sideration as a mere variety of the white washed mushroom and 

 not as a distinct species. I would not class it as an edible mush- 

 room but rather as a medicinal one. Its physiologic effects ap- 

 parently separate it more decidedly than any of its external 

 characters. 



Clitocybe morbifera Pk., collected by F. J. Braendle 

 near Washington, D. C, is a closely related species. Its name 

 was suggested by the fact that those eating it had been made sick. 

 In the dried state it is scarcely distinguishable from our sudorific 

 mushroom in external appearance, but its stem is hollow. When 

 fresh its pileus is tinged with grayish brown, but it becomes paler 

 in drying. This has also been collected near Minneapolis, Minn., 

 whence it was sent by Mrs M. E. Whetstone with an account of 

 a case of short illness caused by it in one who ate freely of it 

 for breakfast. Dr O. E. Fisher has sent specimens of it from 

 Detroit, Mich., with an account of the sickness it produces and 

 the accompanying symptoms. From these cases it appears that 

 the ill effects of the sickening mushroom are much more serious 

 and uncomfortable than those of the sudorific mushroom. 



Cornus canadensis elongata n. f. 



Stem elongated, bearing a pair of opposite leaves at each of 

 three or four nearly equidistant nodes, or bearing a whorl of four 

 leaves near the base and two or three pairs of opposite leaves 

 above, instead of the usual peduncle and flower cluster. Cran- 

 berry marsh, Sand Lake, Rensselaer co. and Averyville marsh. 

 North Elba. July and September. Sterile. 



This peculiar form has the appearance of Cornus suecica 

 L., the northern dwarf cornel, but its leaves have the venation of 

 the common dwarf cornel No flowering or fruiting specimens 

 were seen. 



Crataegus grayana Eggleston 



This rare thorn bush occurs in a single clump on Crown Point 

 west of the ruins of Fort Frederick. At Rossie it is represented 

 by several clumps near the Laidlaw house and a single outlying 

 clump about two miles south of the village. 



Cronartium ribicola F. de W. 

 Leaves of red currant, Ribes vulgare Lam. West Fort 

 Ann. October, 1909. S. H. Burnham. This is an interesting 

 discovery of a new locality for this fungus of which the uredo
