ting the orbicular or elliptical erumpent subpulverulent disk; asci 
-0008 to .oo! in. long; spores allantoid .00024 to .0003 in. long. 
Bark of balsam fir, Adies dalsamea. Labrador. Waghorne. 
This fungus is allied to but differs from Valsa Friesii in its 
larger pustules, more numerous perithecia and shorter asci and 
spores. The color of the disk is grayish or grayish-green. 
HyGropHorus NiGRIDIus. Pileus fleshy, convex, obtuse or 
subumbonate, glabrous, grayish-brown or black-brown, often a 
little darker in the center, flesh white; lamellae distant, decurrent, 
white; stem rather slender, solid, brownish, white at the top; 
spores elliptical, .0004 to .0005 in. long, .00024 to .0003 broad. 
Pileus I to 2 in. broad; stem 1 to 2 in. long, 2 to 4 lines thick. 
Gregarious or rarely two or three united at the base. Pine and 
fir tree woods. Prince Edwards Island. October and November.

This fungus differs from A. caprinus Fr. in its smaller size, 
glabrous pileus and larger spores. A description of it was pub- 
lished in the Country Gentleman of November 29, 1894, but one 
is here given that it may be more readily accessible to mycologists. 
In many of the foregoing descriptions I have been obliged to 
give the colors indicated by the dried specimens. It is not likely 
therefore that they will in all cases agree rigidly with the colors of 
the fresh plant. 
| Hypericum boreale (Britton) and related Species. 
By EvucENE P. BICKNELL, 
At York Harbor, Maine, Hypericum Canadense L. abounds, 
Presenting itself in varying forms; Hypericum majus (Gray) Britton 
frequently grows with it, either strongly typical or with aberrant 
tendency; Hypericum mutilum L. is common also. 
More characteristic of the region, however, than any of these 
is a small species, which grows in abundance in open situations, 
about the muddy borders of pools or in moist sandy soil, and 
_ Shows some interesting lines of variation. Some fragmentary 
specimens, collected in 1888, were pronounced by Dr. Britton to
