umbonate behind when young, 4-6 X 5-8 1.5-3 cm.; surface glabrous, at length rugose 
and slightly sulcate, laccate, lustrous, castaneous to bay; margin ochraceous, thin, sterile, 
sometimes proliferous: context punky, homogeneous, isabelline with a fulvous line adjoin-

subshining, thinly encrusted, 2-3 times shallowly sulcate, densely zonate, zones conspicu- 
ously marked with white and bay; margin subobtuse, free behind, undulate to lobed, shin- 
ing latericeous to bay, often forming a border beneath encircling the hymenium: context 
soft-corky, multizonate, avellaneous, fulvous next to the tubes, 3-5 mm. thick ; tubes indis- 
tinctly stratified, 3-5 mm. long each season, avellaneous within, becoming grayish in the 
older layers because of the white mycelium that fills them, mouths circular to slightly 
angular, whitish-stuffed wften young, regular, 3-4 toa mm., edges nearly white to grayish-

stipe tubercular, umbonate-affixed, often branched, slightly darker than the pileus, 0.5-1 
% 0.5-1.5 em.

horny radiations, slightly zonate, fulvous, 5-10 mm. thick; tubes perennial, long and 
slender, 1 cm. in length each season, smoky-fuliginous, mouths circular, 4 toa mm., stuffed
