dant, 45-83 x 9-16 Iu, prominently projecting, broadly to narrowly
fusoid-ventricose with greatly elongated neck of uneven diameter and
apex obtuse to subacute, in KOH and Melzer's the content evenly ochraceous (rarely with solid matter), walls thin to slightly thickened (up to
0.5 pu) in ventricose part in some, smooth. Cheilocystidia 32-50 x 8-12
(18) ui, fusoid-ventricose and similar to pleurocystidia or shorter and
more obese or utriform to subclavate, hyaline to evenly pale ochraceous
in KOH. Caulocystidia none.
Gill trama of floccose parallel hyphae with hyaline smooth thin
walls as revived in KOH, merely yellowish in Melzer's reagent, cells short
to elongate, becoming inflated in age (8-15 pI); subhymenium a hyaline
gelatinous narrow zone of interwoven hyphae. Pileus cutis a thick (to
250 pu) gelatinous layer of hyphae 2-3 p. diam., with smooth or nearly
smooth walls and interwoven; hypodermial zone of narrow (3-8 p.)
orange-rusty hyphae with incrusted walls. Context hyphae 5-15 p. diam.,
thin walled, smooth, interwoven and hyaline to yellowish in KOH.
Clamp connections none. All hyphae inamyloid.
HABIT, HABITAT, AND DISTRIBUTION: On or near rotting conifer logs,
Idallo Washington and California, summer and fall.
OBSERVATIONS: This species has some characters in common with
P. Iubrica, but differs chiefly in the brown color of the veil remnants on
the pileus. This color is limited to the outer layer of the veil and shows
best on remnants left on the pileus. Those on the stipe are usually whitish
from the pulling apart of the veil layer as the stipes elongate. The stipe
elongation is somewhat like that in subgenus Bulbopodium of Cortinarilus
where the outer veil if present connects to the rim of the basal bulb and
the veil remnants on the stipe represent mostly partial veil material. See
P. lubrica and P. avellaneifolia for further comment.
