Schizophyllum commune
was investigated by use of manometric techniques and specific respiratory poisons. Basal respiration was stimulated markedly by the uncoupling agent 2,4-dinitrophenol. This effect was pH-dependent and was sensitive to antimycin A. A positive periodic acid-Schiff reaction and a respiratory quotient (CO

) of near unity pointed to carbohydrate as the endogenous substrate. Oxygen consumption was increased by sucrose, certain hexoses,
d
-xylose, acetate, and ethanol. Oxidative assimilation was evident with
d
-glucose and acetate. Glucose oxidation was inhibited by cyanide, azide, antimycin A, Atabrine, and phenylmercuric acetate. These data implicate cytochrome oxidase,

c
-type cytochromes, flavoprotein, and essential sulfhydryl groups in basidiospore respiration.
