dn	IVR. Right of pyr-2 (4%). Linked to mat (1%) (692, 812).Abnormal morphology, slower than normal growth, producing grey patches of microconidia in addition to macroconidia (692). When in combination with fl, microconidia are produced exclusively and in abundance, as in the double mutant pe fl. The double mutant fl;dn is fully fertile in homozygous crosses (811) and for this reason may be preferred to pe fl as a microconidating strain. Microconidia from fl;dnare less viable, however (454).
