Agaricus (Collyhlci) distortus, Fries, Epicr., p. 8i; Cke.,. 

 Hdbk., 13. 64; Cke., Ilhistr., pi. 282, Go2. 



On rotten pine trunks ; also on heaps of leaves, &c. 



Allied to C. fusipes, but closely lesembling C. hiitijracea ;: 

 known by the broad, lax pileus ; thin, fragile, contorted 

 stem, and the gills becoming spotted with reddish-brown. 



Collybia butyracea. Bull. 



Pileus 2-3 in. across, flesh rather thick at the disc, thin 

 elsewhere, soft, somewhat hygrophanous, dingy then white ;; 

 convex then expanded and more or less umbonate, dry, even, 

 glabrous, reddish-brown and shining as if oiled, becoming 

 2^ale and dull, dingy ochraceous or whitish when quite dry;. 

 gills slightly adnexed, almost free, thin, crowded, crenulute, 

 white, never becoming spotted or stained with brown or 

 red; stem 2—3 in. high, 3-4 lines thick at the base, IJ lines 

 at the apex, base incrassated, equally attenuated upwards, 

 striate, rufous, usually glabrous, but sometimes downy all 

 over, with a rigid cartilaginous cuticle, stuffed or hollow; 

 spores elliptical, 7-9 X 4-5 fx. 



Agaricus hutijrar.eus, Bull., t. 572; Cke., Hdbk., p. 64;. 

 Cke., Illustr., pi. 143. 



On the ground in woods. 



Solitary, or usually growing in troops; closely resembling; 

 C. distorta in many respects, but more constant in form, and 

 differing in the gills not becoming spotted with red. 



Pileus 1^ in. broad, subcarnose, convex, expanded, umbo- 

 nate, subviscose, of a livid ochre or dull green, when quite- 

 young livid-brown ; the margin subrufesent, but a portion 

 below the umbo soon grows pale, so that the pileus appears 

 of four colours. The umbo is always dark, but sometimes 

 the rest of the pileus is pale rufescent or ochraceous, margin 

 occasionally striate ; flesh white mottled with rufous. Gill&- 

 close, free, not ventricose, rounded, edge rather uneven 

 and notched. Sporules white. Stem lJ-2 in. high, |r in. 

 thick below, somewhat twisted, smooth, slightly striate,- 

 downy at the bulbous base, stuffed white within, the outer 

 coat being of quite a different structure and rufescent.
