Locus	Cultural Requirements	Link Group	Type
Fsp-1	IIR. Right of pe (4%) (D.D. Perkins, unpublished data).Some of the asci contain four large ascospores rather than the normal eight. In these asci, ascospores are formed at the four-nucleate stage after meiosis II. Dominant, with variable penetrance depending on genetic background. Ascospores from four-spored asci produce homokaryotic cultures. Rarely, three-spored or two- spored asci are formed, and these include some heterokaryotic ascospores. One postmeiotic mitosis is omitted in the four- and three-spored asci, and two divisions are omitted in the two-spored asci. Vegetative morphology is normal. (856) Used in the study of Sk (Spore killer) (857). The cytological basis of Fsp-1 is distinct from that in N. tetrasperma. For a description of a dominant eight-spored mutant of N. tetraspermasee reference 129.	IIR	B
