" The present investigation reveals in the Cyanophyceae a 

 series of nuclear structures beginning with a very simple form of 

 nucleus scarcely differentiated from the surrounding cytoplasm 

 and dividing by simple direct division. From this we pass by 

 very gradual steps to a highly differentiated form of nucleus 

 which in dividing shows a primitive type of mitosis, and in 

 structure approximates the nucleus of the Chloroph}-ceae and 

 the higher plants." 



" In this group of plants the transmission of hereditary 

 qualities seems to be accomplished with the greatest precision, 

 without the complicated machinery of mitosis. In this connec- 

 tion it may be noted that the lack of sexuality seems in no wise 

 to affect the amount of variation, which is quite the same as in 

 -groups where sexual reproduction occurs."

PROCEEDINGS OF THE CLUB 



March 27, 1907 



The Club met at the museum building of the New York Bo- 

 tanical Garden at 3:30 p. ^L Thirteen persons were present. 



The death of Dr. Otto Kuntze, at San Remo, Italy, on January 

 28, 1907, was reported, and the resignation of Professor George 

 Macloskie was presented and accepted. 



The following scientific program was presented : 



" Some Lactarii of Windham County, Vermont," by Miss Ger- 

 trude S. Burlingham : 



The rugged and w^ooded character of Vermont makes the re- 

 gion especially favorable for the growth of the fleshy fungi. But 

 the only field work in the state on this group, of which we have 

 published results, is that of Charles C. Frost (1805- 1880), who 

 collected in the vicinity of Brattleboro. Frost was a shoemaker 

 in Brattleboro, and is commonly reported to have begun his bot- 

 anical tramps as an antidote for dyspepsia. In 1875 he cooper- 

 ated with Tuckerman in a " Catalogue of plants growing without 

 cultivation within thirty miles of Amherst College," and it is 

 probable that most of the fungi listed were collected by Frost in 

 Vermont.
