C. Stipe short, without a root, insititious (i. e. attached at 
the base by a tubercle or by flocci). 
e. Stipe glabrous, shining. 
9. M. catorus, Pers.—Pileus a little fleshy, tough, convexo-plane or 
depressed, even, at length rugose. Stipe hollow, equal, glabrous, 
shining, reddish-brown. Lamelle emarginate-attached, thin, white. 
Growing on sticks, the roots of grasses, etc. Pileus 3-14 in. in di- 
ameter, the stipe 2-3 in. long. The younger pileus even, red-brown, 
soon changing to white. 
10. M. anomarus, Peck.—Pileus a little fleshy, tough, convex, even,’ 
reddish-gray. Stipe hollow, equal, glabrous, pallid above, red-brown 
below. Lamelle rotundate-free, close, narrow, whitish or pallid. 
Growing on sticks among leaves in woods. Pileus 1-2 in. broad, 
stipe 2-3 in. long. This is a very beautiful Marasmius; it grows quite 
large with us. 
f. Stipe velvety or pruinose. 
11. M. racineus, n. sp.—Pileus a little fleshy, convex then plane or 
depressed, at length somewhat repand, rugose-striate. Stipe short, 
hollow, pubescent, thickened upward; the base somewhat tuberculose. 
Lamelle short-adnate, somewnat crisped, close, pale-reddish. 
Growing thickly over the bark at the base of living beech trees. 
Pileus 3-14 in. broad, stipe 4-1 in, long. Pileus reddish-pallid or alu- 
taceous, the stipe of the same color, the lamelle a little paler. 
12. M. opacus, B. & C.—Whitish. Pileus a little fleshy, convex, 
rugulose, opaque, pulverulent. Stipe pulverulent, furfuraceous below. 
Lamelle attached, distant, ventricose. 
On leaves and twigs. Pileus 1-2 in. across, stipe 1-14 in. long. 
The pileus is convex or slightly depressed around a central umbo, and 
opaque not pellucid, it is dirty white and scarcely striate or sulcate ; 
the stipe is of the same color as the pileus. The species is nearly 
allied to M, ramealis, Bull., but the stipe is more elongated, and is 
not darker at the base. I am indebted to Mr. Wm. C. Stevenson, of 
the Philadelphia Academy of Sciences, for the original description.
