Living leaves of Trillium. Illinois. Forbes. 



CELLULOSPORIUM (,cn. nor. 



Perithecia sph^eriform, fragile, rupturing irregularly or tlie whole 

 upper part falling away; spores large, multicellular. 



This is a Coniomycetous genus belonging to the Order Sph^ronk- 

 MEi. It is apparently related to the genus Coniothyrium but that is 

 characterized by its simple spores, so that our plant could not be re- 

 ferred to it without violating the generic character. I have therefore 

 been obliged to institute a genus for its reception. 



CELLULOSPORIUM sPH.i5R0SP0RUM.— Perithecia superficial, subglobose, 

 .01-02 of an inch in diameter, fragile, black ; spores subglobose or 

 broadly elliptical, colored, cellular, .0008-0012 of an inch long. 



Decaying Avood. Illinois. Forbes. 



The fungus appears to the naked eye like some minute black 

 Sphseria scattered over the surface of the wood. 



PucciNiA ATROPUNCTA P. &. C. u. .vyj.— Spots Very small, yellowish, 

 generally with a brownish center; sori numerous, small, slightly 

 prominent, black ; spores oblong-clavate, obtuse, constricted at the 

 septum,-. OOIG- 002 of an inch long, .0008-.0009 of an inch broad, the 

 pedicel generally shorter than the sjiore. 



Living leaves of Veratrurn Woodii. Allenton, Missouri. Commu- 

 nicated by 6r. W. Clinton. Jefferson County, Missouri. Communica- 

 ted by E. A. Ran. Collected by G. W. Letterman. 



This species is quite distinct from Paccinia Veratri, both in color of 

 the sori and in the character of the spores. 



Rhytisma sparsa p. & C.n. sp. — Stroma very small, thin, scattered, 

 less than one line in diameter, suborbicular, slightly convex, black, 

 rupturing by two or three short irregular chinks ; asci obovate or el- 

 liptical, eight-spored ; spores oblong, uniseptate, slightly colored, 

 .OOOS-.OOl of an inch long, slightly constricted at the septum, the 

 cells generally a little unequal. 



Both sides of living leaves of S((bal Pahnetfo. Fiorida. Clinton. 



This lihyti.sma is a very small one, appearing to the naked eye like 

 mere dots on the leaf. There is a small pallid or yellowish spot on 

 the leaf opposite each stroma. 



Some Notes from Northern Dakota and Montana. — In a paper 

 contributed to the Medical Record upon the "Climate and Diseases of 

 Northern Dakota and Montana," Dr. P. F. Harvey makes the follow- 

 ing mention of the botany of that region. His observations have
