The aim of this work was to characterize Glomerella cingulata f. sp. phaseoli strains for mycelial growth, perithecia formation and ascospore dimorphism. Four strains were evaluated in common bean leaves and PDA media, with and without photoperiod. Length of the wild and mutant strains of ascospores was determined. There was asignificant difference for mycelial growth and ascospore size. This is the first time that ascospore dimorphism has been reported in Glomerella cingulata f. sp. phaseoli.
