riulus and volva at the base of the stem. Only mature specimens 

 "were seen, consequently the characters of the young plant remain 

 unknown and the description to that extent is defective. 



Coprinus Jonesii. Pileus submembranous, campanulate be- 

 coming broadly convex or expanded and split or revolute on the 

 margin, very blunt or truncate at the apex when young, everywhere 

 covered with tawny-gray or pale-cervine floccose scales which 

 wholly or partly disappear with age revealing the striate surface 

 beneath ; lamellae crowded, linear, free, at first white or whitish, 

 becoming black ; stem equal or slightly tapering upward, minutely 

 floccose, hollow, white; spores black, broadly elliptical, .0003 to 

 .00035 in. long, .00025 broad, with an apiculus at one end. 



Pileus 1 to 2 in. broad ; stem 2 to 3 in. long, 2 to 3 lines thick. 



Plant fragile, sometimes caespitose. In a cellar. Vermont. 

 April. Prof. L. R. Jones. 



The species is closely related to C.fimetarius, of which it might 

 easily be considered a variety, but it is easily distinguished by the 

 truncate apex of the young pileus, the differently colored scales and 

 the smaller spores. C. sobolifems Fr. has the pileus truncated at 

 the apex, but it is a very different species. 



Coprinus apiculatus. Pileus membranous, campanulate or 

 deeply convex, acute 01 apiculate, furfuraceous, plicate-striate to 

 the disk, grayish; lamellae few, subdistant, reaching the stem, 

 black ; stem filiform, glabrous, white ; spores elliptical, black, .0003 

 in. long, .00016 broad. 



Pileus about 3 lines broad; stem 1 to 1.5 in. long, scarcely 

 half a line thick. Lewiston, Pennsylvania. Mrs. E. B. Noyes. 



Boletinus borealis. Pileus fleshy, convex, obtuse or subum- 

 bonate, brownish yellow, obscurely and somewhat reticulately 

 streaked with reddish-brown lines ; pores large, angular, unequal, 

 slightly decurrent, brownish-yellow; stem short, equal or slightly 

 tapering upward, brownish-yellow with a whitish mycelioid to- 

 mentum at the base ; spores oblong, .0004 to .0005 in. long .00016 

 to .0002 broad. 



Pileus 1 to 2 in. broad; stem about 1 in. long. 



Sandy soil. Capstan Island, Labrador. October. Waghorne. 



The markings of the pileus appear as if due to the drying of 

 a glutinous substance. The radiating lamellae and the transverse 

 partitions of the interspaces are very plainly shown. Described 

 from two dried specimens.
