Abstract
This installment is one of a series of reports (McKnight, et al 1981, 1982, 1983, 1984) on an extended project studying taxonomy and ecology of ectomycorrhizal macrofungi in and around the Grand Teton and Yellowstone National Parks. It reports the work done on the project during the last year by scientists with specialties as follows: L. R. Batra, Mycology-Plant Pathology; K. T. Harper, Ecology; K. H. McKnight, and M. Moser, Mycology-Taxonomy; K. B. McKnight, Mycology-Biometry. The significance of this program lies in obtaining fundamental information on symbiotic fungi as indispensable intermediates in the uptake of minerals by Tracheophyta. The latter are a major force in building soil regulating stream flow, and in erosion control. This continuing study adds to the inventory of Park fungi (McKnight, 1982) and the supporting documentation of annotations, descriptions, and illustrations. Very little field work was undertaken during the 1984 collecting season, the major emphasis being on analysis of soil and vegetation samples obtained previously.
