Locus	Cultural Requirements	Link Group	Type
ff-3	IR. Right of os-1 (3%) (193).Defective in protoperithecial production. Abnormal morphology. Found in strain T22, which also contains ty-3 and ty-4. Not alielic to ty-3 or T. (193, 460) (Possible allele of so?)	IR	B
ty-3(22)	IIIR. Near the centromere; left of ad-4 (W.L. Chan, Ph.D. thesis, University of Malaya, Kuala Lumpur, 1977, cited in reference 460). Not allelic with T or ff-3(193; N.H. Horowitz and H. Macleod, cited in reference 332). Tyrosinase repressed. Uninducible by protein synthesis inhibitors, e.g., cycloheximide, in vegetative culture (322, 460; N.H. Horowitz and H. Macleod, cited in reference 332). Originally reported to be female sterile and morphologically abnormal; subsequently, these properties were shown due to a second, nonallelic mutation, ff-3. The ty-3 single mutant is female fertile and morphologically normal (193). Score by color reaction with DL-DOPA as the substrate (475, 477). The original strain containing both ty-3 and ff-3 is called T22; it also contained ty-4, q.v.	IIIR	B
