They were found in the middle of a road leading through pines. For 
the last three years I have found in a small swamp during May and 
June many plants of an interesting whitish Ascomycete, Ombrophila 
clava (A. & S.) Cooke. Its shape reminds me of a small copper rivet 
and I find it on dead leaves, often nearly or quite covered with water. 
The plant was identified by Prof. E. J. Durand. 
I find during May and June a rare species of Pholiota, P. myce- 
noides Fr. It grows in sphagnum in company with Galera sphagnorum 
Pers. The stem is very long, slender, and brittle, and in my experi- 
ence attached to the moss. It requires delicate handling if you wish 
to collect an entire plant. 
I have found in four different places for years an occasional speci- 
men of Hypholoma rugocephalum Atk. and many specimens of H. 
delineatum Pk. Both occur on decayed wood and resemble each other 
externally, but the latter may be separated from the former by its 
more narrow obtuse and smooth spores and by its broader flask- 
shaped cystidia. Dr. Peck notes the differences in N. Y. State Mus. 
Bull. No. 150, p. 83. Any collector who wishes to know the exact 
meaning of the word “rugose” cannot do better than to inspect 
very carefully the pileus of one of these fungi. 
I continue to find yearly a few plants of Pluteolus callistus and P. 
expansus Pk. They are rare plants and when in good condition as 
beautiful as they are rare. Dr. Peck in his synopsis, N. Y. State Rep. 
No. 46, p. 59, bases his distinction between these two species upon 
habit, not a good distinction in my opinion and experience. This 
past summer I found two specimens of P. expansus growing on a 
decayed maple twig in an exsiccated water hole in a swamp. The 
spores of the two species are substantially alike. 
During June and the early part of July I find quite a number of 
specimens of Marasmius varicosus Fr. Morgan does not include this 
species in his list of the North American Species of Marasmius.! 
Dr. Peck apparently has never seen the plant, for I fail to find any 
reference to it in his reports. "The purplish-brown gills growing darker 
as they dry, and the stem covered with blackish-red down half way 
up are the chief characteristics of this remarkable species. August 7, 
1911, I found many plants of Lepiota cristatella Pk., see N. Y. State 
Rep. No. 31, p. 31 and No. 35, p. 163. This plant bears a strong
