146. A. rivulosus Pers, — Pileus at first inclining to flesh-colour, 

 becoming white when dry and older, sometimes becoming fuscous, 

 fleshy, somewhat thin, convexo-plane then depressed, never umbo- 

 nate ; when young moderately regular, 2.5-5 cent. (1-2 in.) broad, 

 at length 7.5-10 cent. (3-4 in.) broad, repand, undulato-lobed, 

 sprinkled with very delicate and closely adpressed and evened, 

 at length truly rijuoso-rivulose, whitish villous down; margin at 

 first involute, villous ; flesh compact, white. Stem 2.5-5 cent. 

 (1-2 in.) long, about 6-8 mm. (3-4 lin.) thick, stu_ffed\N\\h a. spongy 

 pith, at length also hollow, tough, elastic, equal, somewhat 

 fibrillose, becoming white. Gills obliquely acute behind, not 

 equally attenuated, adnate then somewhat decurrent, broad, some- 

 what crowded, flesh-colour then becoming white. 



Odour pleasant, taste mild. Sometimes solitary, sometimes caespitose. 

 Changeable in colour and size. It can be properly recognised only in rainy 

 weather. When casspitose it is larger, with undulato-lobed pileus, &c., so 

 that it might be easily mistaken for var. diffot-mis of A. cerussatus.
