ment station. The entire work consists of 129 pages and is a 

 valuable guide to the fungous flora of the island, as well as a 

 basis for further study. — F. J. Seaver. 



Dr. S. M. Zeller, who has been special investigator in timber 

 pathology for the Southern Pine Association, of New Orleans, 

 Louisiana, with a laboratory at the Missouri Botanical Garden, 

 St. Louis, has been appointed investigator in fruit diseases at the 

 Oregon Agricultural College, Corvallis, Oregon. 



Bulletin 759 of the Bureau of Plant Industry, by Fred R. 

 Jones, deals with the leaf-spot diseases of alfalfa and red clover 

 caused by the fungi Pseudopeziza Medicaginis and Pseudopeziza 

 Trifolii respectively. From his investigations he concludes that 

 the two fungi are morphologically and physiologically distinct 

 although they have been regarded by some as being identical. Of 

 the several imperfect fungi which have been reported as the 

 conidial stage of this fungus, none have been found to be related 

 and no other spore form than the ascospore form apparently ex- 

 ists. Infection is produced by the direct penetration of the ger- 

 minating ascospores through the cuticle and epidermal wall. The 

 fungus overwinters on the dead leaves which .escape decay and 

 ascospores produced in the spring furnish the source of new in- 

 fection. — F. /. Seaver. 



In the report of the State Botanist of New York for 191 7, just 

 issued, Dr. H. D. House describes a new species of Flumaria 

 under the name of Hurnaria Peckii. The species occurs on de- 

 caying hay and is accompanied by a Sclerotium. In the same 

 report a number of new species belonging to various groups are 

 described by Dearness and House. The bulletin also contains an 

 article by G. F. Atkinson on Collyhia campanulata Peck and its 

 near relatives in the eastern United States, and one by Dr. L. O. 

 Overholts on the species of Poria described by Peck. The last 

 article is illustrated by twenty-three plates. — F. J. Seaver.
