121. MARASMIUS ROTULA Fries. Hym. Eur. Agar- 
icus rotula Scopoli, Flor. Carn. 1772. 
Pileus membranaceous, a little convex, umbilicate, plicate, 
whitish, of a uniform color or darker on the disk. Stipe horny, 
fistulous, shining, glabrous, blackish, arising from a root-like 
mycelium, often sarmentaceous. Lamellae few, broad, distant, 
joined together behind into a free collar, whitish; spores 6-8 x 
3- 4 mic. 
Growing on fallen trunks and old leaves. Pileus 2-6 mm. 
in diameter; the stipe 2-3 cm. long, “frequently branched and 
sarmentose, with or without abortive pilei.” 
122. MARASMIUS ROTALIS B. & Br. Fungi of Cey¬ 
lon. 1871. M. Rotula, var fuscus B. & C. Fungi Cub. 118. 
Pileus hemispheric, umbilicate, sometimes umbonate, sulcate,

There are 12-18 furrows on the pileus corresponding to the same
