MARASMIUS. 169 



There is often a blackish, creeping cord-like er rhizomor- 

 l^hoid mycelium, from Avhich individuals spring at intervals. 



On sticks, stumps, dead leaves, &c. The whole j-ear. 

 Conjmon. Pileus 1-3 lines broad, hemispherical, umbilicate, 

 and minutely umbonate, plaited, smooth, margin crenate, 

 Avhite or pale buif with a daik umbilicus. Gills broad 

 di.stant, equal, or occasionally with a few short ones of the 

 same colour as the pileus, connate behind and separating 

 from the stem so as to present the appearance of being fixed 

 to a free collar surrounding the stem. Stem setiform, 

 slightly flexuous, white above, then tawny, deep shining, 

 brown at the base, striate, fistulose, frequently branched, 

 and sarmentose, with or without abortive pilei. (Berk.) 



Marasmius graminum. Berk, f^;?^ 



Pileus 4-6 lines across, membranaceous, convex then nearly 

 plane, umbonate, deeply and distantly striate or sulcatCy. 

 tinged with rufous, the furrows paler, disc brown ; gills, 

 attached to a collar that is free round the stem, few in 

 number, slightly ventricose, cream-colour ; stem 1-2 in., 

 long, very slender, equal, smooth, shining, black, whitish, 

 above; spores subglobose, 3—4 /x diameter. 



Marasmius graminum, Berk., Outl., pi. 14, f. 8 ; Cke., Hdbk.,. 

 p. 351 ; Cke., Illustr., pi. 1129b. 



On grass, leaves, &c. 



Allied to 31. rotiila but distinguished by the pale rufescent^. 

 distantly sulcate pileus, and in growing on grass. 



Marasmius androsaceus. Fr. 



Pileus up to ^ in. across, membranaceous dry, umbilicate^ 

 glabrous, striate, whitish; gills directly adnate to the stem 

 without the intervention of a collar, simple, distinct, distant^ 

 narrow, whitish ; stem "^h—^^ in. long, very slender and 

 tough, equal, absolutely glabrous and polished, black :. 

 twisted and striate, due to contraction, when dry ; spores 

 pip-shaped, 7 X 3-4 jn. 



Marasmius androsaceus, Fries, Epicr., p. 385 ; Cke., Hdbk.,. 

 p. 351 ; Cke., Illustr., pi. 1129c. 



On fallen leaves. 



Fries distinguished two principal forms : — (^A) on deci- 

 duous leaves ; pileus whitish, deeply umbilicate, plicate ; 

 mycelium usually traversing the substance of the leaf; (JB).
