39 Marasmius olneyi Berk. & Curt. 



Ann. Mag. Nat. Hist. Ill 4:295. 1859. 



Pileus membranous, convex, then plane or depressed, 8-10 mm 

 broad; surface glabrous, dull-rufescent, margin striate at first, 

 then radiately rugose; lamellae joined to a collar which may become 

 free, subdistant, white, the edges slightly crenulate; spores 9-1 1 

 by 4-5 /a; stipe pulverulent-tomentose, white, 3.5-4 cm long. 



Upon dead twigs. Not reported from New York. It is not un- 

 likely that this species will be found within the State, since it has 

 been reported from both Rhode Island and Michigan. 



40 Marasmius ramealis (Bull.) Fries 

 Epicr. Myc. 381. 1838. 



Pileus subfleshy, plane or depressed, obtuse, 4-9 mm broad ; sur- 

 face rugulose, opaque, white, disk with a reddish tint, margin not 

 striate; lamellae adnate, connected behind, subdistant, narrow, 

 white; spores ovoid, apiculate, 8-10 by 3-3.5 /*; stipe short, stuffed, 

 white, reddish below, farinaceous, 12-18 mm long, i mm thick. 



Upon dead twigs and branches in woods. Not common. 



41 Marasmius concinnus Ellis & Ev. 

 Proc. Acad. Nat. Sci. 1893. 



Pileus minute, convex, cespitose, i mm broad; surface pruinose, 

 smoke-brown ; lamellae adnate, subdistant, pruinose, the edges ob- 

 tuse; spores globose, hyaline, 3 /jl; stipe attenuate above, white, 

 hairy strigose below, pruinose-pubescent at the apex, 2 mm long. 



Upon dead Euonymus twigs. Known only from New Jersey. 



Further observations are needed to determine whether this is a 

 good species or merely a small form ofM. ramealis (Bull.) 

 Fr. or other related species. 



42 Marasmius cucullatus Ellis 

 Torrey Club Bui. 6, p.76. 1876. 



Pileus thin, campanulate, 1-2 mm broad; surface sulcate-striate, 

 closing around the stipe when dry, pale straw color ; lamellae adnate, 

 about 12, of unequal length, paler than the pileus ; spores not found ; 

 stipe slender, pale straw color, with thin white tomcntum at the
