This plant bears much general resemblance to our preceding species. Bol. 
sulphurous , but is darker in colour, and of a more solid structure. E.) 
Bol. veluti'nus. Tubes brown yellow: pores pale brown: pilous 
very irregular in shape, covered with a dense pile of a silvery 
grey colour. 
Tubes bright gold colour, changing to brown yellow; half an inch long. 
Pores irregular in size, angular, light greyish brown, apparently woolly ; 
largest towards the edge of the pileus and oblong. 
Pileus a very large mis-shapen mass, covered with a stiff plushy pile con¬ 
sisting of upright hairs quarter of an inch high. Colour silvery, grey, or 
greenish, changing to brown orange, and at length to black. Sometimes 
twelve inches by seven, and tiled one over another ; the surface rather 
like a sponge, porous and cavernous: the colour varying from grey to 
green, from red brown to orange brown. Flesh several inches thick, 
chocolate-coloured, with a rich red tinge, juicy. In the younger state of 
the plant the pile on the pileus consists of all colours from pale yellow to 
deep brown orange, and when magnified appears composed of stars 
radiating from a centre. It is very beautiful seen through an eye-glass, 
but its beauty is soon destroyed on account of its tender juicy state. 
Flesh tough, fibrous, brown yellow.
