The North American Species of Pholiota

as whitish, also says that the flesh, under the cuticle, is concolorous with
the pileus. The lamellae are at first pallid, and Peck says nothing of a
yellow coloration of the young gills. He does say that he observed the
species several times in different localities always finding it constant in
its character and readily distinguishable. This has influenced us in recognizing it as a species. P. spinulifera may be the same as P. squalida, but
both should be re-collected and studied fresh before making such a disposition of it. The aspect of the basidiocarps in the type of Flammula
squalida is rather similar to those of P. prolixa but the cystidia distinguish
them readily.
Doubtful Species
Phaeomarasmius alnicola (Murrill) Singer, Schweiz. Zeitschrift fur
Plizk. 34: 61. 1956.
Crinipellis alnicola Murrill, North Amer. Fl. 9: 288. 1915.
Pileus 5-8 mm broad, subglobose to convex, rather firm. Surface
densely villose, chestnut colored, not becoming glabrous, margin concolorous, involute, strongly inflexed on drying.
Lamellae adnate, rather broad and distant, pallid, the edges finely
notched.
Stipe 5-10 mm long, 1-1.5 mm thick, clothed and colored like the
pileus, pallid and tomentose at the apex, cylindric, equal, spongy stuffed
with a cortex.
Spores 7.7-9.7 x 5.5-7.7 /u, some with a callus, pale honey-brownish.
Cheilocystidia polymorphous, 28-52 x 5-10 l. Hairs of pileus composed
"of single members" separated by normal septa with clamp connections,
incrusted by a membranous-pigment (from Singer).
On dead alder trunks, near Seattle Wash. W. A. Murrill 561 (N.Y.).
Note: We have not restudied the type for this paper because of the
very limited material and when a critical study of Tubaria is made it
will be essential to study it again. Obviously the species is similar in many
ways to P. erinacea but we exclude it from Pholiota for the present because of the spore color as indicated by Singer. The above account is
Murrill's original description with Singer's type study added.
Phaeomarasmius floridanus Singer, Schweiz. Zeitschrift fur Pilzk. 34:
59. 1956. This is a new name for Murrill's interpretation of Agaricus
curcuma.
Pileus 15 mm broad, uniformly dark fulvous, or "convexo- vel acute
conico-verrucoso..."; lamellae subdistant to distant, horizontal, broad,
nearly free, pale isabelline, edge white and fimbriate; stipe 20 x 2-2.5
mm, squamulose with erect squamules the color of the pileus forming a
sheath, apex white pruinose, base thickened; veil pallid, somewhat con
