Harper—Species of Pholiota of the Great Lakes Region. 481 
actly with any of those described. A careful study of the group 
would probably show that all the species are connected by inter¬ 
mediate forms. A number of European botanists have doubted 
whether even Pholiota praecox and Pholiota dura should be con¬ 
sidered specifically distinct. 
|4. Medium sized plants with a membranous annulus and vis¬ 
cid pileus. Type of Pholiota erebia. 
Pholiota erebia, Fr. PL XXX. 
DARK PHOLIOTA. 
The plants from which the photographs were made were col¬ 
lected at Blue Mounds, Wis., in September. They grew scat¬ 
tered or in small clusters on the ground in damp woods. More 
mature plants have been found at Xeebish, Mich. Some of 
them had the pileus slightly umhonate. The margin of the 
pileus was distinctly striate and the annulus more remote than 
in the plants from Blue Mounds. 
Pileus fleshy in the center, thin on the margin, convex, be¬ 
coming plane or somewhat umhonate, viscid, smooth or rugose 
wrinkled, hygrophanous, striate on the margin when mature, 
brown or blackish when moist, lighter when dry, fully dried 
specimens are clay color. Lamellae adnate with a tooth, pallid 
or grayish, becoming rusty. Stem equal or slightly tapering 
upward, stuffed or hollow, striate with innate fibers and squam- 
ulose especially towards the base, stems often cohering at the 
base, whitish above the annulus, darker below. Anhulus near 
the top of the stem, becoming distant, membranous, reflexed, 
sulcate, white. Spores Oxl2— 14^. . 
Massee remarks of the European plant that the pileus is some¬ 
times more or less umhonate and Stevenson says that many of 
the stems cohere at the base where they are squamulose, also 
that the pileus is often wrinkled. Our plants show these char¬ 
acters. 
"Note. The plants agree with the description of Pholiota aggericola, 
Pk. N. Y. State Mus. Bull. 122 p. 146 except in the sometimes um- 
bonate pileus, the hollow stem and the slightly longer spores. 12—14/*
