25. M. graminum Berk. — Pileus scarcely exceeding 6 mm. 

 (3 lin.) broad, very pale rufous, the furrows paler, umbo brown, 

 nearly plane, nmbonate, sulcate. Stem quite smooth, shining, 

 black, white above. Gills attached to a free collar, few, somewhat 

 ventricose, even, with veiny interstices, cream-coloured. 



A most elegant species, and quite distinct from M. rotula. 

 On grass. Uncommon. July-Sept. 



Stem 2.5 cent. (1 in.) and more long. Gills 6-8 only. Fr. Name—gramen, 



grass. On grass. Berk. Out. p. 222. t. 14./. 8. C. Hbk. n. 674. S. Mycol. 

 Scot. n. 639. Fr. Hym. Eur. p. 477. Ag. Lib. cxs. 119. 



26. M. androsaceus Fr.— Pileus 4-6 mm. (2-3 lin.) broad, 

 whitish or somewhat fuscous, membranaceous, arid, somewhat 

 umbilicate, smooth, striate. Stem 4 cent. (i}4 in.) and more 

 long, filiform, horny, fistulose, very tough, equal, very smooth, 

 black, contorted and striate when dry. Gills adnate to the stem 

 (without a collar), simple, distinct, distant, whitish. 



There are two forms : on deciduous leaves the pileus is whitish, deeply 

 umbilicate, plicate, the mycelium (on oak-leaves) creeping within the sub- 

 stance of the leaf; on perennial leaves (Pinus silvestris, Juniper, here and 

 there on bark) the pileus is scarcely umbilicate, more even, somewhat fuscous, 

 and the mycelium commonly free. 



On leaves, twigs, &c. Common. April-No v. 



The umbilicus is darker. Name — a?idrosaces, a zoophyte : madrepora 



acetabulum Linn. Perhaps from its form. Fr. Monogr. ii. p. 229. Hym.

27. M. splachnoides Fr.— Pileus somewhat membranaceous, 

 convex then expanded and umbilicate, smooth, striate. Stem 

 horny, fistulose, smooth, shining, red ("becoming fuscous"). 

 Gills somewhat decurrent, crowded, simple and anastomosing, 

 white. 



Inodorous. Allied most closely to M. androsaceus ; differing however in 

 the red stem, and somewhat decurrent, more crowded gills. 



Among pine-leaves. Cabalva, Foxley. Oct. 



By an error in 'Hym. Eur.' it is represented as being of the habit of 

 M. perforans. See ' Epicr.' and 'Monogr.' Name — splachnum, a moss 

 (<xn\dyxvov, applied to a cryptogamic plant) ; elSos, appearance. Splachnum- 

 like. Resemblance not apparent. Fr. Hym. Eur. p. 478. Monogr. ii. p.
