The Ohio Naturalist. 
[Vol. XIII, No. 5, 
40 mm. diameter, surrounded by a mycelium 15 mm. wide. In 
another specimen of about the same size the central part of the 
algal layer was covered again by a mycelium 12 mm. in diameter, 
so that now this mycelium was surrounded by an algal and a 
fungal layer in the shape of concentric rings. The apothecia in 
the last mentioned case were distributed as well on the inner as on 
the outer mycelium. 
The apothecia are usually provided with a great number of 
asci, each containing S colorless, more or less elliptical spores, 
which are liable because of their small size (11-10x7-8 mic.) to be 
blown to long distances by the wind. 
On finding a proper substratum, as seems to have been the case 
here, the algae on the moist sandstone, they reproduce innumerable 
new plants. They lead a symbiotic life, apparently without 
either benefit or harm to the algal symbiont, but certainly with 
benefit to the fungal part. 
MEETING OF THE BIOLOGICAL CLUB. 
Orton Hall, November 4, 1912. 
The club was called to order by Pres. W. M. Barrows. The 
minutes of the last meeting were read and approved. 
The principal business of the evening was the election of 
officers. The nominating committee reported the names of two 
candidates for each office and the following were elected: 
President, W. G. Stover 
Vice-President, Blanche McAvov. 
Secretary-Treasurer, Marie F. McLellan. 
Following the election came the president’s address on “Some 
Recent Work Along the Line of Mendel’s Law.” 
Prof. Barrows discussed Mendel’s original idea and showed 
that the results of modern work have been slightly different from 
Mendel’s expectations. The purity of germ cells and their un¬ 
changeability have been questioned. It has also been shown that 
units are not physiologically separate, but react on one another. 
He then took up the phenomena of sex-limited inheritance and 
showed illustrations from the experiments of Pearl and Surface on 
barred and non-barred chickens. 
He showed also that dominance is not a necessary factor in the 
production of Mendelian ratios. 
The meeting was then adjourned. 
Marie F. McLellan, Secretary.
