distinct areas or scales. Neither is the stem usually scaly but rather 

 clothed with soft tomentose or almost silky fibrils. The lamellae 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.

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 ; lamellae approximate, lanceolate 

 simple." — Hymen. Uurop., p. 31. 



Pileus convex or nearly plane, obtuse or broadly subumbonate 

 clothed with a soft tawny or brownish-tawny tomentum which usually 

 breaks up into imperfect areas or squamae, rough with erect acute 

 scales which are generally larger and more numerous on the disk ; 

 lamellae 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 lamellae of the one and the erect acute 

 scales and simple lamellae 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 lamellae, so that the difference between the two 

 forms is reduced with us to that of the lamellae alone. It is therefore 

 probable that they will have to be united. The formiound in the hot 

 nouses 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 

 papillae, 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.
