152 BRITISH FUNGI 



purple when moist, paler when dry, -|-f in. across, smooth ; gills 

 broadly and al^ruptly adnate, rather distant, whitish, then pinkish 

 grey and powdered with the white spores ; stem slender, stuffed, 

 dark-coloured, velvety, base slightly thickened and surrounded by 

 snow-white fibres of mycelium, up to i in. long. Inodorous (spores 

 elliptical, smooth, colourless, 5x3 /a). 



Somewhat resembhng in general appearance small specimens of 

 M. fcetidus, but distinguished by the entire absence of smell. Also 

 allied to M. langiddus. Specimens collected in Mulgrave Woods 

 during the Y.N.U. fungus foray, September, 1910, constituted the 

 first British record of this species. 



On wood, twigs, etc. 



M. vaillantii. — Cap \-i in. across, thin, pliant, soon plane and 

 the disc depressed, marked with radiating ridges, whitish ; gills 

 adnate, broad, white ; stem about i in. long, thickened upward, 

 smooth, bay, the apex pale, penetrating the substratum. 



Inodorous. Small, tough, dry. M. impiidicus differs in the 

 purplish stem becoming white and velvety when dry. M. jcttidns 

 differs in colour and in the strong smell. 



On dead wood, fallen twigs, leaves, etc. 



M. splachnoides. — Inodorous. Cap 4-6 lines across, membran- 

 aceous, convex, then expanded and umbilicate, smooth, striate, 

 whitish, with a tinge of pale tan ; gills slightly decurrent, crowded, 

 simple, anastomosing, narrow, white ; stem 1-2 in. long, slender, 

 horny, smooth, shining, reddish or brownish, penetrating the 

 matrix abruptly. 



Size and habit of M. perforans, differing in the absence of smell, 

 and the white, slightly decurrent gills. 



On pine leaves, etc. 



M. curreyi. — Cap convex, then plane, very thin, coarsely striate, 

 pale rufous, the grooves paler, umbo tawny, 3-5 lines broad ; gills 

 few in number, attached to a collar round the stem, rather ventri- 

 cose, cream-colour ; stem about i in. long, slender, equal, quite 

 smooth, shining, black, apex white. 



Distinguished from other small species in this section by the 

 pale rufous cap and cream-coloured gills. 



On leaves of grass, etc. 



M. angulatus. — Gregarious. Cap |-J in. across, thin, hemi- 

 spherical, then plane, becoming plicate and more or less angular, 

 whitish with a tawny tinge ; gills adnate, narrow, paler than the 

 cap ; stem i-il in. long, slender, grejdsh upwards. 



M. calopus differs in the shining, bay stem. Closely resembling 

 M. curreyi and M. graminum, the first differs in the ventricose gills, 

 and the latter has the gills attached to a collar round the stem. 



On grass, rushes, etc.
