✦ Synopsis
During screening ofFusarium Lk. ex Fr. strains for antibiotic production, we observed a peculiar conidial swelling of Penicillium digitatum Sacc. strain NRRL 1202 when this sensitive fungus was grown in the presence of methanol extracts of Fusarium roseum Lk. 'Acuminatum' strain NRRL 6227 cultures. In an expanded study to determine the prevalence of a 'swelling factor' among Fusarium species, 23 of 132 strains produced an antibiotic that caused P. digitatum conidia to swell. Eighteen of the producing fungi belonged to the species F. tricinctum (Cda.) Sacc., two were identified as F. roseum 'Acuminatum', and one strain each was identified as F. roseum 'Sambucinum', F. roseum 'Equiseti' and F. graminearum Schwabe. These data indicate that production of an antibiotic that causes P. digitatum conidia to swell is not unique to only a few Fusarium cultures.
