The Genus Galerina Earle

sterile, color cinnamon-buff to "ochraceous tawny" and striate; flesh soft
and delicate, odor none.
Lamellae narrow (linear), not extending to the cap margin, distant,
ascending and only touching the apex of the stipe, pinkish buff, edges
even.
Stipe 20-25 mm long, 0.5 mm thick, pallid above and faintly pruinose, cinnamon-buff downward, naked over lower part.
Spores 8-11 X 5-6 IL (4-spored) or 11-14 X 7-8.5 i (1- or 2-spored),
ovate in face view, somewhat inequilateral in profile, a fair percentage distinctly calyptrate, plage smooth and distinctly bordered, remainder of wall
smooth to slightly wrinkled, ochraceous tawny in KOH or a little darker.
Basidia 4-spored (2- and 1-spored also). Pleurocystidia scattered, clavate
to vesiculose, 26-34 X 12-20 pi, thin-walled, some present which are similar to cheilocystidia (1-spored basidia may simulate pleurocystidia).
Cheilocystidia variable, 30-50 X 4-12 ps, neck 2-5 p, apices enlarged in
some and 4-5 p, diam., some cylindric-capitate, some ventricose at the
base and with flexuous neck and enlarged apex, also some clavate cells up
to 18 p in diam. present. Gill trama ochraceous. Pileus trama with a thin
non-gelatinous pellicle. Clamps present.
HABIT, HABITAT AND DISTRIBUTION: On a mossy redwood log, Trinidad,
California, Dec. 10, 1956, Smith 56556-type.
OBSERVATIONS: This and G. macquariensis are the only species, to our
knowledge, which show both pleurocystidia and a fair percentage of calyptrate spores. The stature of G.filiformis is that of G. subfiliformis. Because of
this combination of characters it is important to place the species on record
even though known only from the type locality. Since it seems to be related
to species of section Calyptrospora, and since the pleurocystidia are rare, it
is treated here; however, arguments could be advanced for placing it in
section Physocystis.
