than the measurements given in the European descriptions. 
The Sylloge gives 3—4x6—7 y. Otherwise the agreement of 
the plants with the European descriptions is close. They 
agree also with the illustrations in Fries Icon. 104 and Cooke’s 
Illust. 370. 
The chief characteristic of the plants is the very scaly 
pileus contrasted with the smooth innate fibrous stem. A 
form with a scaly stem is however given in Constantin and 
Dufour’s key. The annulus is very scanty. The gills are 
very broad, crenate and white floccose on the margin. The 
stems are nearly equal with very slight bulbous enlargement 
at the base. 
Pileus somewhat fleshy, 1 —2J inches broad, convex to 
plane, margin incurved and extending beyond the gills, 
covered with a thick floccose coat which tears into concentric 
scales composed of bundles of fibers, often squarrose, 
scales tawny on a lighter yellowish background. Flesh 
solid, light yellow. Taste mild. Lamellae adnate with a de¬ 
current tooth, very broad, light yellow becoming tawny, 
more or less crenate and white floccose on the edge. Stem 
1-2 inches long, 1-3 lines thick, fibrous but not scaly, solid 
or fistulose, curved, light yellow above becoming dark 
tawny below, equal or tapering downward, equal or very 
slightly bulbous at the base, mealy above the slight annulus. 
Spores, inequilateral, ellipsoid, 4—6x8 —10/x.

Note . The affinities of these plants are not very clear. Farlow 
in the index considers Pholiota curvipes as identical with Pholiota 
tuberculosa. The only striking difference between the two species 
as illustrated by Fries in Icon. 104, 2 and 3, is that Pholiota tuber¬ 
culosa has a beautiful round bulb at the base of the stem while the 
stem of Pholiota curvipes is not bulbous at the base. This is a 
marked difference between the plants illustrated in vol. XVII, pi. 
XLI and these plants. These agree better with Schaeffer t. 79 but 
that is considered a poor illustration of Pholiota tuberculosa. The 
bulbous stem might be a fluctuating variation but the size of the 
spores in my plants differs widely and is the reverse of the differ¬ 
ence between the spore measurements of the two species as given 
in the Sylloge.* The spores of Pholiota tuberculosa are said to 
measure 4—-5X8—10g while those of Pholiota curvipes measure 
3—4X6—7At’ Plants with such widely differing spore measure¬ 
ments should scarcely be placed in the same group. 
Both Pholiota tuberculosa and Pholiota curvipes are reported 
by Stevenson, Constantin and Dufour, Winter and Britzelmayr.
