The Oregon State University Herbarium (OSC) houses over 550,000 vascular plant, bryophyte, algal, and 200,000 fungal collections. The collections are worldwide in scope, with a focus on the state of Oregon and the Pacific Northwest.

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 increased in size and became a significant research resource for studies of the fungi of the Pacific Northwest. I am the current curator and my focus is on increasing representation of Pacific NorthWest fungal diversity in the OSC via the OR Mycoflora Project, and accessioning the ~35,000 isolate truffle collection of Drs. Jim Trappe and Mike Castellano.
