2 Marasmius prasiosmus Fr. 



Epicr. Myc. zy^i. 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 /x; 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. ^2. 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 /u; 

 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 

 si>ecies as having cystidia which are lacking in our plant. 



4 Marasmius archyropus (Pers.) Fr. 



Epicr. Myc. 378. 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 /a ; stipe pale reddish, usually appearing gray
