REPORT OF THE STATE BOTANIST I914 JJ 



Upon dead leaves of deciduous trees. Not uncommon. Re- 

 ported by Peck as M. g 1 a b e 1 1 u s Peck, although the lamellae 

 are narrower not ventricose and cystidia are lacking. 



53 Marasmius rotula. (Scop.) Fries 

 Epicr. Myc. 385. 1838. 



Pileus membranous, convex, unibilicate, gregarious or subcespi- 

 tose, 3-10 mm broad; surface plicate, not polished, whitish, often 

 light brown in dried plants, disk sometimes darker; lamellae few, 

 broad, distant, joined together behind into a free collar, whitish; 

 spores 6-8 by 3-4 /x ; stipe fistulose, horny, smooth, shining, blackish 

 brown, inserted or arising from rhizomorphic strands, 2-5 cm long. 



Upon dead leaves, wood and bark in woods. Very common. 



54 Marasmius capillaris Morgan 

 Jour. Cine. Soc. Nat. Hist., 6:194. 1883. 



Pileus membranous, convex, umbilicate, 2-5 mm broad ; surface 

 plicate-sulcate, very minutely wrinkled, alutaceous to umber, white 

 at the center ; lamellae equal, broad, white, attached to a free collar ; 

 spores 8-10 by 4-5 /x; stipe capillary, very long, inserted, black, 

 paler at the apex, glabrous, shining, 5-6 cm long. 



Upon old leaves and sticks in woods. Not common. This species 

 seems to differ from M . rotula Fr. in its constantly smaller 

 size and brownish pileus with white center. 



55 Marasmius graminum (Lib.) Berk. & Br. 

 Berk. Outl. Brit. Fungol. 222. i860. 



Pileus membranous, convex to plane, umbonate, 3-6 mm broad ; 

 surface reddish white, becoming darker in dried plants, margin 

 sparingly sulcate ; lamellae free with collar, equal, distant, whitish ; 

 spores 8-9 by 4-5 /x; stipe capillary, tough, black or pallid at the 

 apex, glabrous, shining. 



Upon dead grass. Not uncommon. 



It is doubtful if this species is distinct from M. Curreyi 

 Berk. & Br. The only difference in the descriptions of the two 

 species is in the size of the spores, which are given as subglobose 

 3-4 fi for M . graminum and 9 by 5-6 /x for M . Curreyi. 

 It is very possible that the spore measurements of M . g r a m i n u m 

 are based upon immature plants.
