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". Other fungi named after Harrison include: *'' Boletus harrisonii'' A.H. Sm. & Thiers *'' Ramaria harrisonii'' R.H. Petersen 1986 *'' Psathyrella harrisonii'' A.H. Sm. 1972 *'' Cortinarius harrisonii'' Ammirati, Niskanen & Liimat. 2013
