353. A. fibula Bull. Pileus 4-10 mm. (2-5 lin.) broad, normally Omphaii 

 orange-yellow, becoming pale when dry, hygrophanous, mem- 

 branaceous, hood-shaped then expanded, commonly umbilicate 



and at length wholly infundibuliform, smooth, striate when moist, 

 even when dry. Stem 2.5 cent, (i in.) and more long, stuffed 

 when young, then fistulose, bristle-like, weak, smooth, but often 

 pubescent under a lens, of the same colour as the pileus. Gills 

 deeply decurrent, distant, distinct, broad, whitish. 



Very delicate but tough. The stem is sometimes firmer, tense and straight. 

 The pileus is sometimes conical and papillate. The colour varies, becoming 

 fuscous and wholly white. Mich. Gen. t. 73. f. 6. In alpine regions it is 

 sometimes firmer (Fl. Dan. t. 1071. f. 2). 



In mossy ground. Common. Aug.-May. 



Fries notes that it is found plentifully in burnt places. Spores 3x2 mk.

 constant form. Fr. Monogr. i. /. 193. Hym. Eur. p. 164. S. Mycol. Scot.
