The teliospores of Sorosporium paspali-thunbergii were observed in spore balls of 17-34 x 42-57 µ. The individual teliospores are globose, sub-globose, angular in shape and yellowish brown to dark brown in colour. The size of teliospore ranged 6-13 x 4-19 µ. Maximum teliospore germination was observed in 2 % glucose solution over 1 % glucose solution and tap water. Maximum radial growth was observed in Potato Dextrose Agar medium followed by Oat Meal Agar medium, Corn Meal Agar medium and Czapek’s dox Agar medium. Potato Dextrose Agar medium produced white mycelial colony, submerged and regular fast growth and no pigmentation. White to yellow colony, Sub merged, regular moderate growth and no pigmentation were observed in Oat meal agar medium. Light pink pigmentation, white to light pink mycelial colony and cottony, regular moderate growth were observed in Czapek’s dox Agar medium. In Corn meal agar medium was recorded off white colour mycelial colony, cottony, regular moderate growth and no pigmentation. Storage medium and storage period were also observed to influence the viability of teliospores. Highest germination was recorded in teliospores stored in paper bags at 40 C. Reduction in longevity of teliospores ranged from 24.6 to 44.6 % in different storage medium over a period of 30 to 105 days.
