The Genus Galerina Earle

have considered P. autumnalis to be a synonym of G. marginata. Because of
the well formed pellicle in G. autumnalis we do not accept this conclusion.
For additional comments see G. venenata.
Smith 49425 on debris at Ashford, Washington, appears to be a form
with a fibrillose rather than membranous annulus and a darkening stipe.
In the field it was mistaken for G. sideroides. The following data were obtained from this collection:
Pileus 10-20 mm broad, convex, glabrous, viscid, tawny fading to
cinnamon buff, drying somewhat darker. Lamellae ochraceous tawny,
close, adnate, narrow. Stipe 30-50 mm long, 1.5-2 mm thick, equal or
slightly enlarged downward, pale honey color above, bister from the base
upward in age, with a superior fibrillose zone from the remains of the veil,
pruinose above.
Spores 7-9 X 4-5 Iu, inequilateral in face view, ovate in profile, dull
ochraceous tawny in KOH, with a coarsely wrinkled exosporium with a
tendency to slough off (as revived in KOH), plage sharply delimited.
Basidia 4-spored, 20-25 X 5.5-7,u, sub-cylindric, hyaline in KOH.
Pleurocystidia scattered, 40-60 X 9-15 A, fusoid-ventricose, apices acute,
hyaline, thin-walled. Cheilocystidia similar to pleurocystidia. Gill trama
interwoven, pale ochraceous in KOH. Pileus trama homogeneous beneath
a distinct gelatinous pellicle. Clamp connections present. The spore characters separate this variant from G. cinnamomea, and the gelatinous pellicle
of the pileus separates it from G. helvoliceps.
G. autumnalis is a common species variable in nearly all the characters
considered important in Galerina. The taste varies from mild to slightly
farinaceous to that of raw cucumber. The cystidia have tips which are subacute, obtuse or slightly enlarged, and may be very rare to very abundant.
The annulus is usually present on some specimens in a group, but at times
it may seemingly be absent though we have never found young caps without a veil. The spore ornamentation may be quite adherent to almost as
loose as in G. helvoliceps. In our estimation this species, G. marginata and G.
unicolor should be studied in culture and carefully compared. Almost every
region in which we collect has populations which differ to some extent in
one or two characters.
