Id woods. Distiuguislied by the deep i)urple-rcd pileus 

 and the purple or orange-red openings of the tubes. Fries 

 says that the apex of the stem is sometimes reticulated. Dis- 

 tingnislied from Boletus purjmrascens by the red or purple 

 moutlis of the tubes. A very fine form of the present species 

 was collected at Morpeth in Cumberland, presenting the fol- 

 lowing characters: — Pileus 4 in. across, convex then plane, 

 rather flexuous, margin slightly exceeding the tubes and in- 

 curved, very minutely tomentose, reddish-purple, flesh about 

 i in. thick, thinner towards the margin, j^ellow, uuchan^;e- 

 al)le ; tubes free from the stem, ventricose, ^ in. long, yel- 

 lowish-olive, becoming blue when cut, openings irregular, 

 circular and about I mm. across, or elongated up to 1 mm., 

 edges of dissepiments deep orange ; stem o in. long, ecjual, 

 but attenuated at extreme base, ground yellow, but densely 

 covered with purple spots and lines, solid, flesh yellow above, 

 becoming blue when cut, deep purple downwards; spores 

 olive, elliptical, 9x5//. 



C. Tubes red throughout their lenrfth.
