Ecological studies of ectomycorrhiza are often frustrating because of our inability to name many of the fungal species found on root systems. We hope to improve our ecological studies by repeatedly sampling root systems next to fruiting bodies, allowing us to match morphotypes with mushroom species. Our descriptions differ from most other sources because we rely on root ‘squashes’ when we process the thousands of tips typical of an ectomycorrhiza study. For example, we sometimes have less detail about inner mantles if the outer mantle or emanating hyphae obscures these features in a root squash. Nevertheless, we have found each species has enough distinct characteristics to differentiate between them. The ectomycorrhizae species listed in the table below are linked to Adobe PDF files that provides photographs and line drawings which clarify mantle features. Each of the pages can be printed on legal size paper (11 x 14 inches). This project is an ongoing one, which we will update occasionally with new descriptions (and hopefully few corrections to previous descriptions), and eventually we hope to add DNA analysis. If you have any questions, concerns or comments about the content of this page, please contact Marty Kranabetter.
July 2004 Update. Dr. Keith Egger of the University of Northern British Columbia has found good matches in RFLP patterns between the sporocarps and root tips for almost all of the species listed. A correction was made for Leccinum aurantiacum, and further testing of genetic matches is ongoing.
