REMARKS AND OBSERVATIONS 

 Aecidium hydnoideum B. & C. 



This parasitic leaf fungus attacks living leaves of the leather- 

 wood, Dirca palustris L. It usually forms a single large 

 yellowish or reddish yellow spot on a leaf. A single cluster of cups 

 commonly occupies each spot. 



Agrostis borealis Hartm. 



Along Mclntyre brook, Adirondack mountains. July. This is 

 an unusual form having the awn of the spikelet short and not ex- 

 serted. 



Boletus scaber Fr. 



In this species the hymenium or mass of tubes is usually more 

 or less depressed around the stem. In three specimens collected 

 in Rosedale, Long Island, by F. H. Ames the tubes are adnate at 

 first and then in drying separate from the stem carrying with them 

 a thin layer of the external coating, thereby forming a cuplike 

 depression about its insertion.

Cladonia cristatella vestita Tuck. 

 Sandy soil. Orient Point. November. R. Latham. 



Clavaria obtusissima minor n. var. 



Plant smaller than the type, with more numerous and more 

 slender branches and branchlets, the ultimate ones not so distinctly 

 consolidated nor umbilicate, but obtuse or obtusely dentate. 



Bolton, Warren co. September. For the description of the 

 species see chapter on " New species of extralimital fungi." 



Minor, rami ramulique numerosiores et graciliores, ultimati non 

 distincte consolidati ne umbilicati, sed obtusi vel obtuse dentati. 



Cynanchum nigrum (L.) Pers. 

 The black swallowwort is abundant near Rochester not far from 

 Cobbs Hill reservoir. It usually grows in small patches of six to 

 ten feet in diameter. The pods often divaricate in such a way 

 as to give a somewhat stellate appearance to their arrangement.
