Journal Royal Horticultural Society, Vol. XXX, 1906. 



In this volume there were published two mycological articles 

 by Ernest vS. Salmon, namely, "On the American Mildew and the 

 need for Legislation ;" and "Pn a Fungus Disease of the Cherry 

 Laurel," (Prunus laurocerasus L.). 



Journal Royal Agricultural Society, Vol. 67, 1906. 



In the "'Annual Report for 1906 of the Consulting Botanist,'*^ 

 William Carruthers, a short popular account is given of a few 

 diseases of plants, as Pear rust (Gymnosporangium sabinae 

 Dicks), and the American Gooseberry Mildew ( Sphaerotheca 

 mors-uvae Berk.).

In the "Report of the State Botanist 1906," which is Bull- 

 etin 116, Botany 10, New York State Museum, published July 

 1907, we find the usual plan of these valuable annual accounts. 

 About two dozen species of Mushrooms are described and sev- 

 eral new names are given. Eleven species of edible Fungi are 

 described and illustrated by colored plates. A monograph is 

 given of the New York species of Hygrophorus, and of Russula. 

 These are accompanied with full clear keys, making them very 

 useful to those who wish to study our Agarics. It would require 

 small addition to extend the range and include all species in the 

 Eastern United States; we hope to see these studies of Agaric- 

 aeace from year to year until all the genera are presented. 



Sheldon, John L. 



In an article in Science, August 9, 1907, this author states 

 that he has been, during the past four years, collecting specimens 

 of Apple leaves and fruits having spots on them caused by fungi. 

 The fungus here discussed is Phyllosticta solitaria E. & E., found 

 on leaves also of the crab-apple. Then it was found on the 

 petioles of the common and the crab-apple, also on yearling and 

 older branches. This disease has been called "fruit-blotch," 

 "apple-blotch," "dry-rot," etc. 



Heald, F. D. 



In Science, for August 16, 1907, some observations on "Gym- 

 nosporangium macropus," as to the time of infection, were made 

 in Nebraska, 1906 and 1907; concluding that two explanations 

 suggest themselves: "(i) The fungus is either perennial in 

 the cedar, or, (2) The aecidiospores of one season produce the 

 cedar apples w.hich appear in June of the next year and reach 

 maturity in the autumn." Though there is some evidence of the 

 perennial character of the fungus, the observer thinks his second 

 explanation the more probable.
