connexa and presented it to the Garden herbarium. This species 

 was first collected in the New York Botanical Garden and had 

 been known only from the original collection. 



Grifola Sumstinei Murrill was collected three times last au- 

 tumn in the vicinity of New York City. A splendid museum 

 specimen was first sent in from Ridgewood, New Jersey, by Mrs. 

 Alexander Taylor ; and it was afterwards found at Princess Bay, 

 Staten Island, by Mr. F. F. Wilmousky, and at Scarsdale by Mrs. 

 L. M. Keeler. This large tree-destroying polypore is interme- 

 diate between Grifola Berkeleyi and Grifola frondosa, and would 

 probably be confused by some with the latter species, but its lobes 

 are broader and soon become blackish, both above and below. 



Psilocybe polycephala (Paulet) Peck was collected by W. A. 

 Murrill in his yard near Bronx Park on September 27, 1918. It 

 had appeared in the same spot three consecutive seasons, growing 

 in the grass among Clitocyhe miilticeps. The clusters are very 

 dense and the small caps are yellowish-brown and very hygropha- 

 nous, becoming pallid on drying. According to Peck, the species 

 is edible ; its taste is certainly very agreeable. The gills are so 

 slow in changing color that it might easily be mistaken at first for 

 a white-spored species. 



An article of unusual interest by Shantz and Piemeisel on 

 fungous fairy rings in eastern Colorado and their effect on vege- 

 tation appeared in Vol. XI of the Journal of Agricultural Re- 

 search, the 56 pages of text being illustrated by 21 plates and 15 

 figures. The paper begins with a summary of past studies and 

 a list of the fungi that have been reported to form rings. Some 

 are said to be destructive to grass and other forms of vegetation 

 and others are claimed to be beneficial by causing stimulation of 

 growth. The annual enlargement, as well as the age, of the rings 

 is discussed, and some of the very large rings are estimated to be 

 from 400 to 600 years old !
