PROCEEDINGS OF THE CLUB 

 Meeting of May 18, 1932 



The meeting was called to order at the Boyce Thompson 

 Institute for Plant Research at 3:30 P.M. by President Sinnott. 

 Those who wished to see the laboratories and research work at 

 the Institute met at 2 P.M. There were 53 members present. 



Miss Caroline C. Haynes donated $100.00 to the club. A 

 motion was made and seconded that the Secretary send Miss 

 Haynes a letter of thanks. 



The following people were unanimously elected to member- 

 ship in the club: Miss Clara M. Elsaesser, Paterson, New Jer- 

 sey; Dr. Carl C. Lindegren, Biology Dept., California Inst. 

 Technology, Pasadena, California; Miss Edna Elmore Milli- 

 man, Paterson, New Jersey; Mr. John Landon Rodda, Palmer- 

 ton, Pa.; Mr. John A. Small, N. J. College for Women, New 

 Brunswick, New Jersey. 



Dr. B. O. Dodge of The New York Botanical Garden gave a 

 very interesting talk on "The Sexual and Non-Sexual Function 

 of the Microconidia of Neurospora" which is published in full 

 in the June Bulletin of the Torrey Botanical Club. 



Dr. F. E. Denny of the Boyce Thompson Institute for Plant 

 Research gave an interesting talk on "The Oxygen Require- 

 ments of the Bakery Mold, Neurospora, for Mycelial Growth 

 and Perithecium Formation," as follows: 



Because of the observation of B. O. Dodge that with 

 Neurospora sitophila the two mycelia of opposite sex are in- 

 capable of forming perethecia unless they meet in the presence 

 of air, experiments were undertaken to determine the con- 

 centration of oxygen necessary to permit these fruiting bodies to 

 form. At concentrations of oxygen less than 2 per cent, it was 

 found that perethecia formed very slowly, and at less than 0.5 

 per cent they did not form at all, at least within one month. 

 The oxygen requirement for the growth of the mycelium was 

 found to be much lower, good growth occurring at 0.3 per cent 

 O2, and visible growth at concentrations of 0.05 per cent or 

 even lower. The apparatus necessary to produce and maintain 

 these concentrations of 2 was described.
