Critical Notes on Some Plant Rusts: III

Abstract

A critical study of certain rust genera is presented. New combinations suggested include Chrysomyxa simplex (Coleopuccinia simplex Diet. and Coleopucciniella simplex (Diet.) Hara); Stereostratum lagerhamianus (Cleptomyces lagerEamianus (Diet.) Arth); Chrysocelis coaetaneum (Desmotelium coaetaneum Syd. and Chaconia coaetaneum (Syd. (Cumm.) Kuehneola flacourtiae (Catenulopsora flacecourtiae Mundk.); Kuehneola vitis (Catenulopsora vitis (Butl.) Mundk.); Kuehneola zizyphi (Catenulopsora grewiae Thirum. and Mundk.). Kuehneola grewiae (Catenulopsora grewiae Thirum. and Mundk.). The generic description emendations of Northoravenelia, Endophylloides and Asthomycetella are listed and cited. The use of subcuticular and subepidermal pycnia to differentiate genera is discussed and considered valid.
