Abstract

Pyhium sp. was isolated from spinach seedlings, severely affected with damping -off during midsummer. Isolated Pythium sp. grew well at high temperature, and its optimum temperature was 38C. The fungus was morphologically distinguishable from Pythium aphanidermatum in the size of oogonium and antheridium formation. According to the key proposed by Waterhouse (1967), it was identified as Pythium butleri Subramaniam.
