Abstract
SUMMARY The perfect state of Helminthosporium coicis, causing leaf-blight disease of Coix species, was produced on Sachs agar medium with rice straw by the same method described in previous papers on perfect state formation of H. orysae and Cochliobolus miyabeanus. Morphologically, the perfect state is somewhat different from Cochliobolus, especially in the existence of basal columnar stromata and of ascospore arrangement with parallel to loose coiling in the ascus. Thus a new genus, Pseudocochliobolus, is described. Pseudocochliobolus nisikadoi is designated as type species of the new genus.
