abundant mycelium which covers leaves and twigs at its base. 
Stevenson states stipe “for the most part” covered with woolly 
hairs. In our plant the hairs only cover the lower part of the stipe. 
Our plant is not so highly colored as Cooke illustrates. We do not 
present now a figure of the plant, it having been spoiled by the en¬ 
graver, but one will follow in next issue. Those who secure our photo¬ 
graphs, however, will have a splendid illustration of the plant. 
104—COTLYBIA BOREARIS, P. T. - 
Fig. 18. 
Collybia borealis, (natural size.) 
Pileus hygrophanous, convex- 
expanded, pale bay, the center 
dark rufous brown, lighter color 
when dry, obtuse, even. Gills 
cinereousfree , narrow, close. Stipe 
equal, fistulose, bay-brown, cov¬ 
ered with a uniform coat of short 
villous down. 
These specimens were caespi- 
tose at Hubbard Take, Mich., on 
fallen pine needles. It is the first 
specimen I have met of Fries’ 
Tephrophanse with cinereous 
gills. It belongs to his first sec¬ 
tion but does not seem to be either 
of his species. Peck has none 
belonging truly to this section. 
When wet the fine soft hairs of 
the stipe do not show, and in this 
state might be taken for dryo- 
phila, but when dry the different 
stipe is noticeable at once. The 
color of the gills would also dis¬ 
tinguish it. When dry the pileus 
is bibulous and under a glass ap¬ 
pears as though innately silky. 
105—p. t. species. 
llie abreviation p. t. added to the names of some of the plants 
in the previous article mean pro tempore, “for the time being.’’ It is 
added to such plants as I have been unable to determine to my satis¬ 
faction, and indicates the name I have adopted until further light is 
thrown on the subject. 
I have strong abiding faith that the greater part of our plants 
are European species, perhaps cosmopolitan species. That the reason 
we do not recognize them is due to the inaccurate plates and descrip¬ 
tions on which our knowledge of European plants is based. That the
