The 1990 field season constituted the last of a three year study to survey the hypogeous fungi of Grand Teton National Park and the Greater Yellowstone ecosystem. The objectives were to: 1. collect and identify hypogeous fungi found in association with ectomycorrhizal tree hosts such as lodgepole pine (Pinus contorta), subalpine fir (Abies lasiocarpa), Douglas-frr (Pseudotsuga menziesii), quaking aspen (Populus tremuloides), and speckled alder (Alnus tenuifolia), and several species of willow (Salix sp.) throughout the area; and 2. to gain an initial understanding of the importance of these fungi as food for small mammals.
