ting the orbicular or elliptical erumpent subpulverulent disk ; asci 

 .0008 to .001 in. long; spores allantoic! .00024 to .0003 in. long. 



Bark of balsam fir, Abies balsamea. Labrador. Waghorne. 



This fungus is allied to but differs from Valsa Fricsii 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 1 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 H. 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.
