The species of Cercospora described hierein hias beeni collected frequently on Leucoth5e Catesbaei Gray in nurseries and ornamiental plantings in New Jersey and has also been found oni Lonig Island by H. H. Whetzel. An examiination of either type or cotype specimens of Cercosporae described on Ericaceous plants shows this to be specifically distinct. The more important differences follow. The Cercospora on Leuicoth5e differs from C. gay-lussaci Speg. and C. Kalmiuae Ellis & Ev. in its narrower conidia; from C. Oxydenidril Tracy & Earle, C. Kalinilae, C. sparsa Cooke and C.

Also its conidiophores are narrower than those of C. Gauitheriac and shiorter than those of C. molleriana. The following name is proposed:
