 (exploration in compan}' with Dr. Jennison), pictures being shown of Solidcujo

Meeting of November 6, 1939 



The regtilar meeting of the Torrey Botanical Ckilj held on 

 November 6 at the American Museum of Natural History was 

 called to order at 8.30 by the President. 



Forty-seven persons were present. 



The following were elected to annual membership in the Club : 



Dr. Alphonse L. Heun, 3401 West Wisconsin Ave., Milwaukee, 

 Wis. ; Dr. B. W. Wells, Dept. of Bot., N. C. State College, Raleigh, 

 N. C. ; Dr. Ernst E. Naylor, N. Y. Bot. Card., Bronx Park, New^ 

 York; Dr. Paul A. Young, Tomato Disease Laboratory, Jackson- 

 ville, Texas; Dr. Virgene W. Kavanagh, N. Y. Bot. Card., Bronx 

 Park, New York ; Mr. Frederick Kavanagh, N. Y. Bot. Card., 

 Bronx Park, New York; Prof. Arthur W. Haupt, Dept. of Bot., 

 Univ. of Calif., Los Angeles, Calif., and Mr. Victor R. Larsen, 636 

 W. 174th St., New York. 



The resignation of Mr. Jonathan Gordon, 361 Sterling Place, 

 Brooklyn, New York, was accepted with regret. 



It was voted by the Club to have the annual meeting held on 

 January 9, 1940 instead of January 2 so that annual reports can 

 be completed more easily after the close of the Club year on De- 

 cember 31. 



The scientific program of the evening consisted of a lecture by 

 Dr. B. O. Dodge on Mendelism in Fungi. The speaker's abstract 

 follows : 



"In genetic studies of higher plants and animals the effects of factors of 

 inheritance are usually manifested in connection with diploid structures. In 

 the fungi most of the morphological features are found in connection with 

 haploid structures, so the effects of a single set of genes may be studied. 

 The bakery molds of the genus Neurospora are excellent material for genetic 

 studies. Lindegren was the first to point out that second division segregation 

 with the development of four genotypically different kinds of spores in an 

 ascus were measures of crossing-over percentages. Those who have w'orked 

 genetically with smuts and mushrooms have assumed that disjunction of 

 homologous chromosomes may occur either in the first or second division to 

 account for the four types of spores developed at reduction of the zygote
