143

Stipe 4-6 cm long, 1.5-2.5 mm thick, equal, cartilaginous, pallid to
sordid yellow above, soon dull rusty brown below, thinly appressedfibrillose to glabrous, apex pruinose, base surrounded by white mycelium.
Spores 9-11 x 5.5-6.3,L, ovate to elliptic in face view, elliptic to
slightly inequilateral in profile, smooth, pale tawny in KOH and very
sligltly redder in Melzer's, apical pore small and apex only obscurely
truncate, wall about 0.5 /i thick.
Basidia 23-27 x 5-6.5 a, 4-spored, clavate to subcylindric, hyaline
to yellow in KOH. Pleurocystidia 44-58 (64) x 8-12 /i, scattered, fusoidventricose to narrowly clavate-mucronate, projecting beyond the basidia,
usually with tle refractive content of chrysocystidia. Cheilocystidia 24-32
x 5-8 /x, ventricose to subcylindric, hyaline, content homogeneous, thinwalled, abundant.
Gill trama subparallel, the cells equal in width throughout their
lengtl, pale yellow in KOH; subhymenium cellular but very thin and
indistinct. Pileus epicutis a thin pellicle of narrow gelatinous hyphae
2.5-4 /u diam.; hypodermium of enlarged cells, yellow in KOH like
hyphae of the context. Clamp connections present.
HABIT, HABITAT, AND DISTRIBUTION: Solitary to scattered on moss in
conifer forests, New York, Idaho, Washington and Oregon: Smith
24133, 23160, and 24477 from Oregon, Smith 71086 from Idaho, and
Imshaug 987 and 994 from Washington in addition to the type of
Nalcoria hun idicola have been examined.
OBSERVATIONS: This species differs from P. elongata in having a
gelatinous pellicle over the pileus and in the longer pleurocystidia, in
fact tlhe latter are unusually long for chrysocystidia.
Stirps Elongata
Pileus moist but not viscid, aspect of bog-inhabiting Psilocybe species
(stipe long and slender).
