Clark Thomas Rogerson (born 1918) is a mycologist, editor, educator, and authority on Hypocrealean fungi. Born in Ogden, Utah Dr. Rogerson gained his B.S. (1940) at Utah State University and his Ph.D. (1950) at Cornell University where he studied under Harry M. Fitzpatrick. During his years at Cornell he was a graduate teaching assistant in mycology in the Department of Plant Pathology. Upon graduation he was appointed to the faculty of Kansas State University (1950-57) where he was associated with the Kansas Agricultural Experiment Station. It was here that he began publication on topics in plant pathology, including the diseases of grasses.

In 1958 Dr. Rogerson began his career with the New York Botanical Garden, first as Curator of Cryptogamic Botany (1958-67) then as Senior Curator (1967-89) and Senior Curator Emeritus (1990-present). At the Garden he continued his study and publication on the taxonomy of the Ascomycetes, especially of Hypomyces, a genus of fungi that parasitize other fungi. Dr. Rogerson has been an enthusiastic fieldworker and has collected fungi throughout the United States, notably in Utah and New York. During World War II he collected in the Philippine and Solomon Islands. He has been a guiding presence at mycological forays for many years and a tireless educator of amateurs interested in the world of fungi. He has held faculty appointments at Columbia University and at Lehman College (CUNY).

At the Garden Dr. Rogerson has had a distinguished career as editor of several scientific publications, notably of Mycologia, serving as Managing Editor (1958-89) and Editor-in-Chief (1960-65). He has also served as editor of the Memoirs of the New York Botanical Garden (1963-88), North American Flora (1963-88), and Flora Neotropica (1969-83). He has served as historian of the Mycological Society of America (1960-90) and the Torrey Botanical Club (1968-89). He was MSA president in 1969. He has also been a fellow of the American Association for the Advancement of Science and life member of the North American Mycological Association, Bergen Swamp Preservation Society, and Utah Academy of Sciences. In 1984 the Garden presented him its Distinguished Service Award. Dr. Rogerson currently resides in Utah.


The Clark T. Rogerson collection consists of correspondence, notebooks, research papers, manuscripts and typescripts, specimen material, and graphic material including color slides, photographs, negatives, and illustrations of fungi. The collection covers his career as a mycologist at Cornell University, Kansas State University, and the Garden. There are significant holdings relating to his editorship of the journal Mycologia and other scientific publications.
