2 Marasmius prasiosmus Fr. 



Epicr. Myc. 376. 1838. 



Pileus submembranous, soft, campanulate, convex, expanded, 

 obtuse, gregarious, 2-4 cm broad ; surface rugulose-sulcate, glabrous, 

 whitish or yellowish, disk darker; context with a strong odor of 

 onions ; lamellae attached, subcrowded, narrow, white ; spores white, 

 12-15 by 3-4 /*; stipe fistulose, pallid, glabrous above, subtomentose 

 and thickened downward, pallid, then rufous or fuscous, 5-8 cm 

 long, 2 mm thick. 



Upon old leaves in woods. 



3 Marasmius confluens (Pers.) Ricken 



Blatter. Deutsch. 72. 191 1. 

 Fries, Epicr. Myc. 88. 1838 (As Collybia confluens (Pers.) (Fr.) 



Pileus subfleshy, dry, broadly convex to plane, cespitose, 1.5-3.5 

 cm broad ; surface smooth, pinkish brown, becoming yellowish 

 brown or almost white in dry plants; margin thin, often involute 

 even in old, dried plants; lamellae narrow, crowded, free, 

 remote, white or slightly discolored in age; spores 7-8 by 3-3.5 fx\ 

 stipe equal, enlarged at the apex, hollow, brown, covered every- 

 where with dense white tomentum, bases of several plants bound 

 together with dense whitish mycelium, 4-12 cm long, 2-5 mm thick. 



Among dead leaves or moss. Common. 



This species has generally been considered as a Collybia although 

 it was recognized as having the characteristics of a Marasmius. 

 Peck (Ann. Rep't N. Y. State Mus., 49:61) says " They revive 

 under the influence of moisture and thereby indicate an intimate 

 relationship to the genus Marasmius." Ricken 1. c. describes this 

 species as having cystidia which are lacking in our plant. 



4 Marasmius archyropus (Pers.) Fr. 



Epicr. Myc. 37&- 1838. 



Piles subfleshy, tough, convex to plane and depressed, gregari- 

 ous or cespitose by the union of several plants by masses of my- 

 celium at the base, 2-3 cm broad; surface alutaceous, pallascent, 

 often becoming nearly white, glabrous ; margin thin, involute, except 

 in the mature plants, even, smooth ; context moderately thin, tough, 

 whitish; lamellae white, yellowish when dry, adnexed, crowded, 

 narrow ; spores 8 by 4 fi ; stipe pale reddish, usually appearing gray
