123. A. melaleucus Pers. Pileus 4-7.5 cent. (1^-3 in.) broad, 

 commonly becoming black-fuliginous when moist, then fuscous- 

 livid, becoming pale when dry, fleshy, soft, convex then flattened, 

 obsoletely umbonate, even, smooth ; flesh soft, white, not hygroph-

 striate, whitish, with darker striae. Gills emarginato-adnexed, 

 crowded, horizontal, straight, broad, more or less ventricose, quite 

 entire, white. 



Very protean and changeable in colour. The gills are not arcuato-scythe- 

 shaped as in A. arcuatus, and the flesh does not become yellow as in that 

 species. It varies with the gills becoming yellow. It must be carefully dis- 

 tinguished chiefly from A. oreinus.
