The Genus Galerina Earle

HABIT, HABITAT AND DISTRIBUTION: Gregarious on Sphagnum and other
deep moss and on needles of Larix on ground in mossy places, Quebec. It
was a common species in the Laurentide Park, Quebec during late Aug.
and early Sept., 1959.
OBSERVATIONS: This species occurs in a variety of habitats but is often
abundant on Sphagnum. It differs from G. sphagnorum in that the spores lack
a plage line, and in the duller color of both fresh and dried material. The
cheilocystidia intergrade a good deal but those of G. cainii are generally
more capitate. We at first considered this to be a variant of G. semiglobata
Singer, but the distribution seems to indicate otherwise, especially since it
is correlated with other differences such as the color and shape of the cap, and
a slight difference in spore ornamentation.

Cap 4-15(20) mm, convex then expanded-plane, sometimes papillate
or with small obtuse umbo at first or becoming slightly umbilicate when
old, tawny-honey or date-brown, sometimes paler yellowish honey at
margin, drying yellowish or yellowish ochraceous from center, striate when
moist (usually to center), striae dark brown, matt or slightly silky-scurfy in
places when dry; flesh thin, concolorous, odor none, taste none or faint
fungussy.
Lamellae adnate, often broadly so and with tooth, or subdecurrent,
from almost triangular to ventricose, pale ochraceous or yellowish honey
then deeper ochre to tawny-honey or rusty-honey, subdistant L (12)16-20
1 (0) 1-3, rather thick, sometimes forked near margin of cap or veined on
sides or interveined, edge paler flocculose at first.
Stipe 10-25 X 0.5-1.5 mm, attenuated downwards, more rarely
almost equal, often flexuose, occasionally compressed, date-brown or tawnyhoney, usually becoming chestnut, bay or dark reddish brown from base,
minutely whitish silky fibrillose striate, apex slightly whitish pruinose when
fresh, solid, spongy-fibrous inside, often rather tough, base when growing
in sand often encircled by compacted mass of mycelium and sand.
Spores ellipsoid, slightly amygdaliform, smooth sub immers., (8)9-11
(12) X 4.5-6(6.5) la, rusty ("antique brown" Ridgway) in mass. Basidia
(2-)4-spored, 36-46 X 8-10 ti. Cheilocystidia from clavate or ~ cylindric
to lageniform, 44-86 X 8-11 /, apex 5-12(17.5),L. Pleurocystidia none.
Hyphae of cap cuticle filamentous, branched, sometimes clamped, hyaline
