annulus, colored like the pileus below, sometimes slightly 
reticulated at the top; spores ferrugznous brown, .0004 to 
.0005 in. long, .00016 to .o002 broad. 
Pileus 2 to 4 in. broad; stem 3 to 5 in. long, 4 to 6 lines 
thick. 
Thin woods of tamarack, spruce and balsam. New York, 
Peck. 
This species is so closely related to the European JB. 
larictnus that it might easily be considered an American 
form of that species or at most a variety of it. I have not 
seen its pileus squamose nor its stem scrobiculate and there- 
fore for the present keep it distinct. “The spores are a 
much paler brown than those of Agarzcus campestris, and 
incline toward ferruginous. The Friesian arrangement 
would require this species to be placed among the Favosi, 
but its affinities appear to me to be with the Viscipelles. 
Its locality is thus far limited to the Adirondack region of 
this State.

Pileus flat or convex, viscid, sordid brown, streaked with 
the remnants of the veil, especially near the margin which 
is white, very thin, and when partly grown singularly pen- 
dent, flesh white, changing to bluzsh; tubes large, angular, 
unequal, slightly decurrent, at first sordid white or gray, 
sometimes tinged with green near the stem, afterward

adheres partly to it and partly to the margin of the pileus, 
white but stained by the brownish spores and tinged with 
yellow at maturity ; spores .o004 in. long, .o0025 broad. 
Shaded grassy ground. New England, /vosz. 
Probably this is only a variety of the preceding species,
