Mycologia 



Agricultural Station in 1918, prepared by E. D. Colon and F. S. 

 Earle, states that the disease is incurable so far as individual 

 plants are concerned and is probably hereditary. The employ- 

 ment of strictly sound material for propagation, inspection of 

 growing crops at frequent intervals, and eradication of all but 

 unquestionably sound canes are recommended as control 

 measures. 



Bulletin 829 of the U. S. Dept. of Agriculture, by E. W. 

 Brandes, contains an up-to-date and full discussion of this dis- 

 ease, with special reference to its occurrence in the United States. 

 Two colored plates accompany the bulletin. Methods of control 

 which originated in Java and Hawaii and have been used with 

 success in Porto Rico are described in detail. 



A Revision of the British Clavariae, by A. D. Cotton and E, 

 M. Wakefield, appeared in the Transactions of the British Myco- 

 logical Society for September, 1919. This work of revision was 

 begun in 1905, when it was intended to include all the described 

 species of Clavaria, numbering about 400, and to publish a mono- 

 graph of the entire genus. The confusion regarding European 

 species, however, and the necessity for considerable careful micro- 

 scopic work, caused the authors to devote their attention at first 

 to the British species, numbering 37 in all, including C. Broomei 

 and C. Invalii, described as new, and C. gig asp or a; C. Crosslandii, 

 C. straminea, and C. persimilis, recently published elsewhere. 

 Clavaria fastigiata is reduced to a variety and 22 names have 

 been excluded from the British list as synonyms or indetermin- 

 able. The paper contains excellent descriptions and many inter- 

 esting notes but no plates, although many references to illustra- 

 tions are included. 



Bulletin 214 of the Connecticut Agricultural Experiment Sta- 

 tion comprises the report of the botanist, Dr. G. P. Clinton, for 

 the years 191 7 and 191 8. Five pages are devoted to the "In- 

 spection of Phaenogamic Herbaria for Rusts on Ribes sps.," by 

 Clinton, and 32 pages and 8 plates to " Infection Experiments of 

 Pinus Strobus with Cronartium ribicola/' by Clinton and Mc-
