HAIRY BOLETUS. 



TAB. CLXI. 



'"T^HIS is halved, adhering by one fide; it is very various in 

 ■*■ fhape and fize, being fometimes of a femicircular figure, 

 but more frequently fwollen out in lumps, of no determinate 

 lhape, lying one upon another, or prefiing to one another, and 

 united together by their lides. 



The upper furface is of a dark redifh brown, fometimes 

 fmooth, fometimes covered with a thick black or brown fhag, or 

 hairy covering, which arifes from a thick black bark ; the fub- 

 ftance within is foft and fpongy, while freih eafily tears in llips, 

 from the centre to the margin, but cuts not without much diffi- 

 culty ; when dry it becomes very tough, it catches and retains 

 fire, like the Boletus i™iarius.

The tubes are long, of the fame golden colour as the flefli. 

 The pores of a pale yellow while young, the fize various, the 

 margins ciliated, when old a dark brown, and contracted, at laft, 

 they, together with the whole plant, turn black and perifh. 



Thefe fpecimens I gathered near Bradford, on one of the 

 trunks of a remarkable tree, called the Four-Afies, November 

 the 5th, 1 791. I have received the fame from Darlington.
