Curvularia defined by the type species C. lunata (Wakker) Boedijn. Curvularia lunata appears as shiny velvety-black, fluffy growth on the colony surface. C. lunata is distinguished by septate, dematiaceous hyphae producing brown, geniculate conidiophores. The poroconidia are curved slightly to distinctly, transversely septate, with an expanded third cell from the pore end of the conidium. Curvularia can be easily distinguished from Bipolaris and Drechslera spp. since the conidia are non-distoseptate, that is, septate from edge to edge of the conidial wall. The teleomorphic state of Curvularia lunata is Cochliobolus lunatus (Fam. Pleosporaceae, Ord. Pleosporales, Cla. Loculoascomycetes, Phy. Ascomycota).
