cut	IVL. Between cys-10 (28 to 37%) and fi (4 to 10%) (802; D.D. Perkins, unpublished data). Linkage to IR, shown in original cut strain HK53, was due to an unrecognized I;IV translocation (808). When an allelic cut point mutation (LLMI) became available, it was mapped in IV rather than in I and segregated independently of I markers (802). Sensitive to high osmotic pressure. Phenotype similar to that of os mutants. Scorable either by morphology or by failure to grow on agar containing 4% NaCl. Morphology approaches normal at high humidity (573). Allele HK53 is inseparable from T(I;IVL)HK53 (808).	IVL	B
psi-1	IVR. Right of the centromere (D.R. Stadler, A.M. Towe, and M. Loo, cited in reference 619). Left of T(ALS159) and pyr-1 (4%) (808, PB). Conidial germination and hyphal growth inhibited at 35°C but normal (or nearly so) at 20°C. Protein synthesis reduced after shift to restrictive temperature. Recessive in heterokaryons. (619) Scored as an irreparable heat- sensitive unmutant (see un).	IVR	B
