REPORT OF THE STATE BOTANIST. 109 
MILLIUM EFFUsUM, L. 
A tall glaucous-leaved form, is plentiful in woods in the Boreas river 
valley in Minerva, Essex county. 
PELLZA GRACILIs, Hook, 
About the entrance of a limestone cavern, Minerva. The presence 
of limestone appears to be a necessity to this rare little fern. Although 
there are many localities in the Adirondack region which seem favor- 
able to its growth; I have never observed it there except in the imme- 
diate vicinity of limestone, and as this is in limited quantity and scattered 
stations, this fern occupies there very isolated and limited localities. In 
the station mentioned it was in company with Aspidium aculeatum Sw. 
v. Braunii. 
WoopwarpiA VirRGINICA, Si, 
Abundant in a marsh neer Karner. 
AGARICUS STIPITARIUS, Fr. v. SETIPES. 
Stem elongated, straight, very slender, three to four inches long, 
scarcely as thick as a knitting needle. Caroga. July. Specimens of 
this species revive on the application of moisture, thus indicating a 
close relationship to species of Marasmius. 
AGARICUS CLAVICULARIS, FY. 
This species is quite variable with us. Three or four forms or 
varieties were found growing under balsam trees in one locality in 
Caroga. Var. albus is wholly white. Var. cinereus has the pileus and 
stem pale cinereus; this is the most common. Var. filipes has the pileus 
small, two or three lines broad, and the stem very slender or filiform. 
When moist the stem is viscid, and in taking it from its place of growth 
the fingers are liable to slip from their grasp before the plant yields 
from its attachment to the ground, but when dry it is taken without 
difficulty. ‘The pileus is not viscid, and by this character the species 
may be distinguished from A. vulgaris. 
Acaricus Leatanus, Berk, 
This beautiful Agaric is common in the woods of all our hilly or 
mountainous districts, growing most frequently on dead trunks of beech, 
but often on those of other deciduous trees, In a single instance it 
was found growing on decaying wood of hemlock. 
AGARICUS FIBULA V. CONICUS. 
This singular variety has the pileus conical, not umbilicate, sometimes 
papillate. Mossy prostrate trunks in woods. Caroga. July. 
AGARICUS ATROCRULEUS, FY. 
I have not yet found the plant with blue colors. It is brownish with 
us and villose with grayish densely tufted hairs, sometimes inclining to 
a cervine hue. On poplars. Karner. Sept. 
AGARICUS RHODOPOLIUS, fr, v. UMBILICATUS. 
Pileus convex, umbilicate, 1 to 2 inches broad; lamelle subdecur- 
rent; stem elongated, slender, containing a small cavity. Karner. Sept. 
A slender variety growing with the ordinary form, but appearing quite 
unlike it.
