Abstract
All eight genera of thermophilous fungi studied could grow on agar with any of the carbon and nitrogen compounds incorporated. The colonies that developed on carboxymethylcellulose-incorporated agar were sparse, straggly and poorly sporulating or asporogenous. Except for Thermomyces lanuginosus Tsik. the rest of the fungi showed dense mycelial development and sporulation with casein hydrolysate. Urea was a poor nitrogen source for growth and sporulation of thermophilous fungi. More species of thermophilous fungi showed dense mycelial development and sporulation with nitrate-nitrogen than with ammonium-nitrogen.
