‘Tuses long, darker brown than the flesh. Pores minute, regu- 
lar, rich yellow brown, when turned sloping to the light 
exhibiting silvery reflections like the pile of velvet. 
Pirgus rich dark red brown, often whitish at the edge, strongly 
marked and made very uneven by concentric ridges ; 
sometimes one stratum of the plant laidon another; 3 to 
5 inches wide, 14 to 3 inches broad. Flesh thin,

Tubes 3 ar inch or more in length, constituting almost the 
whole substance of the plant. Pores rusty brown, very minute. 
Pileus thin, leathery, or spongy, soft, adapting itself to the 
wood on which it grows, and serving as a base on which the 
tubes are erected. Bovron. Buntiarp. In M. Bulliard’s plate 
: the plants are represented as growing in great masses, and cup- 
ping up. These grew in vaults upon hewn timber. Mr. Bol- 
ton found his on dry decayed boughs of hazle. In the course 
of time the whole. plant assumes a woody texture, harder than 
cork, as is the case with a specimen sent me by Mr. Gough of 
Kendal, which grew upon the rotten branch of a plumb tree. 
The pores in this specimen form eleven concentric circles, one 
laid against the other; and it is probable that each circle is 
the growth ofa year. The pileus, or the part by which it was 
attached, does not shew any marks of a regular increase.
