Harper—Additional Species of Pholiota. 403 
2. Pholiota luxurians Fr. PI. XVI. 
Pholiota luxurians has the same structure and shape as 
Pholiota aegerita but the colors are darker with more red 
and yellow. Old plants turn black. The pileus is both squam- 
ulose and cracked. The spores are alike in color and shape 
but average slightly larger, 4—6x7 —10 p instead of 
4— 5x7— Op. The plants are larger and coarser in every 
way. 
Fine specimens of this species grew on maple stumps at 
Geneseo, Ills., in October. Some of the pilei were eight inches 
in diameter. The shape of the stems varies as in Pholiota 
aegerita, long or short, equal or enlarged at the base or taper¬ 
ing downward. Many of the plants were caespitose. The 
photograph was made from plants collected at Sumner, 
Wash. They grew on top of a maple log and had short 
stems, tapering downward. The areolae on the pileus are 
seen to be covered with fine scales as in Leeper’s photo¬ 
graphs of Pholiota aegerita. 
Pileus variable in size, sometimes very large, irregular, 
convex and gibbous to expanded, even on the margin, smooth 
and silky or somewhat squamulose, rimose cracked, reddish 
yellow becoming darker and the whole plant blackening with 
age. Flesh thick whitish to yellowish and finally black. 
Lamellae broad, rounded adnexed or decurrent according 
to the position of the pileus, becoming ochraceous-ferrug- 
inous with spores, reddening and blackening with age. 
Stem variously shaped, thick, smooth, with a thick evanes¬ 
cent annulus, colored like the rest of the plant. Spores 
ferruginous 4—6x7 —10 p. 
Plants single or caespitose. Stems sometimes grown to¬ 
gether at the base. On logs and about stumps in autumn. 
THE PHOLIOTA CURVIPES GROUP 
1. Pholiota curvipes Fr. PI. XVII. 
The plants photographed were found on rotten logs 
at Geneseo, Ills., in autumn. I have followed Peck in re¬ 
ferring them to Pholiota curvipes Fr. They agree with Peck’s 
description in N. Y. State Mus. Bull. 122, p. 154, except 
that they average a little larger. The size of the spores 
5— 6x8—10 p is exactly the same as Peck’s measurements. 
Peck calls attention to the fact that the spores are larger
