distinct areas or scales. Neither is the stem usually scaly but rather 
clothed with soft tomentose or almost silky fibrils) The lamellz are 
crowded and some of them are forked. At the furcations there are 
slight depressions which interrupt the general level of the edges and 
give them the appearance of having been eaten by insects. The plant 
has a slight odor, especially when cut or bruised. 
AGARICUS ACUTESQUAMOSUS, Wein. 
Acute-scaled Agaric. 
“ Pileus fleshy, obtuse, at first hairy-floccose, then bristly with erect 
acute squarrose scales ; stem somewhat stuffed, stout, bulbous, pruinose 
above the moderate-sized annulus ; lamelle approximate, lanceolate 
simple.” — Hymen. Hurop., p. 31. 
Pileus convex or nearly plane, obtuse or broadly subumbonate 
clothed witha soft tawny or brownish-tawny tomentum which usually 
breaks up into imperfect areas or squamz, rough with erect acute 
scales which are generally larger and more numerous on the disk ; 
lamelle close, free, white or yellowish ; stem equal, hollow or stuffed 
with webby filaments, subbulbous ; spores about .0003’ long, .00012’ 
—.00016' broad. 
Plant of the same size as the last.

Fries remarks that this species agrees so closely with the preceding 
one that he thinks the two should be united. The chief differences 
set forth in the descriptions already quoted consist in the appressed, 
tomentose scales and branched lamellz of the one and the erect acute 
scales and simple lamelle of the other. Now in the American plants 
I find erect acute scales on all the specimens, both those with branched 
and those with simple lamelle, so that the difference between the two 
forms is reduced with us to that of the lamelle alone. It is therefore 
probable that they will have to be united. The form found in the hot 
houses seems to have the tomentum of the pileus less dense and the 
_ erect scales more numerous than in the form growing in woods. The 
annulus is frequently lacerated. In the specimens of the woods the 
erect scales are sometimes blackish in color, and they then contrast 
quite conspicuously with the tawny or brownish-tawny tomentum be- 
neath them. They vary in size and shape. Some resemble pointed 
papille, others, being more elongated, are almost spine-like. These are 
sometimes curved. They are generally larger and more numerous on 
the disk than elsewhere, and often they are wholly wanting on the 
margin.
