hyphae 3-5 p. diam., incrusted with rusty brown zones, rings and spirals,
scarcely gelatinous revived in KOH; hypodermium of more compactly
interwoven hyphae 4-8 u diam., and highly colored (orange-rusty) from
incrustations and wall pigment. Context hyphae closely arranged, thinwalled, somewhat translucent in KOH (as if subgelatinous) and pale
yellowish. Clamp connections present.
HABIT, HABITAT, AND DISTRIBUTION: On mossy soil among chips and
woody debris, Mt. Gretna, Penna. Sept. 15, 1924. C. H. Kauffman, type.
OBSERVATIONS: In stature this species is not too unlike P. scamba and
the possible relationship is enhanced by the thin fibrillose veil. It differs
from P. scamba in smaller spores, longer cystidia and a more cinnamon
colored pileus with darker squamules of velar material decorating the
cap surface near the margin. It is named in honor of its finder, Dr. C. H.
Kauffman.

Pileus 1-2 cm broad, more or less conic and umbonate, then expanding-convex, disc natal brown to near vinaceous-drab, elsewhere paler,
veil squamules present at first, then glabrous, viscid, margin even. Context thin, yellow.
Lamellae adnate-decurrent, yellow at first, then "buckthorn brown,"
close, broad or medium broad, edges uneven to fimbriate.
Stipe 3-4 cm long, 2-4 mm thick, pale yellowish, with scattered
fibrils or squamulose, equal, hollow. Veil copious, yellow.
Spores 7-9.5 x 5-6.5 /u, smooth, apical pore minute but distinct
(NA 1.4 ob.); ovate to subelliptic in face view, in profile elliptic to
obscurely inequilateral; color in KOH rusty brown, revived in Melzer's
reagent more cinnamon; wall about 0.25 /, thick.
Basidia 25-35 (37) x 7-9 /., 4-spored, narrowly clavate, yellowish to
yellowish hyaline in KOH and more yellowish in Melzer's reagent.
Pleurocystidia 43-80 x 9-15 ut, fusoid-ventricose, the neck tapered to a
subacute apex, smooth or with some debris adhering (in KOH), walls
thin to thickened up to 0.5 /A, content homogeneous. Cheilocystidia
similar to pleurocystidia but usually shorter. Caulocystidia none.
