Pileus convex to plane or nearly so, umbonate when young, circular in outline, 2-5 cm. 
broad, reaching 7 cm. at times; surface smooth, glabrous, sometimes rimose-areolate, 
slightly viscid in damp weather, varying from ochraceous to fulvous; margin regular, 
entire, sometimes quite thick because of the lengthening of the marginal tubes: context 
thickest at the center and gradually thinner toward the margin, yellow or yellowish-white 
for the most part, but light-pink or roseous next to the layer of tubes, darker when exposed 
to the air, acrid and peppery, remarkably free from insects; tubes adnate, at length de- 
pressed around the stem, latericeous, becoming slightly darker when wounded, tinged with 
ferruginous at the maturity of the spores, equal to or longer than the thickness of the con- 
text, mouths large, angular, unequal: spores subfusiform, ferruginous, 9-114 u: stipe 
central, slender, nearly equal, 2-5 cm. long, 4-5 mm. thick, rarely reaching 7 cm. in length 
and 8 mm. in thickness, pulverulent, slightly veined above, smooth below, usually some- 
what paler than the pileus, citrinous or flavous at the base, solid, fleshy, and yellow within.
