The North American Species of Pholiota

England. Sept. 22, 1951. The reliable characters of distinction are the
very small pale colored spores, glutinous scales on the stipe, and yellowish young gills. The macroscopic features even to the glutinous scales
apply to more than one taxon here in this group in North America.

Illustrations: Text figs. 248-250.
Pileus 3-6 cm broad, convex, becoming more or less plane, at length
umbonate, yellow, the disc somewhat ferruginous, viscid; with small,
ferruginous-fulvous, adpressed, drop-like scales; margin appendiculate
from veil remnants. Context whitish to yellowish, or yellow under the
cuticle; taste bitter.
Lamellae adnate, yellow then bright rusty or ferruginous, close or
crowded, rather narrow, edges at first white-crenulate.
Stipe 2-5 cm long, 3-8 mm thick, yellowish above, brownish and
fibrillose-squamulose below the peronate-fibrillose fugacious ring, equal,
solid.
Spores 6.5-9 X 4.5-5.5 /u, smooth, no germ pore evident; shape in
face view ovate to elliptic, in profile obscurely inequilateral to beanshaped; color rusty cinnamon in KOH, in Melzer's reagent slightly
redder, wall thin (-0.25 u).
Basidia 26-32 X 6-7 pu, 4-spored, narrowly clavate, yellowish in KOH
and Melzer's reagent. Pleurocystidia rare and inconspicuous, 27-42 X
5-7 /x clavate-mucronate, (possibly merely basidioles). Cheilocystidia
abundant, 28-60 x 5-12 p, elongate-clavate to capitate, rarely somewhat
fusoid-ventricose or septate, hyaline thin-walled, smooth, yellowish in
Melzer's reagent. Caulocystidia present as a few clavate end-cells arising
from surface hyphae over apex.
Gill trama of subparallel-interwoven hyphae 4-15 (20) /t diam., cells
often short, thin-walled, yellowish to hyaline in KOH, smooth, content
colloidal and ~ hyaline in KOH causing hyphae to stand out boldly,
in Melzer's reagent the content cinnabar-red to reddish orange; subhymenium of narrow (3-4 f/) subgelatinous closely packed hyphae
hyaline in KOH and yellowish in Melzer's reagent. Pileus cutis of subgelatinous mostly ochraceous hyphae (in KOH) 2.5-4 /u broad and more
or less radially disposed (not in a compact pellicle), hypodermial region
not distinct from context. Context hyphae (in KOH) with colloidal
content, scattered hyphal cells with a refractive metallic body (crystal?)
resembling the inclusion in typical chrysocystidia (in KOH), hyphal
