138. A. amarus Fr. Pileus 5-7.5 cent. (2-3 in.) broad, rufes- 

 cent or becoming fuscous, then becoming pale, whitish, fleshy, 

 pliant, convex then flattened, obtuse, dry, at first fibrilloso-silky, then 

 becoming smooth, rivulose, margin at first involute, thin ; flesh 

 compact but not thick, white, Stem 2.5-5 cent. (1-2 in.) long, 12 

 mm. (y z in.) thick, stuffed, tough, firm, equal, fibrillose when young, 

 becoming smooth when more full-grown, but more or less white- 

 tomentose at the base, white. Gills adnato-decurrent, crowded, 

 thin, 4 mm. (2 lin.) broad, quite entire, becoming pale white. 



Odour peculiar, taste very bitter. A well-defined species, but deceitful on 

 account of the changeable colour of the pileus. It has been noticed rufous- 

 fuscous and whitish-fuscous, paler round the margin. The pileus is often 

 unequal and repand, unpolished under a lens. 



In woody places. Holm Lacy, 1878, &c.
