Abstract Bimuria novae-zelandiae gen. et sp. nov. (Ascomycotina, Pleosporales) is described from an isolate obtained from soil in a barley field in the Wairarapa district of the North Island, New Zealand. It is distinguished by a very thin peridium,-which is hyaline at first, and mainly 2-spored asci the endoascus of which deliquesces to liberate the ascospores. The ascospores are muriform, dark brown with pale end cells, minutely verrucose, and lack a gelatinous sheath. Its cultural characteristics are outlined and scanning electron micrographs of the ascospores are included. Bimuria is compared with some superficially similar or allied genera and is considered to be most closely related to Pleospora subgen. Montagnu/a, from which it differs in several important characters.
