 One author regarded "C. dentatus" as a synonym of "Coccomyces coronatus", although later authors have treated them separately.In 1923, Carlos Luigi Spegazzini tentatively reported the presence of "C. dentatus" on fallen "Nothofagus" leaves in Tierra del Fuego (southern South America); this species was later identified as a distinct species, "C. australis".In 1982, Enrique Descals described an aquatic hyphomycete "Tricladiopsis flagelliformis" growing from submerged leaves found in the shoreline of Windermere (Cumbria, England), which he tentatively assigned as the anamorph state of "Coccomyces dentatus".
