title: Nematospora sinecauda sp. nov., a yeast pathogen of mustard seeds.
abstract: An undescribed yeast species was recovered from oriental (Brassica juncea) and yellow (B. hirta) mustard seeds. The new species most closely resembled Nematospora coryli but its asci were rarely cylindrical. The asci and ascospores of N. sinecauda were smaller and the spores did not possess a whip-like appendage. During germination a sprout cell formed first on the smooth anterior surface of the spore above the median ridge. The posterior region of the spore was decorated with interrupted concentric ridges. A description of the new species is given.
