114 OUTLINES OF BRITISH FUNGOLOGY. 



Subgenus G. Colltbia. — Stem cartilaginous externally. Margin 

 of pileus at first involute. Gills not decurrent. 



* Gills tchiic, or of ci imrc colon?'. 



97. A. (Collybia) radicatus, Relh. ; pileus thin, fleshy, ob- 

 tuse, at length plane, wrinkled, glutinous ; stem tall, attenu- 

 ated upwards, rooting ; gills adnexcd, distant, Avliite. (Plate 5, 

 fig. 4.) — Huss. i. /. 15. 



On old stumps, or on sticks eovered with soil. Very com- 

 mon. The long tap-root, wa-inkled pileus, and distant white 

 gills, at once distinguish this species. Pileus 3-4 inches 

 across ; stem 6 inches high. I once gathered a white variety 

 of this, with the pileus scarcely an inch across, though per- 

 fectly developed. The colour is generally greyish-brown. 



98. A. (Collybia) longipes, Bull.; pileus thin, fleshy, co- 

 nical, then expanded, umbonate, dry, slightly velvety; stem 

 attenuated upwards, rooting, velvety; gills distant, rounded 

 behind, white.— 5m//. /. 232 ; Huss. i. /. 80. 



In the same situations as the last, but not so common. 

 When well grown, one of the most beautiful of our Agarics. 

 Pileus and stem often tinted with yellow. 



99. A. (Collybia) platyphyllus, Fr. ; pileus thin towards 

 the margin, expanded, obtuse, moist, streaked with little 

 fibres ; stem stufled, equal, soft, striate, naked, pallid, ending 

 abruptly; gills distant, truncate behind, adnexcd, white. — 

 Bull. t. 594. 



In woods, amongst leaves. Rare. King's Cliffe. Pileus 

 several inches across, umber or brownish. The form with a 

 stout, creeping, string-like mycelium, named A. repens by 

 Fries, has been found by Mr. Broome in the south of Eng- 

 land, and by myself in Denbighshire. Stem not so distinctly 

 cartilaginous as in other Collybice.
