external resemblance to almost all white Mycenae and is very rare; 
Peck says in the latter report: “The species has been detected but 
once." I found it in a tamarack swamp. 
Both Dr. Peck and I were greatly puzzled to name the genus to 
which a plant belonged that I found first in 1910 growing upon and 
around a pile of decayed white birch. It had many of the character- 
istics of a Collybia; it looked like a Mycena; also bore some resem- 
blance to an Omphalia. The doctor wrote January 11, 1911: “It 
hovers on the confines of Collybia, Mycena and Omphalia, and I think 
better be left till we can settle at least the genus.” Finally he placed 
it in the genus Omphalia as O. maura Fr. I am not quite reconciled 
to this determination, having a strong predilection in favor of consid- 
ering it a species of Collybia. It is a small plant variable in color and 
structure from water white to fuliginous and deeply umbilicate to 
even; itis without odor and of no pronounced taste. 
September 16, 1913 I found very fine plants of what I consider 
Armillaria ponderosa Pk. It is a very noticeable plant because of the 
veil becoming lacerated and adhering in shreds to the stem and margin 
of the pileus. My plants were very light yellowish. See N. Y. State 
Mus. Rep. 43, p. 41. 
Eccilia flavida Pk. was very common during 1912 and 1913. It 
varies very much in stature and color. It is smooth and slimy, and 
when seen after the gills have assumed the prevailing color of the 
genus presents a very pretty sight. The pileus is pale yellow, ob- 
scurely striate when dry and the stem is concolorous. I find it in 
swamps under deciduous trees, usually in great abundance. 
August 4, 1913, I found two plants of one of the most interesting 
Ecciliae I have ever seen. Its especial claim to distinction lies in the 
peculiarity of the gills which are brownish-fimbriate and serrulate. 
I cannot find any species of Eccilia that agrees with my plant. 
August 4-12, 1911, I found many plants of Nolanea delicatula Pk. 
It is well named, for it is delicate in appearance and must be handled 
with the utmost care if you wish to preserve it for future reference 
and comparison. It is entirely white and found in thickly wooded 
swamps. See N. Y. State Mus. Rep. 24, p. 66. 
August 25-Sept. 6, 1913, I found many plants of what I believe to 
be a new species of Nolanea. It was growing upon decayed leaves in 
a swamp of deciduous trees in an exsiceated water hole. I made three 
eollections; the last time I picked it from under the leaves, and was
