SUMMARY In liquid cultures Cercosporella herpotrichoides utilized both organic and inorganic sources of nitrogen and showed an absolute requirement for thiamin. On nutrient agar and through sterilized straw, C. herpotrichoides grew more slowly than other facultative fungal parasites of cereal roots and stem‐bases. The competitive saprophytic ability of C. herpotrichoides was found to be very limited. The observation that saprophytic colonization of straw tissue by Ophiobolus graminis declined as invasion progressed inwards was confirmed and found to occur also with C. herpotrichoides and Helminthosporium sativum but not with Fusarium culmorum. It is concluded that C. herpotrichoides exhibits a low competitive saprophytic ability and is therefore unlikely to colonize straw in the soil.
