rhizoid into the sporangium preceding the formation of the wall. 



"The cytology of [Endochytrium has been traced from the 

 zoospore through the formation of the zoosporangium and the 

 resting spore. The nucleus from the zoospore migrates into the 

 germ tube and at that point where migration stops the center 

 of organization of the thallus is established. The resting nuclei 

 possess a large ring-shaped nucleolus. The spindle is intranuclear 

 with central bodies appearing at the poles. A large nuclear cap 

 is associated with the zoospore nucleus. Cleavage of the spo- 

 rangium is by progressive furrowing to form the uninucleate 

 zoospores. 



"Germination of the resting spore is reported here for the first 

 time. On germinating it gives rise to a sporangium. The resting 

 spore is a prosporangium with one or more nuclei. 



"Michrochemical tests applied to the refractive substance 

 of the zoospores, sporangia and resting cells indicate that this 

 is a fat." 



The meeting adjourned at 5 : 00 p.m. After the meeting tea 

 was served in the mycology Laboratory.

Meeting of December 6, 1938 



The meeting of the Torrey Botanical Club held at the Ameri- 

 can Museum of Natural History on December 6 was called to 

 order by the President, Dr. Alfred Gunderson at 8:15 p.m. 

 Forty-two persons were present. 



Dr. William S. Thomas briefly described the memorial serv- 

 ice held on Long Mountain for the late Raymond H. Torrey. 



All business of the Club was omitted so that more time might 

 be devoted to the program of the evening which consisted of an 

 illustrated talk by Dr. Thomas on the "Edibility of Mush- 

 rooms." After discussing the historical aspect of mushrooms and 

 organic constituents the speaker pointed out that there is really 

 very little nutrient value in mushrooms since 88% of them is 

 water. Some vitamins are present. There are about 210 calories 

 in a pound of mushrooms. As various colored slides were shown 

 Dr. Thomas told how edible species can be distinguished from 

 poisonous types. If mushrooms turn blue when cut, bite the
