Temperature responses of mycelial growth of Sclerotinia sp. collected in Cerrado on P D A were similar to Japanese isolate of S. sclerotiorum S B-1 but not to that of S. trifoliorum Y W-4. In dual culture the mycelia of isolates in Cerrado and S. sclerotiorum S B-1 intermingled freely without the formation of a brown zone in the regions association on P D A medium, being in good agreement with Wong and Willets` reaction type (i). On the other hand, a white zone could be seen between mycelia of isolates in Cerrado and S. trifoliorum Y W-4. As a result, all the isolates of Sclerotinia sp. collected in Cerrado region should be identified as Sclerotinia sclerotiorum.  aCerrado  aDoença de Planta  aFungo  aSclerotinia Sclerotiorum  aFungal diseases  aPlant diseases1 aMITSUEDA, T.1 aCHARCHAR, M.
