" Lycoperdon ruhro-flavum sp. nov. Small, from less than an 

 inch to an inch and a half and nearly as broad, obconic, tapering 

 gradually downward to the rooting origin, rather than contracted 

 into a stem-like base. Peridium thin, vanishing irregularly above, 

 where it is orange-red to orange-brown in color, evenly rounded, 

 and farinaceous, with scattered, low, conical spines and granules, 

 which become blackish from greyish white; below brownish pink, 

 naked, shining, and irregularly shrunken-rugose. Capillitium and 

 spores olivaceous orange, the external portion having the orange 

 tint deeper and becoming bright orange-red when exposed by the 

 secession of the peridium. Spores subglobose, with a depression 

 on one side, mostly non-pedicellate, smooth, very small, about 

 .003 mm. in diameter."

A Meeting of Pathologists on Long Island 



About one hundred plant pathologists, representing many sec- 

 tions of America, as well as England and Holland, met on Long 

 Island, June 24-28, to study potato diseases in the field and to dis- 

 cuss these and other diseases of immediate interest to farmers 

 and horticulturists. The plans were carefully arranged by Dr. 

 M. F. Barrus ; the Farm Bureau prepared charts; and many 

 farmers loaned their cars for tours to various sections of the 

 Island. 



On Tuesday afternoon, the pathologists met in Riverhead and 

 were welcomed by Mr. Talmage ; on Wednesday, they made a 

 tour of the North Side, returning to Riverhead for an evening 

 meeting; on Thursday, the South Side was visited, and a meeting 

 was held at Watermill, with addresses by Dr. Cotton, of Eng- 

 land, Dr. Quanjer, of Holland, Dr. Pethybridge, of Ireland, and 

 Dr. Edson, of Washington ; on Friday, an inspection trip was 

 made in Nassau County, starting from Mineola; and on Friday 

 evening there was a conference at the McAlpin Hotel in New 

 York City. 



A meeting of Northeastern Pathologists, in charge of Prof. 

 C. R. Orton, was held at the Brooklyn Botanic Garden on Satur- 

 day, June 28, at which potato leaf-roll, the potato wart disease, 

 apple scab, etc., were discussed and an illustrated lecture given by 

 Dr. Quanjer. There was also a meeting of the advisory board.
