{{Short description|Canadian mycologist (1901-1991)}} '''Kenneth A. Harrison''' (1901 – November 5, 1991) was a Canadian mycologist. He was for many years a plant pathologist at what is now the Atlantic Food and Horticulture Research Centre in Nova Scotia. After retirement, he contributed to the taxonomy of the Agaricomycotina, particularly the tooth fungi of the families Hydnaceae and Bankeraceae, in which he described several new species.

==Early life and career== Originally from New Brunswick, Harrison graduated from Nova Scotia Agricultural College in 1922, and, in 1924, from the Ontario Agricultural College with a B.Sc. in agriculture.<ref name="BNSN 1991"/> He earned an MSc in plant pathology from Macdonald Campus of McGill University a year later. A doctoral degree he started at the University of Toronto in 1929 was abandoned due to the Great Depression.<ref name="BNSN 1991"/> He established a herbarium of mycological specimens where he was employed for many years at the Kentville Research Station (now the Atlantic Food and Horticulture Research Centre); most of his collections are now housed at the Canadian National Mycological Herbarium.<ref name="Estey 1994"/> His early research concerned the fungal infestation of plants, such as that of ''Colletotrichum lindemuthianum'' on beans (''Phaseolus''). Working with John Frederick DeWitt Hockey, they made many contributions to the control and prevention of diseases of horticultural crops. They were among the first to use the sticky slide spore trap to estimate the densities of fungal spores.<ref name="Obit"/>

==Post-retirement activities== After his retirement in 1966, Harrison began studying the mushroom-producing species of the Agaricomycotina more avidly. Collections forays throughout Nova Scotia, in the Great Smoky Mountains, New Mexico, the Upper Peninsula of Michigan, and the Pacific Northwest led to him describing several new species in the genera ''Steccherinum'', and tooth fungi in ''Hydnellum'', ''Sarcodon'', ''Phellodon''. Harrison died in Kentville, Nova Scotia, in 1991.<ref name="Obit"/> The Department of Biology at Acadia University has a mycology laboratory named in his honour.<ref name="BNSN 1991"/>

==Eponymous species== The tooth fungus ''Sarcodon harrisonii'' was named in his honor by Richard Baird, who noted "Dr. Kenneth Harrison the North American expert on the stipitate hydnums. From his publications, professional and amateur mycologists can more easily identify the taxa of the group".<ref name="Baird 1985"/> Other fungi named after Harrison include: *''Boletus harrisonii'' A.H. Sm. & Thiers<ref name="Smith 1971"/> *''Ramaria harrisonii'' R.H. Petersen 1986<ref name="Petersen 1986"/> *''Psathyrella harrisonii'' A.H. Sm. 1972<ref name="Smith 1972"/> *''Cortinarius harrisonii'' Ammirati, Niskanen & Liimat. 2013<ref name="Niskanen 2013"/>
