BROWN BOLETUS. 



TAB. LXXXV. 



'"T^HE root confifts of a tuft of black fibres, iffuing from the 

 ■*■ bafe of the item. 



The ftem is at firfl globular, hard, and folid; as it advances 

 in growth it becomes oblong, and in fome fpecimens nearly 

 cylindrical, and about three inches high : it is often beautifully 

 reticulated with capillary veins, of a dark red colour, efpecially 

 towards the root; the colour is generally a red brown. I never 

 could difcover any curtain upon this plant. 



The tubes are round, the thicknefs of an hog's brittle,, very 

 clofely arranged; they are of a pale yellowifh colour. The 

 pores are round, much fmaller than in the laft fpecies, and of a 

 itrong fulvous brown colour. In this fpecies the tubes, at B. 

 are longeft in the middle, between the rim of the pileus and the 

 item, growing lhorter both outward and inward, and do not, 

 as in the Yellow Boletus, adhere to the ftenv or even touch it. 



The pileus is convex, the margin acute, the colour varies 

 from dark brown to fulvous, fawn colour, or buff of various 

 hues ; the internal fubflance is a greenilh white, but on being 

 cut, or broken, inftantly changes to a dark blue colour. 



This is a more rare plant in this neighbourhood, and does 

 not appear till September. I am forrv to rind in a late Englifh 

 Author, that fome of the characters which belong to this plant,, 

 are miftakenly applied to the Yellow Boletus.
