192 FUNGUS-FLORA. 



expanded, umbonate, becoming everywhere broken up into 

 small floccose, squarrose scales, or torn into smaller adpressed 

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

 from the 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 p, diameter. 



Agaricus (Tricholoma) vaccinus, Fries, Epicr., p. 33 ; Cke., 

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



In pine, &c. 



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

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

 becoming reddish. 



Tricholoma imbricatum. Fr. ' 



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, 

 i-f in. thick, paler than the pileus, apex with white pulve- 

 rulent down, solid ; spores 6 x 4 p.. 



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

 pi. 199; Cke., Hdbk., p. 30. 



In pine and other woods. 



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

 conical, 1^-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.
