192 FUNGUS-FLORA. 



expanded, umbonate, becoming every where broken up into 

 small floccose, squarrose scales, or torn into smaller adpressed 

 scales, dry, rufous ; margin at first involute and tomentose 

 from tbe veil ; gills very slightly sinuate, almost adnate, 

 rather distant, 3-6 lines broad, whitish at first, then spotted 

 with red, at length rufescent ; stem about 3 in. long, 4-8 

 lines thick, hollow, equal, round, remarkably fibrillose, 

 more or less evidently cortinated, apex naked, whitish with a 

 rufescent tinge; spores subglobose, 6-7 [x diameter. 



Agaricus (^Triclioloma) vaccinns. Fries, Epicr., p. 33 ; Cke., 

 Hdbk., p. 30; Cke., Illustr., pi. 60 (called Ag. imbricatus). 



In pine, &c. 



Allied to T. imhricatum, but differs in the stem being hollow, 

 and its apex naked (i.e. not powdery), and in the flesh 

 becoming reddish. 



Tricholoma imbricatum. Tr. 



Pileus 3-5 in. across, flesh thick, white; convex then 

 expanded, obtuse, quite dry, rufous-umber, becoming broken 

 up into minute innate squamules ; margin at first incurved 

 and downy ; gills sinuate and adnexed, 2-3 lines broad, 

 rather crowded, white then rufescent ; stem 3-5 in. long, 

 J-| in. thick, paler than the pileus, apex with white pulve- 

 rulent down, solid ; spores 6 X 4 /><.. 



Agaricus imhricatum, Fries, Obs., i. p. 27; Cke., Illustr., 

 13l. 199; Cke., Hdbk., p. 30. 



In pine and other woods. 



Stem solid, firm (often riddled by larvae), sometimes short, 

 conical, 1-2—2 in. long and up to 1 in. thick, sometimes drawn 

 out, 3 in. long, almost equal, adpressedly fibrillose, apex 

 white, pulverulent with white squamules. Pileus fleshy, 

 compact, broadly convex then expanded, obtuse, very dry, 

 umber or rufous-umber, very opaque, 3 in. and more broad, 

 disc remaining smooth, the remainder broken up into- 

 squamules, fibrillose towards the margin. Margin thin, 

 slightly incurved at first, downy, then almost naked. Gills 

 slightly emarginate, almost adnate, rather crowded, 3 lines 

 broad, entirely white when young, then rufous. (Fries.) 



T. vaccinum somewhat resembles the present species, but 

 differs in the distinctly corticate, hollow stem having the 

 apex naked ; umbonate pileus, &c.
