Mycologia 



genus Rhisina shows no evidence of an enclosing veil at any stage 

 in its development, a fact which has been demonstrated by Fitz- 

 patrick. The sexual apparatus is to be described in a later paper. 



A specimen of Schizophyllus alneus (L.) Schroet, usually 

 known as S. commune, was found on September 3, 191 7, by Dr. G. 

 Clyde Fisher, at Douglaston, Long Island, growing on a rotten 

 apple. Several sporophores had emerged from the substratum at 

 three or four points and had just about reached maturity when I 

 saw the specimen. This would seem to indicate that spore germi- 

 nation and development of fruit-bodies may proceed quite rapidly 

 in this species. 



" The Cultivation and Diseases of the Sweet Pea " is the title 

 of a book recently published by J. J. Taubenhaus, of the Texas 

 Experiment Station, with an introduction by Mel Cook, of 

 Rutgers College, New Jersey. The book is based largely on the 

 practical experience of the writer and is written in a popular 

 manner so as to appeal to the practical grower. About half of 

 the book is devoted to the culture of the sweet pea and the re- 

 mainder to the diseases which threaten to discourage the cultiva- 

 tion of this ornamental plant. The various insect and fungous 

 pests are considered in detail with suggestions for their control. 

 The book consists of xx + 2 3 2 pages with 46 figures and is 

 printed in large type so as to be easily legible. 



A disease of the hemlock tree due to Fomitiporia tsugina 

 Murrill was discovered by Mr. Percy Wilson at East Hebron, 

 New Hampshire, in August, 1905. In July, 1917, Mr. Wilson 

 revisited the type locality and gathered specimens from the trunk 

 of the same tree, which was found to be dead and prostrate on 

 the ground. These latter specimens were over an inch thick and 

 broadly effused over the trunk. Living hemlocks recently ex- 

 amined by Mr. Wilson near Bristol, New Hampshire, were also 

 found to be attacked by this fungus, which is known to occur in 

 New Hampshire and New York, always confined to the hemlock. 

 The disease is probably important and should be further investi- 

 gated both by foresters and mycologists.
