    Abstract

    THE issue for June 1948 of the Proceedings of the Indian Academy of Sciences (27, B, No. 6) contains two contributions to the phytopathology of southern India. M. S. Balakrishnan (pp. 161-173) describes a new species of Pythium (P. indicum), causing a fruit rot of Hibiscus esculentus. The fungus has filamentous sporangia, the typical sexual reproduction of Pythium, and has a wide host-range, including maize and Petunia. K. V. Ramakrishnan (pp. 174-193) has studied isolations of Piricularia from four liost species —Oryza sativa, Eleusine coracana, Setaria italica and Digitaria marginata. No difference in morphology has been found between the four isolates ; but their physiology varies somewhat, particularly in the width of host-range, the most favoured sources of carbon and nitrogen, the optimum temperature, and the enzyme status.
