A scientific expedition to Colombia is being organized at Neu- 

 chatel, the leader being Dr, O. Fuhrman, professor of zoology at 

 Neuchatel University. Dr. Mayor will accompany the expedition 

 and devote his attention mainly to the parasitic flora. 



Several specimens of Pluteus cervinus were found April 9, 

 growing in a sawdust pile not far from Bronx Park, New York 

 City. The only other fleshy fungi noticed were Coprinus mica- 

 ceus, which is usually the first to appear in quantity in the spring, 

 and the common winter species, Collybia velutipes. All of these 

 species are described and figured in the first volume of this 

 journal. 



Owing to the excellent series of specimens of Pyropolyporus 

 praerimosus Murrill recently collected by Dr. George G. Hedg- 

 cock and his assistants on various species of oak and walnut in 

 Texas, Arizona, and New Mexico, it is now possible to connect 

 this species with Pyropolyporus Everhartii (Ellis & Gall.) Murrill 

 as a variety of the latter; the very rimose character being prob- 

 ably due to desiccation, as is the case with western forms of P. 

 igniarius, particularly the one found commonly on aspen. It 

 often happens that more complete collections will connect species 

 that at first appear both morphologically and geographically 

 distinct. 



"Resolved, That the American Phytopathological Society views 

 with alarm the recent introduction into America of two dangerous 

 European plant diseases: The potato wart, caused by Chryso- 

 phlyotis e'Jidobiotica Schilb., and the blister rust of white pine, 

 caused by Peridermium strobi Klebahn. The former has been 

 discovered in Newfoundland. The latter has been widely dis- 

 tributed in nine of the United States and in the Province of 

 Ontario, but is now believed to have been eradicated. 



''Resolved, that the society deplores the fact that, in the 

 absence of any national regulation in either the United States or 

 Canada, both governments are powerless to prevent the continued 

 introduction of these and other dangerous diseases, or their trans- 

 ference from one country to the other.
