352 The Ohio Naturalist. [Vol. XI, No. 7, 



nonseptate, smooth or minutely roughened at the base, apex 

 simply uncinate; asci 5-8, broadly ovate; spores 4-6. On leaves of 

 Mortis rubra. Oxford, O. October, 1909. 



These species may be distinguished from other Ohio species by 

 the narrow, colorless appendages and the 4-7 spored asci; from 

 each other, by the number and length of the appendages. 



MEETINGS OF THE BIOLOGICAL CLUB. 



Orton Hall, Jan. IGth, 1911. 



The meeting was called to order by the president, Dr. Dach- 

 nowski. The minutes were read and approved. Dr. William E. 

 Henderson then favored the society with an interesting and 

 instructive address on "Some Recent Theories of Solution and 

 Osmosis and Their Biological vSignificance. He gave an exposi- 

 tion of the kinetic theory and contrasted it with the recent solu- 

 tion theory of Kahlenberg. The importance of possessing true 

 and definite conceptions concerning osmotic phenomena when 

 attacking physiological problems, was made very evident by 

 the speaker. 



After a discussion of the address, the society listened to a 

 report of the American Association meeting at Minneapolis, by 

 Prof. Barrows and a report of the meeting of American physiol- 

 ogists at Yale University by Prof. Seymour. In the short bus- 

 iness meeting Prof. T. M. Hills was elected a member of the 

 society. No further business being presented, the society 

 adjourned. 



Orton Hall, Feb. 13th, 1911. 



The president. Dr. Dachnowski, called the meeting to order. 

 The minutes were read and approved. The first of a series of 

 papers on the history of biology was presented by B. W. Wells. 

 The early history of biological science was covered down to the 

 time of Galen. Mr. B. B. Fulton gave a description of Hocking 

 County as a collecting ground, setting forth the wild and primitive 

 conditions that still obtain in this locality. Mr. J. L. King pre- 

 sented a paper on "Insect Photography," in which he outlined the 

 essentials necessary for success in this special line of work and 

 discussed the methods used by experiment stations in illustrating 

 their entomological bulletins. A number of lantern slides, made 

 from photographs by the speaker, were of much interest. 



A short business meeting was held in which Mr. A. R. Shadle 

 was elected a member of the clul), after which the society 

 adjourned. 



Bertram W. Wells, Secretary.
