17. M. angulatus B. Br. Pileus fuscous-whitish, somewhat 

 membranaceous, hemispherical then flattened, at length plicato- 

 angular. Stem 2.5 cent, (i in.) and more long, thin, rufescent- 

 grey, thickened at both ends, hairy at the base. Gills distant, 

 whitish. 



Very different from M. Vaillantii. 



On grass. Cefn, Denbighshire, above Bone-cave. 



Name angulus, an angle. From the angular pileus. B. & Br. n. 1018.

18. M. languidus Fr. Pileus 12 mm. ( l / z in.) broad, white, 

 inclining to flesh-colour or light yellow, slightly fleshy, at first 

 convex, margin involute, then more expanded and umbilicate, 



flocculose, rugoso-sulcate. Stem scarcely 2.5 cent, (i in.) long, 

 1-2 mm. ( l /2-i lin.) thick, stuffed, thickened upwards, naked, 

 pallid, becoming fuscous and commonly white villous at the 

 base. Gills adnate then decurrent, distant, connected by veins, 

 narrow, white. 



Gregarious, tough, pliant, inodorous, especially remarkable for its decurrent 

 gills. Its appearance is that of Agaric us. 



On dead leaves of grass. Coed Coch. 



Name langueo, to be weak, languid. Limp and tough as opposed to 

 brittle. Fr. Monogr. ii. p. 224. Hym. Eur. p. 473. B. & Br. n. 1017. 

 C. Hbk. n. 667. Ag. LaschBatt. t. 27. /. O. 



** Stem velvety or pruinate, with a somewhat tubercular base. 



19. M. fcetidus Fr. Pileus 12 mm. (% in.) broad, bay-brown- 

 tawny, membranaceous, somewhat pellucid, pliant, convex then 

 expanded, at length umbilicate, striato-plicate. Stem scarcely 

 reaching 2.5 cent, (i in.) long, i m. (^ lin.) thick, \\m\\}>,fistulose, 

 equal, date-brown, and everywhere velvety, inserted with a very 

 small floccose tubercle at the base. Gills adnexed in the form of 

 a ring, somewhat decurrent when the disc is depressed, distant, 

 connected by veins, yellowish-rufescent. 



Odour fcetid. There is another form differing in the colour being wholly 

 umber, and in the absence of the villous tubercle at the base. This and the 

 other plicate species differ from the Rot nice in the mycelium not being rhizo- 

 morphcid, and in the margin of the pileus being at first somewhat involute.
