thick. Gills almost adnate to decurrent, moderately close, 

 sometimes branching and anastomosing, a little wrinkled, 

 apparently not easily separable from the hymenophore, bright 

 canary-yellow to greenish-yellow, often becoming darker 

 spotted when old, with a hand lens seen to be bristling with 

 cystidia. Stem 2 inches, occasionally more, high by \ inch 

 in diameter above, occasionally long and slender, slightly 

 attenuated downwards, usually stout, rarely flexous, usually 

 central, slightly fibrillose and villous, not scaly, solid, brittle, 

 pale brown and yellowish or reddish-brown just below the 

 gills, sometimes whitish or pallid with a faint brown tint due 

 to punctate points. Spores in the mass greenish-brown, 

 microscopically pale yellowish-green, elongated, somewhat 

 twisted, rather "mummy-shaped" like typical Boletus spores, 

 7'8 to 16 x 3*8 to 5 '5 /a, usually about 12 x 5*2 \x. Cystidia 

 acuminate, blunt-topped, 70 x 10*4 to 15 jut. In young speci- 

 mens, the edge is markedly turned in and the gills may be 

 crenulate and show forking and irregular buttressing folds.
