Postmarked Jan 14 '75
Dear David, It's a long time ago and I'm not perfectly clear on all points. When I came to Cal Tech in 28 Morgan was himself disserting Neurospora. But his procedures resulted in contamination with P[ . . . ]. It stands to reason, and I believe I remember, that he was using sitophila because these were the cultures that Dodge had published on. I did some work with the culture that Morgan was using, determining the temperatures for germination. I worked on a micromanipulator and the first things that I did involved hybrids between (I believe) sitophila and tetrasperma. The results were impossible for me to interpret at that time. Before that I had done some work on seg g plus/minus in tetra. But I can't remember where I got the cultures. I spent the summer of '30 in N.Y with Dodge. He always wanted more work on tetrasperma and was disappointed that I couldn't see it as useful.
I must have got the ecursa [?] culture from him that summer in N.Y.
The story of how Dodge got his cultures came to me from Thom. Thom was working on the imperfect stage at the U.SDA. He published a paper showing how well it

managed without a sexual phase. Shear (his boss) saw protheria in his cultures and turned them over to one of the women in the dept. She was too slow for him and he gave them to Dodge. When Shear and Dodge published the sexual cycle, Thom was furious. He told me he never would use the word "Neurospora".
Crassa just seemed to grow better than sitophila. I stayed with it except for one diversion mentioned in my paper on Bisexual Self-Sterile Heterokaryons. This time Dodge wanted to have some fun confusing me. He sent me a culture and asked me to tell him if it was his A or B; according to my plus or minus. I didn't want to use A and B because this procedure implied 2 loci. He couldn't understand my reluctance. He refused to accept the crossing over explanation Med Div Seg until the recursion [?] meeting of 1939, 7 years after the first paper.
Regards
Carl
