capitate or rarely capitate, hyaline, smooth. Pileus trama homogeneous or
the cuticular hyphae narrow but non-gelatinous, mostly encrusted with a
rusty to ochraceous (in KOH) pigment. Gill trama tawny to ochraceous
in KOH, subparallel. Clamp connections present.
HABIT, HABITAT AND DISTRIBUTION: Scattered to gregarious on Sphagnum in bogs, Quebec, Massachusetts, Michigan and New York, Sept.
OBSERVATIONS: This species is analogous to G. sphagnorum but differs
distinctly in spore markings; it is the latter which indicate a relationship
to the G. cerina group. The field aspect of G. sphagnorum distinguishes it at
once from the cerina variants, but will cause confusion with G. sphagnicola
and mixed collections of these two are likely to occur if one collects carelessly. Bigelow 6219 has cheilocystidia which are "moniliform" near the
apex and in some the capitellum is drawn to a short beak.
MATERIAL EXAMINED: Bigelow 6219; 6220; 6221; (MICH). Cornell

19. Galerina payettensis Smith & Singer, Mycologia 50: 481. 1958.
Illustrations: Fig. 24 (cheilocystidia).
Pileus 10-15 mm broad, conic-campanulate, the umbo conic as in G.
triscopa, glabrous, moist, hygrophanous, "sayal brown" (dull cinnamon)
fading to cinnamon buff.
Lamellae broad, close, adnate, dull ochraceous tawny.
Stipe 10-20 mm long, 2 mm thick, equal, dull brown below, paler
above, apex dingy cinnamon buff and heavily pruinose, veil leaving a thin
annular zone but no sheath below the zone.
Spores 9-11 X 5-6.5 ju, inequilateral in profile, ovate in face view,
about 25% calyptrate, pale tawny in KOH, outer layer smooth to minutely
wrinkled. Basidia 4-spored. Pleurocystidia none. Cheilocystidia 30-46 X
5-10 X 3.5-4.5 X 3.5-6.5 /u, fusoid-ventricose and walls often flexuous,
apex subacute. Hyphae of pileus trama yellowish in KOH mostly from
incrusting pigment, cuticle a layer of radial hyphae not sharply differentiated from those of flesh. Clamp connections present.
HABIT, HABITAT AND DISTRIBUTION: On wet moss under conifers, South
Fork, Lake Fork Creek, Payette Lakes, Idaho, Sept. 17, 1956, Smith
53491-type.
OBSERVATIONS: The aspect of the fruiting bodies is that of G. unicolor,
but the fibrillose annular zone and microscopic characters rule out that
species. In microscopic characters it is closest to G. cerina var. ampullicystis,
but differs in the rostrate cheilocystidia and in the aspect of the carpophores.
In aspect it is very similar to G. psathyrelloides but that species has cheilocystidia with thicker necks and obtuse to subcapitate apices. G. triscopa differs in having smaller non-calyptrate spores.
