as if the stem were merely an elongation of the vertex. The 

 nearest ally is perhaps C crispus. 



27. Marasmius dichrous, n. s. Pileo subtiliter tomentoso siib- 

 velutino fusco ; stipite furfuraceo basi subdilatato ; lamellis li- 

 beratis. Curt. no. 2834. On rotten wood in dry swamps, South 

 Carolina. 



Pileus 1 inch or more across, convex, dark brown, clothed with 

 close matted down, sometimes appearing velvety. Stem 1-1 1 inch 

 high, scarcely a line thick, brown, clothed with furfuraceous 

 down ; base slightly dilated, villous. Gills at first adnate, sepa- 

 rating from the stem, and sometimes leaving a naked area 

 round it, moderately distant, ventricose ; interstices nearly even. 

 Spores white. 



Nearly allied to M. ramealis. It is however a larger species, 

 and remarkable for its dark brown pileus. 



28. Marasmius pusio, n. s. Pusillus; pileo membranaceo 

 fusco-purpureo striatulo; stipite gracili subtiliter tomentoso 

 opaco; lamellis adnatis crebris ventricosis albidis. Curt. no. 

 2043. On the bark of trees, summer and early autumn. South 

 Carolina, H. W. Ravenel, Esq. 



Pileus scarcely more than a line broad, membranaceous, re- 

 gular, slightly convex, pale purple-brown, delicately striate, 

 opake, very minutely pulverulent. Stem 8-10 lines high, very 

 slender, whitish, obscurely tomentose or pulverulent. Gills 

 moderately broad, numerous, ventricose, adnate, dirty white. 



A minute species, resembling somewhat Marasmius graminum, 

 but not very closely allied. The surface of the pileus resembles 

 that of such species as M.ferrugineus, the stem however is more 

 like that of M. opacus or M. spongiosus. 



29. Marasmius brevipes, Berk. & Rav. MSS. Pileo convexo 

 estriato atro-sanguineo ; stipite brevi filiformi aterrimo nitido e 

 mycelio repente similari enato; lamellis paucis adnatis rufis. 

 Rav. no. 1527. On dead twigs of oak, June, Santee Canal, South 

 Carolina, H. W. Ravenel, Esq. 



Pileus 1-2 lines broad, convex, dark blood-red ; margin even ; 

 stem filiform, jet-black, quite smooth, 1-2 lines high, springing 

 from creeping mycelioid threads of the same nature with itself; 

 gills ventricose, few, adnate, rufous. 



Allied to M. fmmatocephalus, &c., but distinguished at once 

 bv its short polished stem and dai*k gills. The colour of the 

 pileus is nearly that of M. atroruhens. 



30. Lentinus parvulus, n. s. Csespitosus; pileo submembra- 

 naceo infundibuliformi glabro, margine revoluto ; stipite gracili 

 lanuginoso ; lamellis angustis dichotomis decurrentibus albis. 

 Curt. no. 3624. On decayed wood, Pennsylvania, Dr. Michener. 



Csespitose. Pileus |-1 inch across, membranaceous, irregular.
