Heald in 1915 and enlarged and improved by Professor Charles Gardner Shaw, the Charles Gardner Shaw Mycological Herbarium contains approximately 75,000 specimens of fungi, which are available through online databases. The Herbarium includes all major groups of fungi, with particular strength in smuts, downy mildew fungi, pyrenomycetes and forest tree pathogens. Although the parasitic fungi of the Pacific Northwest are emphasized, the collection contains materials from throughout the world.
