructans, a fungus associated with bat White-Nose Syndrome (WNS). with co-authors David Blehert, Andrea Gargas, Marie Trest, and Martha Christensen.

I'm sorry I have been way behind on the Fungus of the Month, but I am starting to catch up. I am actively seeking co-authors for Fungus of the Month pages. If you'd like to give it a try, contact me at my email address below. I need your help! You don't have to know html-- I can do all that.

 I recommend doing a search of my pages before writing to ask any questions.

Updated August 9, 2010. Welcome to Tom Volk's Fungi ! My web page went online November 25, 1995, although I had several hundred images online on a "gopher" server starting July 1994. The first month I had 158 hits, mostly from my reloading the page to see if it was still online. By contrast, last month there were more than 17,000 hits on this page. In the past 14 years I have had more than 990,000 hits on this main page (173,000+ in the past year), with untold millions on all my pages and images. These pages have been viewed in 216 countries (apparently being blocked in North Korea). Thanks to all the non-professional and professional mycologists, students, teachers and the myco-curious who have visited and revisited my pages.

A couple years ago, I was featured in "La Crosse Magazine," published by Severson Design. You can view the pdf of the file here. It has one of the few pictures of me that I don't hate. Thanks to La Crosse Magazine for the nice feature!

I am very grateful to Mike Clayton of the UW-Madison Botany Department for getting me started and for hosting my pages all these years. Visit his Botany Instructional Technology web page at  You'll be very impressed.

Please read some of the 350 or so webpages made by my students in Organismal Biology, a class I have now taught three times. Each student could choose any organism and make a web page about it. Of course many of them chose the "charismatic megafauna," but some chose more interesting organisms. In future years students will not be allowed to repeat previous organisms, so we got the pandas and the cheetahs and the elephants out of the way. Some of the pages are very creative, and I have been very impressed with the overall quality. Please visit
