Notes on Seed-Borne Fungi: Iii. Curvularia

In the examination of agricultural seeds for the presence of seed-borne fungi, five species of Curvularia have been isolated. Three species, C. geniculata (Tr. & Earle) Boedijn, C. inaequalis (Shear) Boed., and C. Trifolii (Kauffm.) Boed., have been identified by comparison with types. Two species, C. lunata (Wakker) Boed., and C. pallescens Boed., have been provisionally identified from the literature. The types of four North American species, C. geniculata (Tr. & Earle) Boed. (Helminthosporium geniculatum Tr. & Earle), C. inaequalis (Shear) Boed. (H. inaequalis Shear), C. Trifolii (Kauffm.) Boed. (Brachysporium Trifolii Kauffm.), and C. falcata (Tehon) Boed. (Acrothecium falcatum Tehon), have been examined. Helminthosporium Cymbopogi C. W. Dodge belongs to this genus and is transferred here as Curvularia Cymbopogi (C. W. Dodge) n. comb. The species isolated from seeds do not appear to be of serious pathological significance.
