150 FUNGUS-FLOE A. 



central umTDO, greyish-brown, shining, margin paler and 

 distinctly striate ; gills ad nexed but remarkably ventricose, 

 almost truncate behind, very broad, 3 lines and. more, rather 

 distant, grey, slightly powdered with white; stem about 

 3 in. long and 1 line thick, straight, even, glabrous every- 

 where, livid grey, slightly hollow, distinctly cartilaginous, 

 but becoming soft, produced underground into a tapering, 

 iibrons, rooting base. 



Agaricus (Colhjh'a) protradus, Fries, Epicr., p. 97; Cke., 

 Hdbk., p. 74; Cke., Illustr., pi. 270a. 



On the ground in pine woods, &c. 



Distinguished by the very broad, rather crowded gills and 

 the rooting stem. C. plexipes differs in the free gills and 

 persistently campanulate pileus. Smell none, thus differing; 

 from G. rancida. 



Collybia tesquorum. Fr. 



Pileus up to J in. across, flesh thin ; convex, obtuse, even, 

 Wackish-brown, becoming pale ; gills free, rather distant, 

 ventricose, pale greyish-brown ; stem up to 2 in. long, ^ 

 line thick, equal, brown, apex pruinose, fistulose. 



Agaricus (Collyhia) tesquorum, Fiies, Monogr., ii. p. 290; 

 Cke., Hdbk., p. 74 ; Cke., Illustr., pi. 270b, 



Among grass in sunny places. 



Stem fistulose, 1 J in. high, not a line thick, equal, flexuons, 

 glabrous, fusci^us, apex mealy. Pileus almost membrana- 

 ceous, rather firm, convex, very obtuse, glabrous, not striate, 

 3-5 lines broad, blackish-brown, becoming joale. Gills- 

 entirely free, very ventricose, 2 lines broad, rather distant,, 

 greyish brown. Smell none. 



The broad, free gills distinguish this from all allied 

 species. (Fries.) 



Collybia clusilis. Fr. 

 Pileus ^-1 in. across, almost membranaceous ; hemi- 

 spherical then expanded, umbilicate, glabrous, hygrophanons^ 

 livid, becoming pale ; gills adnexed and with a small de- 

 current tooth, broad, almost semicircular, plane, crowded, 

 white then pallid ; stem 1 J-2 in. long, thin, soft, polished 

 and cartilaginous, glabrous, not quite straight, not rooting, 

 coloured like the pilens, then pale, base with white down^ 

 stuffed then hollow.
