24 Marasmius resinosus (Peck) Sacc. 



Syll., 5 :522. 1887. 



Ann.. Rep't N. Y. State Mus., 24 :88. 1872 (As Marasmius decur- 

 rens Peck). 



N. Y. State Mus. Bui. 67, p.38. 1903 (As Marasmius resinosus 

 nivens Peck). 



N. Y. State Mus. Bui. 94, p.40. 1905 (As Marasmius resinosus 

 candidissimus Peck). 



Pileus thin, convex, subcespitose, 8-13 mm broad; surface 

 minutely tomentose, pure white, becoming yellowish when dry; 

 lamellae arcuate-decurrent, interspaces rugose-reticulate, subdis- 

 tant, narrow, tapering toward each end, white, the edges discolored ; 

 spores 6-"] by 4 ju ; stipe slender, firm, equal, white, surface minutely 

 tomentose, 2.5-5 cm long, i mm thick. The stipe and lamellae are 

 usually dotted with minute, resinous, granular particles. 



Upon vegetable debris upon ground. Common. 



The pure white color of the pileus is frequently obscured by the 

 substratum within or upon which the plant grows, which sometimes 

 gives it a grayish or brownish appearance. 



25 Marasmius salignus Peck 



Ann. Rep't N. Y. State Mus., 35:135- 1884. 



Pileus submembranous, convex or plane, sometimes subumbili- 

 cate, 4-10 mm broad ; surface dry, glabrous or subpruinose, white, 

 margin even; lamellae often joined at the base, rarely forking, 

 adnate, subdistant, narrow, white; spores ovoid or subellipsoid, 

 6-7 by 4 ; stipe slender, stufifed, reddish brown, slightly furfur- 

 aceous or pruinose, 1.5-2.5 cm long, i mm thick. 



Upon the bark of trees. Not common. This species seems to be 

 very closely related to M. candidus (Bolt.) Fr. Some of 

 Peck's collections might well pass for the plant figured by Bolton 

 (Hist. Fung. pi. 39, fig. D.) 



26 Marasmius nigripes (Schw.) Fries 

 Epicr. Myc. 383. 1838. 



Pileus membranous, 6-12 mm broad, campanulate, umbonate; 

 surface white, pruinose, pellucid, margin striate; lamellae adnate, 

 broad, white or pallid, becoming dark in dried plants ; spores 

 angular, 8-9 ju; stipe insititious, slightly tapering downward, horny, 

 blackish, white-pruinose, becoming brown in dried plants, 3.5-4 

 cm long, 1-2 mm thick.
