Hab. On dead wood, Behar. (Dr. Hooker.) 



Pileus 7 inches across, 4 inches long, 2^ thick, gibbous, subdimi- 

 diate, covered with a thin, yellow or reddish, laccate coat; substance 

 thick, white, extremely light ; margin very obtuse, abruptly perpendi- 

 cular, zoned and striate. Pores rather deep, -gL of an inch across, 

 angular; edge obtuse, entire. 



Allied to P. porfentosusy but distinguished by its larger pores, zoned 

 and striate, sulcate margin, distinctly laccate coat, etc. It is also ana- 

 logous to P. ochroleucus, Mont., but is far lighter and more thinly lac- 

 cate, besides belonging to the P. hetuUnus alliance, and not to that of 

 F u fomentarins .

Besides the common European form, there is a large ungulate state. 

 This species grows to an enormous size on Poplars in the more 

 Northern Himalaya.

Hab. On dead wood, Khasia Mountains and Sikkim; Darjeeling, 

 (Dr. Hooker.) 



Extremely hard and rigid. Pileus 4 inches broad, expanded, thin, 

 subflabelliform, at first yellowish, and most minutely pubescent, soon 

 becoming quite smooth, dark brown, sulcated and repeatedly and 

 narrowly zoned, covered with a thick rigid crust ; substance rhubarb- 

 coloured, acquiring at length an umber tint. Pores minute, subrotund, 



yellowish-umber. 



This very distinct species has the habit of the Ceylon P.ferrtm, In 

 general it is about \ox\ inch thick, but specimens occur which are 

 ungulate, bearing some resemblance to P. igniarius. The thin forms 

 are however the more normal. The base of the pileus is often pro- 

 longed into a spurious stem.
