The Genus Galerina Earle

Tahquamenon Falls State Park, Michigan, July 2, 1952. It has been collected between July 2 and Aug. 28. Known only from the type locality.
OBSERVATIONS: The stature of this species is that of G. triscopa but the
well-developed veil readily distinguishes it. The species appears to be most
closely related to G. pseudocamerina in the characters of spores and cheilocystidia, but differs in having a peronate veil and usually in being annulate, as well as in its habitat, on hardwood logs.
MATERIAL EXAMINED: Smith 37025; 38355; 39045-type.
35. Galerina pellucida (Murrill) Smith & Singer, Sydowia 11: 449.
1957.
Naucoria pellucida Murrill, Mycologia 4: 78. 1912.
Illustrations: Fig. 53 (cheilocystidia).
Pileus 7 mm broad, thin, conic to plane with an obtuse umbo, surface
bay to latericious on the umbo, testaceous-striate between the umbo and
margin, dotted over the surface with translucent gelatinous pearly white
droplets or specks.
Lamellae adnexed, ventricose, distant, pale testaceous, marked with
droplets like those on pileus surface.
Stipe 10 mm long, 0.5 mm thick, cylindric, equal, smooth, pallid
above, bay below.
Spores 7-9 X 5-6 j, bright rusty cinnamon, roughened over all except
the basal part of the suprahilar area, Basidia 16-20 X +_- 6, hyaline, 4 -spored. Pleurocystidia none seen. Cheilocystidia abundant, 24-36(50) X
4-7 / (at base) X 2 / in the flexuous neck, hyaline, agglutinated on edge as
if viscid. Epicutis of pileus giving rise to numerous pilocystidia similar to the
cheilocystidia (gelatinous and decumbent so as to give the impression of thin
gelatinous pellicle). Pileus trama orange in KOH. Clamp connections
present.
HABIT, HABITAT AND DISTRIBUTION: On wood at New Haven Gap,
Jamaica,Jan. 4, 1909. Murrill 763-type (N.Y.)
OBSERVATIONS: The aggregations of pilocystidia no doubt account for
the droplets described by Murrill. This fungus, in its pigmentation both
when fresh and when revived in KOH, reminds one of Gymnopilus, but the
tendency for the suprahilar depression to become smooth, and the resemblance to G. triscopa cause us to place it here. It is outstanding in either genus
because of the cystidia.
Smith examined Murrill's number 763 and obtained the data presented in our description of the microscopic characters. Since the part of the
type studied by Smith offers a logical explanation for the gelatinous dots
emphasized by Murrill in his original description, we are assuming that
we have studied the specimen that Murrill described, and which must,
therefore, be regarded as holotype. Dennis (1953), however, has given a
different interpretation of the type, in which the cheilocystidia are described
as Conocybe-like. In his description, he gives the character of the cap surface
