fractive; hyaline; subhymenium a poorly defined layer of subgelatinous
hyphae (on mature gills). Pileus trama with a thick gelatinous pellicle
of hyphae 2-8 /u diam., content ochraceous to brownish in KOH, the
layer dull reddish cinnamon near surface, yellow to hyaline in midportion; hypodermial region not sharply distinct from context. Context
hyphae interwoven, cells with slightly thickened to thin walls (2 double
lines if thickened), smooth. Clamp connections present. All hyphae
inamyloid.
It will be noted that no pleurocystidia with colored content (brown
to red) were found in this specimen, but that typical chrysocystidia were,
though in some the inclusion was not too sharply defined. In addition
the caulocystidia were voluminous. If proved constant this combination
of features may be indicative of an additional species. We refrain from
describing another species at this time because we do not have sufficient
data on the caulocystidia of the western American specimens and because
we have seen both only in the dried condition.

Pileus 4-10 cm broad, broadly convex, in age margin recurved, surface thinly viscid from a pale yellow pellicle (near "warm buff") over
this, around disc are appressed fibrillose patches as squamules which
darken to dingy brown, slowly the pellicle becoming darker yellow (near
"ochre-yellow") and in age checking to produce minute squamules over
