19-1. Smith 17083.
Pileus 2-3.5 cm broad, obtuse when young expanding to obtusely
camnlpanulate or finally nearly plano-umbonate in age, disc "Natal brown,"
sometimes becoming "wood-brown" to "avellaneous" (dark vinaceous
b1rown to gray-brown); margin shading off to "pale olive-buff," usually
decturved a long time; surface at first with scattered delicate yellow fibrillose scales from the broken veil; viscid to glutinous, fibrillose-streaked
beneath the slime, usually with small patches of veil tissue along the
margin. Context thick on the disc and tapered abruptly away from it,
pliant, "olive-buff" or more or less greenish watery gray; odor none,
taste mild or faintly bitterish.
Lamellae bluntly adnate but soon slightly depressed and toothed,
broad (more or less 6 mm), horizontal, subdistant (24-28 reach the
stipe, 2-3 tiers of lamellulae), "pale olive-buff" or a little more green
when young, near "buffy-brown" in age, or finally more rusty from the
spores, edges fimbriate.
Stipe 3-6 cm long, 3-4.5 mm thick, equal or narrowed below, hollow,
"chartreuse-yellow" (greenish yellow) at least at the apex, surface "seafoam-yellow" above, slightly brighter below, lower two-thirds covered by
delicate zones or patches of more or less "clay-color" fibrils which are the
darkened remains of the veil, apical region delicately fibrillose-farinose,
base delicately fibrillose-strigose.
