As of Oct 2017, CUP is without a Collections Manager/Curator. At this time our ability to fulfill loan requests and respond to correspondence will be much slower than you have come to expect. We hope to fill the position soon. Please address email for CUP to


Scott LaGreca in 2017Dr. Scott LaGreca left his job as CUP Curator in October 2017 to become Curator of Lichens at Duke University. We are excited for him, though after 6 years of truly outstanding work shepherding CUP, we are very sad to see him go. We already miss his kindness, cleverness, and wit, and his ability to marshall resources and keep multiple projects running smoothly. His lichenology expertise made him a sought-after teacher; he remains Editor of the journal Evansia; and as co-leader of the recent SIPS Bioblitz, Scott's influence at Cornell has extended well beyond this herbarium. Here you see Scott issuing the Cornell Hoot with his usual verve and energy.

Prof. Korf in 1972CUP's Director Emeritus, Professor Richard P. Korf, passed away in August 2016 at the age of 91. Dr. Korf is remembered in this Cornell Chronicle article. Friends may choose to remember him via a donation to Cornell's Richard P. Korf Graduate Excellence Fund.

Work is progressing on our effort to digitize all data about CUP's specimens, and make it available via mycoportal and lichenportal. There you can also find data from our earlier project on the extensive collections of G.F. Atkinson (1854-1918), an influential Cornell mycologist. Learn more about him on our Atkinson website. We appreciate support from the National Science Foundation for these key projects.


The Cornell Plant Pathology Herbarium (CUP) is a large research collection of preserved fungi and other organisms that cause plant diseases. CUP is the fourth or fifth largest mycological herbarium in North America. We hold about 400,000 fungus and plant disease specimens, including over 7000 type specimens, each the first of its kind to be described and named. The CUP Photograph Collection includes about 60,000 historical scientific photographs of mushrooms, agricultural practices, plant diseases, and portraits.

Our collections have moved into a newly-renovated, permanent facility on Game Farm Road, at the eastern edge of the Cornell campus. Our new home provides excellent space for our collections and for visitors. Please note that our mailing address has not changed.
