\n\u00a0 \u00a0 Conidiophores solitary, erect, straight or curved, unbranched or sparsely branched, hyaline, smooth. Conidiogenous cells phialidic, erect, terminal or intercalary, hyaline, smooth, 7\u201320 \u00d7 2\u20136 \u00b5m, 2\u20133.5 \u00b5m, with a cylindrical collarette, 1\u20133 \u00d7 1\u20132 \u00b5m.

Material examined: China, Hong Kong, on Oryza sativa<\/em>, 14 Apr. 1975, S. Jordan, BPI 626742. USA, Arkansas, Ahuyna, on Oryza sativa<\/em>, 8 Oct. 1928, E.C. Zieller, BPI 626741.<\/span><\/p>\n

Pathogenicity: Gaeumannomyces oryzinus<\/em> was reported from rooting roots and culms mainly on rice (Oryza sativa)<\/em>, but was also found on Bermuda grass (Cynodon<\/em> sp.) as well.<\/span><\/p>\n
