The Mycologic Flora of the Miami Valley, O. 65 
_Suscenus I[V.—TricHoLoma, Fr. 
Spores white (except in No. 27). Stipe fleshy, not corticate. Hy- 
menophore confluent with the stipe, the lamelle sinuate behind. 
All terrestrial. 
a. Pileus white or whitish, 24, 25. 
6. Pileus gray or violaceous, 26, 27. 
c. Pileus brown or blackish, 28, 29. 
a. Pileus white or whitish. 
24, A. spERMATICUS, Paul.—White. Pileus somewhat fleshy, convex, 
then explanate, obtuse, repand, glabrous, viscid. Stipe stuffed, then 
hollow, elongated, twisted, even. Lamellz emarginate, rather distant, 
eroded. Spores .0056 mm. long. 
In woods in autumn. Pileus about 3 in. in diameter, the stipe 3-4 
in. long. The viscid pileus, shining when dry, and the twisted stipe 
often tapering at the base, distinguish the species. I find it rather 
scarce. 
25. A. LATERARIUS, Peck.—Pileus convex or expanded, pruinose, 
whitish; the disk often tinged with red or brown; the thin margin 
marked with slight, subdistant, short, radiating ridges. Stipe nearly 
equal, solid, white. Lamellz narrow, crowded, white, prolonged in little 
decurrent lines on the stem. Spores oval, .0046 mm. long, 
Around old rotten logs in woods. Pileus 2-4 in. broad, stipe 3-4 in. 
high. The pinched up margin of the pileus is a convenient mark of 
specific distinction. | 
b. Pileus gray or violaceous. 
26. A. TERREUS, Scheeff.—Pileus fleshy, thin, soft, campanulate, then 
expanded, umbonate, clothed with innate floccose or scaly down, mouse- 
eolor. Stipe stuffed, nearly equal, appressed-fibrillose, whitish. 
Lamellze attached, decurrent by a tooth, crenulate, white-gray. Spores 
somewhat elliptic, .0070.0055 mm. 
In woods, solitary. Pileus 2-3 in. broad, stipe about 3 in. high. 
Very scarce. The spores in my specimen are rather larger than in the 
British plant where they are given as nearly spherical and .0050 mm. 
long; yet the agreement is close otherwise. 
27. A. pERsoNnATUS, Fr.—Pileus compact, then soft, convexo-plane’ 
obtuse, regular, glabrous, moist. Stipe solid, obese, somewhat bulbous, 
villous. Lamellze rotundate-free, close, violaceous then sordid. Spores 
pale salmon color, regular, .006.003 mm.
