An isolate of Verticillium albo-atrum and V. dahliae was grown on synthetic liquid medium containing trehalose and polyols as the carbon sources. Periodic determination of the mycelial dry weight showed that trehalose and glycerol were the best sources. Verticillium albo-atrum grew better than V. dahliae on d-mannitol, d-glucitol, and ribitol. Good growth following a long lag period occurred with erythritol. Both species grew poorly on galactitol, d-xylitol, d- and l-arabitol, and i-inositol. Verticillium dahliae produced few or no microsclerotia on d-mannitol, d-glucitol, and erythritol.
