Description: | On grass leaf: Thallus intramaterial and extramaterial, eucarpic, polycentric. Rhizomycelium extensive, delicate, richly branched, with numerous fusiform, spindle-shaped, septate turbinate organs. Zoosporangium terminal or intercalary, apophysate or nonapophysate, spherical or ovoid, 10-32.5 μm diam., with one, occasionally two, short discharge tubes. Zoospore spherical, 5-7.7 μm diam., with a golden-brown globule; emerging in a gelatinous vesicle at the orifice, quiescent about 20 seconds previous to escaping from the vesicle and swimming away.On 1/4 YpSs agar: Zoospore germinates into a polycentric thallus. Rhizomycelial growth on agar, mature zoosporangia at center of colony. Resting spore not observed. Center of colony yellowish-orange, periphery white. | |||
