✦ Synopsis

Temperature and p H significantly affect the growth and oospore production of the test fungi. The optimum temperature for mycelial production was nearly the same on both solid and liquid media. H-ion concentration has milder effect than temperature. The optimum temperature and p H value for oospore production agree remarkably with their respective8 for growth.

There is no doubt that environmental conditions exerts a profound effect upon growth and reproduction of microorganisms. The fungi as a large group of these organisms play an important role in the formation and destruction of numerous natural products in soil and water. Meagre information is available regarding theeffect of certain environmental factors such as temperature, pH, oxygen, moisture, and carbon source on the growth and reproduction of soil-borne
