200 AGARICUS. 



Entoloma. mealy at the apex. Gills somewhat free, very broad, transversely 

 veined with raised ribs, undulated, but not serrated, pallid then 

 flesh-colour. 



Commonly forming large crowded clusters, very fragile, hence the irregu- 

 larity of the stem. Allied to A. sericeus, but inodorous. 



In grassy pastures. Common. Oct. 



Readily distinguished by the gills. B. & Br. Spores irregular, subglobose, 

 with a globular nucleus. B. & Br. ; 12-14x8-10 mk. B. Name costa, a

440. A. sericeus Bull. Pileus 2.5 cent, (i in.) and more broad, 

 hygrophanous, umber, becoming pale with a silky appearance 

 when dry, fleshy-membranaceous, convex then plane, obtuse, some- 

 what repand, even, smooth ; margin at the first involute, striate ; 

 flesh very thin, scissile, umber. Stem 2.5-5 cent. (1-2 in.) long, 

 2-4 mm. (1-2 lin.) thick, fibroso-fissile, fistulose> equal or thick- 

 ened M\waxd& t fibrillose t grey. Gills emarginate, slightly adnexed, 

 horizontal, equally attenuated from the stem to the margin (not 

 ventricose), grey then rufescent, even at the sides. 



Gregarious, small but slightly firm, with a strong odour of new meal, by 

 which it is readily distinguished from A, pascuus, and other somewhat similar 

 species. It is distinguished from A. pascuus besides by the form and involute 

 margin of the pileus, and by the gills being quite entire and attenuated from 

 the stem towards the margin. 



In meadows and open woods. Frequent. May-Oct.

441. A. Persoonianus Phil. & Plow. Pileus 12 mm. (y z in.) 

 broad, shining white, then becoming pale, somewhat fleshy, very 

 fragile, convex, obtusely umbonate, silky-shining. Stem rather 

 long, somewhat bulbous and solid at the base, otherwise hollow, 

 comparatively thin, 5 mm. (2% lin-) thick, piloso-squamulose on 

 the surface. Gills somewhat adnexed, crowded, 4 mm. (2 lin.) 

 broad, obovate or broader towards the apex, red-flesh-colour, but 

 rendered darker when the spores are mature. 



The bulb in our plant is much more decided than in Persoon's fig., having a 

 distinct abrupt margin, and the pileus is not so fleshy. The large angular 

 spores are as wide as the basidia, and the hymenium abounds with large 

 cystidia.
