Description Sporeballs of Tolyposporiumpenicillariae varied from circular to near-polyhedral and measured 42–325 × 50–175 μm. The number of teliospores aggregated in balls varied from 200 to 1400. Teliospores were mostly circular and measured 7–12 μm diam. Maximum germination of teliospores aggregated in balls occurred at 30 °C and different patterns of germination were observed. Large variability was observed in cultural characters of the pathogen grown on different media. The fungus grew well within 3–5 days on potato or carrot agar at 35°. Growth of the fungus remained purely sporidial even after repeated subculturing. Sporidia were borne on promycelia, laterally and/or terminally, and these reproduced by budding in chains. Sporidia were spindle-shaped and varied in length from 8 to 25 μm. Individual separated teliospores seldom germinated. The use of sporidial inoculum in screening for smut resistance in pearl millet is discussed.
