nights. Most other fungi in the woods had collapsed from the frost by
noon that day.
Pholiota muelleri (Fr.) P. D. Orton is described as having gills with
edges yellower than the faces at times, but Orton describes the scales of
the pileus as being fibrillose rather than gelatinous. He also describes the
spores as 5-7 X 3-4 /.

Pileus 4-7 cm, broad, convex expanding to nearly plane, margin at
first appendiculate with veil remnants, viscid to glutinous when young
or wet, ground color bright pale yellow ("Pinard-yellow" to "empireyellow") bruising to olivaceous ("sulphine-yellow"), on aging ferruginous
from the center out, surface at first decorated with concentrically arranged amber-brown ("amber-brown") scales about 3 mm in diameter
and triangular near cap margin but subconic on the disc; margin even.
Context white when young, flavescent moderately thick and pliant.
Lamellae adnate to adnate-emarginate with a tooth, 5-7 mm broad,
crowded, when young pallid to "olive-buff," becoming avellaneous and
finally clay-color, edges minutely floccose.
Stipe 4-8 cm long, 5-11 mm thick, equal to a flange-like enlargement
at base and base surrounded by a radiating mass of olive-yellow to tawny
pubescence, solid, whitish within at first, lutescent or finally fulvous
below, the annular zone covered with closely set projecting yellow scales
which became tawny in age, naked above the veil line. Veil pale yellow,
almost cortinate.
Spores 6.5-8 (9) X 3-4 /u, smooth, apical pore present but minute,
apex not truncate; shape in face view oblong to elliptic, in profile oblong
to elliptic (often narrower by 0.3,/ in profile than in face view); color
in KOH dull tawny, not much change in Melzer's reagent; wall about
0.25 /A thick.
Basidia 26-33 x 6-7.5 /x, 4-spored, narrowly clavate, hyaline in KOH
in properly dried material, yellowish in Melzer's reagent. Pleurocystidia
30-46 x 7-11 /u, subclavate to narrowly ovate-pedicellate or nearer fusoidventricose; wall thin smooth and hyaline; content dark bister to very dull
brown and filling the cell, coagulating in drying but not forming a dis
