Abstract
This study attempts to inventory the mushrooms and related fungi of the Park and to assemble correlative data useful in park resource management and utilization. It is directed toward (1) determining what species of higher fungi grow in and around Grand Teton National Park; (2) appraising their role in the ecosystem; and (3) preparing descriptions, illustrations, and where possible, keys for the common species. Fungi included are mostly Ascomycetes and Basidiomycetes with large or otherwise conspicuous fruiting bodies. Collecting is not confined to Grand Teton National Park but includes sites with similar ecology in the areas surrounding the Park.
