  1. Strains were cultivated for 13 days at RT on MEA and conidiophores were taken for microscopy from the outer white growth zone characterized by flocks of conidia. n = number of structures or cells analyzed. For counting spores per plate, five plates per strains and per medium were inoculated and spores were counted after fully growth of plates at RT
