AGAKICINI. 115 



100. A. (Colly bia) fusipes, Ball. ; pilciis fleshy^ convex^ 

 smooth, at first evciij then frequently cracketl ; stem more or 

 less twisted and split, swollen, sulcate, rooting below, and 

 spindle-shaped ; gills adnexcd, nearly free, at length separa- 

 ting behind, connected by veins, white, then nearly of the 

 same eolom- as the pileus. (Plate 5, fig. 5.) — Huss. ii. t. 48. 



On stumps. Very common. Pileus 3 inches across. Often 

 densely csespitose, more or less rufous. Gills often spotted. 

 Very variable in size and form. An early species. A. wde- 

 matopiis, as far as the English Flora is concerned, rests upon 

 an imperfect plant of Dickson. If distinct, the decurrent gills 

 must be the principal character, in which case it could not be 

 a Collybia. This circumstance may, however, arise from some 

 peculiar condition of the pileus. 



101. A. (Collybia) mactilatus, A. and S. ; pileus fleshy, 

 compact, convex, then plane, obtuse, even, smooth ; stem 

 stout, ventricose, striate, attenuated below, white, as well as 

 the free gills. — Sow. t. 246 ; Hiiss. ii. t. 60. 



In fir-woods. Not common. Pileus 2-3 inches across, at 

 first white, then, like the stem, spotted with reddish-brown. 



102. A. (Collybia) butyraceus, Bull. ; pileus fleshy, con- 

 vex, at length expanded, moist, changing colour ; flesh turn- 

 ing white ; stem slightly stuftcd, externally cartilaginous, co- 

 nical, striate, reddish brown; gills nearly free, crowxlcd, cre- 

 nulate, white.— i?^//. t. 572. 



• In woods, especially fir-w^oods. Extremely common. Easily 

 distinguished by its greasy-looking pileus and cartilaginous 

 stem. The pileus is at first dark-bay, but as it dies exhibits 

 various pallid tints. Stem often compressed. A. conqn-essus, 

 Sow. t. 66, is very doubtful, but I believe it to be Hyyro- 

 phorus ovinus. A. concinnus, Bolt. t. 15, is described as 

 clothed with a viscid slippery fluid, and therefore cannot
