The Genus Galerina Earle

closest to G. vittaeformis f. tetraspora but differs in having nearly smooth spores
and very few pleurocystidia.
191. Galerina pubescentipes Smith & Singer, sp. nov.
Illustrations: Fig. 216 (pleurocystidia).
A Galerina karstenii affini differt sporis 9-12 X 4-5 ti; pileo stipiteque
ochraceobrunneis, stipite ex integro pubescente ex caulocystidiis; basidiis
bisporis; cellulis terminalibus epicuticularibus dermatocystidioideis, sparsis
in superficie pilei. Gregatim ad lignum coniferarum, leg. A. H. Smith,
53374 (MICH) in Idaho.
Pileus 4-7 mm broad, obtuse to convex, becoming broadly convex,
surface glabrous, moist, hygrophanous, ochraceous tawny and striate moist,
cinnamon buff faded.
Lamellae close to subdistant, moderately broad, ascending-adnate,
ochraceous tawny, edges fimbriate.
Stipe 15-25 mm long, 1 mm thick, equal, nearly concolorous with cap
varying to darker (but often as dark at apex as at base), pubescent overall
from caulocystidia, veil absent.
Spores 9-12 X 4-5 /s, narrow and slightly inequilateral in profile,
narrowly ovate to nearly oblong in face view, many obscurely angular in
face view, pale ochraceous tawny in KOH, pale reddish tawny in Melzer's,
very minutely roughened but plage smooth and distinct as seen under oil.
Basidia 2-spored. Pleurocystidia abundant, 50-80 X 9-14 j, thin-walled,
hyaline, smooth, apices acute to subacute, gill trama subregular, yellowish
in KOH. Pileus trama yellowish in KOH, pilocystidium-like hyphal endcells scattered over surface of cap. Epicutis of pileus of radial nongelatinous
hyphae. Clamps present.
HABIT, HABITAT AND DISTRIBUTION: Gregarious on a conifer log, Papoose
Creek, Seven Devils' Mountains, Idaho, Sept. 12, 1956. Smith 53374-type.
OBSERVATIONS: The nearly smooth spores distinguish this species from
G. vittaeformis, but there is also a difference in width which in turn is expressed in the shape.
MATERIAL EXAMINED: Smith 53374-type.
192. Galerina vinolenta (Berk.) Smith & Singer, comb. nov.
Agaricus vinolentus Berkeley, Hook. Joum. Bot. & Kew Gard. Misc. 4: 131.
1852.
Galera vinolenta (Berk.) Sacc. Syll. Fung. 5: 861. 1887.
Pileus 8-13 mm broad X 8-11 mm high, conic-campanulate, with
obtuse apex, over one-third to one-half of the radius sulcate or striate,
vinaceous cinnamon to ochraceous brown.
Lamellae rather distant and broad, ascendant-adnate, said to be
vinaceous (?).
