The North American Species of Pholiota

refractive in KOH), content homogeneous or in some ochraceous-colloidal or merely not reviving well and both ochraceous and reticulate.
Cheilocystidia 30-50 X 8-14 /, utriform to subfusoid, thin-walled, smooth
except for crystals and debris around apex in some, content yellowish to
hyaline, (in either KOH or Melzer's sol.). Caulocystidia none.
Gill trama a floccose central area of parallel to subparallel hyaline
to yellowish hyphae (in KOH) with short to elongated thin-walled
colorless to smooth walls, the cells short or elongated; subhymenium of
interwoven hyphae, gelatinous in KOH. Pileus epicutis a gelatinous layer
of appressed-interwoven ochraceous-incrusted hyphae 3-5 a/ diam.; hypodermium of floccose hyphae 4-10 ut diam. with heavy, orange-rusty incrustations producing a highly pigmented region. Context hyp)hae ocllraceous-pallid in KOH, hyphae 5-14 /t diam., cells inflated, walls mostly
smooth and thin to slightly thickened (swelling slightly in KOH),
inamyloid. Clamp connections present.
HABIT, HABITAT, AND DISTRIBUTION: On debris around redwood logs,
Orick, Calif. Dec. 14, 1937, Smith 9393, type. IDAHO: On conifer wood,
Smith 54021.
OBSERVATIONS: The walls of the pleurocystidia vary from tlin to over
1 /t thick, so the species is placed in this section. It's outstanding field
characters are the ferruginous color at first, white gills becoming wood
brown, and the stipe readily staining yellow. It is very close to P. velaglutinosa but that species has a greenish yellow context, and greenish
yellow stipe apex in addition to the gelatinous outer veil.

Pileus 3-6 cm broad, convex to expanded, viscid (Murrill says dry),
subfibrillose, pale-fuscous, ferruginous in the center, margin thin, somewhat folded and uneven, not striate. Context thin, yellowish; of mawkish
flavor.
Lamellae sinuate, tawny-yellow to pale-fuscous, inserted, crowded,
rather narrow.
Stipe 4-6 cm long, 2-4 mm thick, concolorous, cylindric, curved,
fibrillose, solid, tough.
Spores 5.5-7.5 x 4-5 Ap, smooth, apical pore present but minute,
shape in face view mostly ovate but a few subelliptic, in profile somewhat
inequilateral, color in KOH dark tawny, paler in Melzer's reagent, wall
about 0.25 /u thick.
Basidia 17-21 (25) x 5-7.5 /x, mostly 4-spored, obese to subutriform,
yellow in KOH and Melzer's reagent. Pleurocystidia 45-80 X 6-12 (rarely
shorter) and up to 20 /x broad, fusoid-ventricose, apex obtuse, wall smooth
or with some solidified gelatinous material adhering in places, wall thin
