History of the Herbarium: The mycological herbarium is dominated by collections of regional plant pathogens and the conspicuous fleshy fungi. Under the stewardship of Helen M. Gilkey, the scientific importance of the collection grew. Her own specialty, the hypogeous fungi, are especially well represented. Her successor William C. Denison, expanded the collections of discomycetes and lichenized fungi. James M. Trappe, together with his students and associates, has established OSU as a world center for the taxonomic study of mycorrhizal fungi. The mycological herbarium is the internationally recognized central repository for type specimens of vesicular arbuscular mycorrhizae. Under the curation of Dr. Joey Spatafora, the mycological collection has increased in size and has become a significant research resource for studies of the fungi of the Pacific Northwest. I will become the next fungal curator when I start in January!
