746. A. mastiger B. & Br. Pileus about 2.5 cent, (i in.) 

 broad, dark rich brown when moist, umber-tan when dry, some- 

 what fleshy, at first nearly cylindrical, obtuse, then conico-cam- 

 panulate, with a strong mammiform umbo, repand, not striate, 

 margin straight. Stem 7.5 cent. (3 in.) or more long, 3-4 mm. 

 (i>-2 lin.) thick, fistulose, attenuated upwards, white, smooth 

 or fibrillose and furfuraceous, pale umber within. Veil none. 

 Gills affixed, ascending, rather narrow, umber, edge paler. 



As the plant dries the stem acquires the tint of the pileus, but pale. This 

 fine species is allied to A. conopileus, but differs in many respects. The dark 

 colour and mammiform apex are very striking.

 adfixed, ventricose, distinctly violaceous then blackish. 



There are many forms, such as with the pileus tan-colour, and reticulato- 

 wrinkled with raised ribs. It is easily confounded with A. gracilis.
