The North American Species of Pholiota

they are pale tawny. Pleurocystidia none found. Cheilocystidia abundant,
32-44 x 6-9 pi, fusoid-ventricose with short to long necks and subacute
apex, if elongated the neck often flexuous to moniliform (with irregular
swellings and constrictions).
Basidia 14-17 x 6-7 p/, 4-spored, hyaline in KOH. Spores 7-8.4 x
4.4-5 pt, smooth, apical pore distinct and apex somewhat truncate, ovoid
to ellipsoid, pale tawny is KOH.
Smith noted that the gills were neither as close nor as narrow as in
P. vernalis. The diagnostic features of the species are the subferruginous
young pileus, broad close gills (as contrasted to narrow crowded gills in
P. vernalis), whitish gills when young and the whitish stipe. Singer and
Smith (1946) confused this species with P. vernalis and published a very
cumbersome description under the latter name which encompassed a
number of taxa. At present, we suspect with Overholts (1927) that P.
marginella is rather common on conifer wood and debris in the mountains both in eastern and western United States but our data on individual collections are not complete enough for critical comparisons. For
further comment see P. vernalis.

Pileus 1-4 cm broad, broadly convex, expanding to nearly plane,
surface glabrous, hygrophanous, brown when moist, fading to pale dingy
clay-color, not viscid.
Lamellae close, adnate-seceding, narrow to moderately broad, dull
cinnamon when mature.
Stipe 2-6 cm long, 1.5-3.5 mm thick, cespitose, base coated with
appressed whitish mycelium, becoming very dark brown from base up
to apex; cortina scanty, apex pruinose.
Spore deposit near clay color. Spores 6-7.5 (8) x 3.8-4.2 (4.5) pL,
smooth, apex somewhat truncate from the apical pore; shape in face view
narrowly ovate to suboblong, in profile slightly inequilateral, wall about
0.25,u thick; in KOH the walls dull cinnamon, in Melzer's reagent about
the same color as in KOH or paler.
Basidia 18-23 X 5-7 JL, 4-spored, hyaline in KOH, narrowly clavate.
Pleurocystidia none. Cheilocystidia abundant, 28-42 X 7-11 Pt subcylindric to subfusoid or somewhat fusoid-ventricose, apex subacute to
