Upon leaves, twigs etc., in woods. Rare in New York but com- 

 mon in Ohio and Michigan. Marasmius nigripes is 

 readily distinguished from all other species of Marasmius by its 

 irregularly angular spores. 



27 Marasmius papillatus Peck 



Ann. Rep't N. Y. State Mus., 24 76. 1872. 



Pileus submembranous, convex to expanded, papillate, gregarious, 

 1-2 cm broad ; surface obscurely striate, sordid white or gray, some- 

 times with a pink tint ; margin fluted in dry plants ; lamellae adnate 

 with slightly decurrent tooth, some decidedly decurrent, crowded, 

 narrow, white or yellowish: spores 8-9 by 3.5 /*; stipe slender, 

 deeply radicating, firm, hollow, concolorous, white-pruinose, 2.5-5 

 cm long, 1-2 mm thick. 



Upon mossy logs in woods. Common in the Adirondack moun- 

 tains. 



28 Marasmius perforans (Hoffm.) Fries 



Epicr. Myc. 385. 1838. 



Pileus submembranous, plane, not umbilicate, 8-12 mm broad; 

 surface rugulose, glabrous, pallid white, margin not striate ; con- 

 text with a stinking odor, not of onions ; lamellae adnate, many 

 dimidiate, simple, crowded, whitish; spores 6-8 by 2-4 /x; stipe 

 equal, hollow, brownish black, velvety, 2-3 cm long. 



Upon dead leaves of fir ; occasionally upon leaves of other kinds. 

 Common. 



This plant has been distributed as Marasmius a b i e t i s 

 (Batsch.) Fr. The plant which Batsch figures and describes as M . 

 agaricus abietus seems to be another species, possibly M . 

 a Hiatus (Schaeff.) Schrot. 



29 Marasmius squamula (Batsch.) Pennington 



North American Flora, v.9, pt 4, p. 277. 1915. 



Epicr. Myc. 386. 1838 (As Marasmius epiphyllus Fr.). 

 Ann. Rep't N. Y. State Cab., 23:175. 1872 (As Marasmius sub- 

 V e n o s u s Peck ) . 



Pileus membranous, plane, at length subumbilicate, 2-T0 mm 

 broad ; surface plicate, rugose, milk-white, often becoming light 

 brown in age, margin not striate ; lamellae adnate, few, rather 

 narrow, often veinlike, distant, venose-connected, white : spores
