Specimens examined: Unknown, on Sachs rice-straw-agar medium, M. Tsuda, BPI617624. USA, California, Glenn County, 3 Jun. 2011, J. Oster, RUTPPM69, RYTPPM70, RYTPPM71.<\/span><\/p>\n

Hosts\/substrates: On stems of Oryza<\/em> as well as Echinochloa<\/em> and Zizania<\/em> (Poaceae<\/em>).<\/span><\/p>\n

Distribution: Worldwide.<\/span><\/p>\n

Notes: Cattaneo (1877) first named the sclerotial state of this species as Sclerotium oryzae<\/em>. Hara (1939) formerly introduced Nakataea sigmoidea<\/em> (synonym Helminthosporium sigmoideum<\/em>) for the conidial state while the ascosporic state was described as Magnaporthe salvinii<\/em> (synonym Leptosphaeria salvinii<\/em>) by Krause and Webster (1972). Luo and Zhang (2013) regarded Nakataea oryzae<\/em> for this species using the oldest legitimate generic name and species. It causes stem rot disease of Oryza<\/em> and has also been reported from Zizania<\/em> and other Poaceae<\/em>.<\/span><\/p>\n
