face appear almost granulate or muricate, tlie yellow back- 
ground of the pileus shows in the cracks. Lamellae adnexed^ 
yellow, becoming rusty. ; Stem concolorous, stuffed or hollow, 
densely clothed with scaly fibers which are more or less squar- 
rose, with tufts of bright yellow mycelium at the base. Annu¬ 
lus slight of the character of that of the Squarrosae. Spores 
4-5x7-8/a. 
The plant is reported from Michigan by Longyear. 
IV. Small plants with an hygrophanous pileus and a mem¬ 
branous annulus. 
The plants are closely related to the Pholiota togularis type 
but grow on logs and stumps. 
18. Type of Pholiota marginata. 
Pholiota marginata, Batsch. Pis. LIV and LV. 
MARGINED PHOLIOTA. 
The plants are common on decayed logs in damp woods late 
in the autumn. In our region they are usually almost even on 
the margin of the pileus and very rarely sufficiently striate to 
justify their name. In this respect they agree with the Hew 
York type which Peck has described as Pholiota marginella. 
The forms are very various as the illustrations show but we have 
not been able to separate any of the allied species such as Pho¬ 
liota unicolor or Pholiota mutabilis. The plants in PI. LIV", C 
closely resemble those in Hard’s photograph of Pholiota uni¬ 
color but they do not agree with the plant figured in Flora 
Danica. 
Pileus watery brown or honey colored, from incurved to 
convex or expanded, smooth, margin even or slightly striate, 
sometimes recurved. Lamellae adnate or decurrent toothed, 
watery cinnamon becoming rusty ochraceous. Stem equal or 
slightly tapering upward, hollow, sometimes inflated, more or 
less white pruinose, fibrous striate, somewhat mealy at the 
apex and white velutine at the base. Annulus membranous, 
usually adhering to the stem but sometimes to the margin of
