Pileus campanulate, shghtly umbilicate, even, glabrous, 

 very thin, extreme margin sometimes slightly upturned, rich 

 tawny-yellow, 4-8 mm. across ; gills deeply decurrent, paler 

 than the pileus, very distant, thick ; spores broadly elliptical, 

 hyaline, smooth, 5 x 3 /a ; stem about 2 cm. long, slender, 

 expanding upwards into the pileus, polished, rich orange-

 Sacc, Syll. v., no. 1285. 



Pileus membranaceous, almost translucent, rather tough, 

 usually umbilicate, then infundibuliform ; margin drooping, 

 then expanded, sometimes conical and more or less papillate ; 

 glabrous, hygrophanous, striate and orange-yellow or some- 

 times brownish or quite white when moist, pale when dry, up 

 to 1-5 cm. across, usually much smaller; gills deeply de- 

 current, distant, distinct, broad, whitish ; spores elliptical, 

 4-5x2)a; stem 2-3 cm. long, very slender, coloured like
