somewhat deformed, concolorous. Lamelle arcuate and long-decurrent 
in some specimens, in others nearly plane and adnate-decurrent, at 
first grayish, at length bright flesh-color. Spores angular. 
The imperfect and abortive forms present all stages of imperfection 
to a complete obliteration of all semblance of stipe and pileus when the 
fungus consists of a rounded more or less lobed mass. 
In woods about old logs and stumps. Pileus 3 in. or more in breadth, 
stipe 2-3 in. long. The abortive forms sometimes cohere together in 
large masses. ‘There is an odor of fresh meal, and a not unpleasant 
taste. 
Susgenus XIV.—Leprtonia, Fr. 
Spores rosy. Pileus thin, umbilicate, or with the disk darker ; the 
margin at first incurved. Stipe cartilaginous, tubular, polished, 
shining. Lamellee at first attached or adnate, but easily seceding. 
90. A. ASPRELLUS, Fr.—Pileus somewhat membranaceous, convex 
then explanate, sometimes glabrous, sometimes fibrillose, striate, the 
umbilicus villous and at length scaly, fuliginous, then livid gray. Stipe 
hollow, slender, even, glabrous. Lamellz adnate, seceding, equally at- 
tenuate from the stipe to the margin, whitish-gray. 
In pastures and grassy places. Pileus 1-14 in. broad. Stipe 1-2 in. 
long. Stipe typically livid, but varies in color from brown to green and 
biue. Pileus at first dingy or mouse-color, soon plane and livid-gray. 
Note.—Our Hyporhodii have not yet been looked for with sufficient 
care; three or four of the subgenera are yet wanting, which must have 
some representatives. I have had specimens of four or five other 
species, but so, few in number, or so imperfect, that I am not yet able 
to assign them to any place. Agaricus sapidus, a common Pleurotus, 
with lilac-tinted spores, and Panus dorsalis, with red spores, are eau to 
be looked for in this series.
