hyphae than those of the hypoderm but not gelatinous. Clamp connections
present.
HABIT, HABITAT AND DISTRIBUTION: Gregarious on Dicranum, Trout
Lake, SanJuan Mountains, Colorado.
OBSERVATIONS: The large, ornamented, richly colored, broad spores,
capitate cheilocystidia and only the most rudimentary of veils are the distinguishing characters. The field aspect of the species is that of G. cerina, but
of course the spores are very different.
Smith, 52745, Trout Lake, Colorado, Aug. 23, 1956, appears to be the
same species. In it the basidia are 4-spored, the spores 9-12.5 X 6-7.5 /, but
nearly all are ornamented over the plage area. The fact that a very few show
some indication of a smooth plage is considered significant. Clamp connections are abundant. The cheilocystidia are 20-30 X 6-8 X 2.5-3.5 X 4-6
/f and ventricose-capitate, as in G. pistillicystis. The spores are well-ornamented, broadly ovate to elliptic in face view, in profile view subelliptic
to obscurely inequilateral, and russet to "Mars brown" in KOH. This is
probably the 4-spored form of the species.

Illustrations: Fig. 52 (cheilocystidia).
Pileus 8-12(15) mm broad, obtusely conic with a + incurved margin,
expanding to campanulate or remaining convex, glabrous except for margin
which is at first appendiculate with patches of the thin veil (~ dentateappendiculate), veil remnants soon evanescent, color when young and moist
"Mars brown", soon "cinnamon brown" the margin becoming dingy ochraceous tawny and striate, hygrophanous, fading to dingy cinnamon buffor
paler; flesh concolorous with pileus, soft, taste and odor not distinctive.
Lamellae broadly adnate, broad, nearly subdistant at first, truly subdistant at maturity, ochraceous tawny (paler than pileus), edges even.
Stipe short, 10-20 mm long, 1-1.5 mm thick, equal or enlarged below,
concolorous with pileus below, apex soon fading out to almost concolorous
with the gills but in age again often darker, peronate fibrillose up to the
superior thin often mostly fragmentary annulus, pruinose above, in age
glabrescent.
Spores (7)9-10(12) X 5-6.5(7) p, ovoid to subelliptic, roughened at
least around the suprahilar plate, ochraceous tawny when revived in KOH.
Basidia 1-, 2-, 3-, and 4-spored. Pleurocystidia none seen. Cheilocystidia
24-36 X 9-11 /s, ventricose with a narrow neck and sometimes with a small
capitellum, wall ofcapitellum thickened in some and highly refractive. Gill
trama parallel, the cells short-ellipsoid, tawny to rusty brown in KOH, subhymenium not distinctive. Pileus trama dark rusty brown in KOH and
homogeneous, without pilocystidia, pigment incrusted on the hyphae.
Clamp connections present.
HABIT, HABITAT AND DISTRIBUTION: Gregarious on rotten hardwood,
