wavy, areolately cracking in the center, grayish. Flesh 
firm, white. Lamellae sinuate with a decurrent tooth, not 
crowded, color of burnt umber. Stem somewhat flexuous, 
swollen at the base, tapering upwards, whitish pruinose, 
solid becoming hollow, striate at the apex. Annulus distant, 
membranous, persistent. Spores ferruginous brown, 4—6 X 8 
—10/a. 
In woods. On ground rich in rotten wood. June. 
Notes 1. The plants described and illustrated in Vol. XVII 
p. 477 and pi. XXVI which I doubtfully referred to Pholiota 
howeana Pk. have the more distant membranous annulus and 
stem enlarged below of Pholiota sphaleromorpha. The darker 
yellowish tint of the pileus agrees better with Pholiota sphaler¬ 
omorpha than the gray of Leeper’s plants. My field notes sug¬ 
gested that the plants were related to Pholiota praecox. There 
is little difference between Peck’s description of Pholiota howeana 
and the description of Pholiota sphaleromorpha. Dr. Peck him¬ 
self allowed considerable variation in this species. I have plants 
sent to me by Simon Davis which were indentified by Peck as 
Pholiota howeana but which were smaller, tougher and with larger 
spores than his description of Pholiota howeana calls for, 5—6X10 
— 12 yu instead of 5 — 6X8 — 10 yu. The spores of my plants were 
4—5X8—9yu and of Leeper’s 4—6X8—10yu. There is no doubt 
that all of them are close together in the Pholiota praecox-dura 
group. 
2. The plants described and illustrated in Vol. XVII p. 480 
and pi. XXIX are not as typical Pholiota dura as those shown here 
in pi. XL As was remarked the plants there described had the 
pileus thinner and more expanded with the surface very little 
cracked. The stem also was more slender and the annulus more 
perfect and entire. The spores were smaller 4—6 X 7—9 /jl. These 
peculiarities are those of Pholiota duroides Pk. which is decribed 
in N. Y. State, Mus. Bull. 122, pp. 148-149 from plants collected 
by G. E. Morris in Mass. Peck’s description reads: 
“Pileus thin, convex becoming nearly plane, glabrous or slightly 
rimose squamose in the center, varying in color from creamy 
white to ochraceous buff either wholly or in the center only. 
Flesh white. Taste mild. Lamellae thin, close, narrow, adnexed 
sometimes broadly sinuate and having a decurrent tooth, whitish 
becoming brown or rusty brown. Stem equal or nearly so, stuffed 
or hollow, glabrous, whitish, the annulus thick and cottony, 
often lacerated and evanescent, white. Spores broadly elliptic 
4—5 X 6—7 yu. 
Pileus 1—2 inches broad. Stem 1—2 inches long, 2—4 lines 
thick. 
Rocky ground. August and September. 
It is similar to Pholiota dura (Bolt.) Fr. but may be separated 
from it by its different colors, softer substance and especially
