obscurely angular, in profile obscurely inequilateral to bean-shaped, wall
slightly thickened, apical pore present but minute.
Basidia 18-22 X 5-6 Fu, 4-spored, hymenium yellow in H,O fresh
and as revived in KOH. Pleurocystidia none. Cheilocystidia 26-35 X
9-22,, with yellow walls in H2O fresh and as revived in KOH, narrowly
clavate to nearly vesiculose, wall slightly thickened irregularly (appearing as if somewhat ornamented).
Gill trama hyaline or yellowish in H20 fresh, hyphae yellow in KOH
on sections but hyaline as seen individually, walls thin and smooth to
minutely asperulate, cells greatly elongated and 6-15 ru wide. Pileus cutis
a trichodermium the hyphae separating into fascicles to form squamules,
cells more or less inflated (15-20 /ut wide), walls thin to somewhat thickened, rich reddish cinnamon in KOH, ornamentation fine but readily
visible (not in the form of coarse plates and patches), terminal cells
often cystidioid. Clamp connections present. All hyphae inamyloid.
HABIT, HABITAT, AND DISTRIBUTION: Gregarious on hardwood logs,
Talhquanenon Falls State Park, Mich. June 22, 1955. H. E. Bigelow
(Smith 49607, type).
OBSERVATIONS: This species differs from P. granulosa in that the stipe
did not darken to a deep rusty brown from the base upward-and old
basidiocarps were present in the collection-the gills are broad and become ventricose, and the terminal cells of the trichodermial hyphae show
a tendency toward having thick walls in some hyphae of a squamule. The
veil is rudimentary. Smith 66977 gave an olive black reaction with
FeSO4. Apparently this is typical of the species, but the type was not
tested when fresh.
