nulus 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 Jonesul. 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. soboliferus 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 I 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 I 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.
