C. Stipe sfiort. without a i-oot, insititious (i. e. attached at 

 the base l\v a tubercle or by flocci). 

 e. Stipe glabrous, shining. 



9. M. CALOPUS, Pers. — Pileus a little fleshy, tough, convexo-plane or 

 depressed, ovoii, at longth ingose. Stipe hollow, equal, glabrous, 

 shiniii"-, reddish-browu. LamclljB emarginate-attached. thin, white. 



Growing on sticks, the roots of grasses, etc. Pileus |-1,V in- in di- 

 ameter, the stipe 2-3 in. long. The younger pileus even, red-brown, 

 soon changing to white. 



10. M. ANOMALUS, Peck.— Pileus a little fleshy, tough, convex, even, 

 reddish-gray. Stipe hollow, equal, glabrous, pallid above, red-brown 

 below. Lamellae rotun date-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 Marasraius; it grows quite 

 large with us. 



/. Stijje velvety or pruinose. 



11. ^I. FAGiNEUS, n. sp. — Pileus a little flesh^', convex then plane or 

 depressed, at length somewhat re|)an(l, riigose-striate. Stipe short,

 The pileus is convex or slightly depressed around a central umbo, and
