Richard C. Summerbell (born 29 June 1956) is a Canadian mycologist, author and award-winning songwriter. He was editor in chief of an international scientific journal in mycology from 2000 to 2004. In the 1970s and 80s, he was a gay activist and an early commentator on (then) controversial topics such as AIDS and promiscuity and attitudes to homosexuality in organized religion. Born in Brooks, Alberta, Summerbell trained as a botanist, receiving his master's degree from the University of British Columbia and his doctorate degree from the University of Toronto. He has lived with his partner, Ross Fraser, since 1978 and currently resides in Toronto, Canada. Research in Mycology Summerbell has published over 150 peer-reviewed papers in mycology, botany and bacteriology, including research papers in Nature and Philosophical Transactions of the Royal Society. Much of the research explores opportunistic fungal pathogens—those that grow on (and at the expense of) humans and animals—and the unique ways in which these organisms exploit their environments. These environments are diverse. They include biofilms in hospital plumbing that harbour fungal pathogens which attack patients hospitalized for leukemia or major organ transplants. They also include waterfront vacation properties on streams, lakes or rivers that infect otherwise healthy visitors with the often deadly disease blastomycosis. His most cited works are on the fungi that cause human skin diseases (dermatophytes) and nail infections (onychomycosis). , his 1989 paper on onychomycosis is the most-cited original research paper published in the over 50-year history of the journal Mycoses. Summerbell spent a decade as the Chief of Medical Mycology at the Ontario Ministry of Health Public Health Lab in Toronto, followed by 6 years as senior scientist at the Centraalbureau voor Schimmelcultures, a mycological institute and branch of the Royal Netherlands Academy of Arts and Sciences in Utrecht. He was editor-in-chief of the international scientific journal Medical Mycology from 2000 to 2004. Since 2008, he has been a faculty member of the University of Toronto Dalla Lana School of Public Health and research director of Sporometrics, a Toronto-based microbiological testing company. Summerbell has co-authored two textbooks in medical mycology, Identifying Filamentous Fungi (simultaneously published in French as Champignons Filamenteux D'Intérêt Medical) and Laboratory Handbook of Dermatophytes. Species (co-)described include: Arachnomyces kanei (asexual state Onychocola kanei), an invader of human nails Phaeoacremonium krajdenii, a cause of subcutaneous infection of humans Phaeoacremonium alvesii, a cause of subcutaneous infection of humans Phaeoacremonium amstelodamense, a cause
