Peziza repanda Wahlenb. in Pennsylvania. — Mcll- 
vaine in his book “One Thousand American Fungi” (p.558) gives 
the distribution of this fungus, as : New York, Ellis; Minnesota, 
Johnson; Ohio, Lloyd; Pennsylvania, Miller. It occurs, accord¬ 
ing to him, on the ground, or on decaying wood. M. C. Cooke 
(Handbook of British Fungi II, p. 669) mentinos it as one of the 
British funguses occuring on the ground and on stumps. It 
was discovered by the writer at Sherwood, near Angora, Phila¬ 
delphia on an old rotten log in very considerable abundance. 
The specimens collected, some two or three hundred in number, 
varied in size from the diameter of a ten cent piece to one or 
two, or three inches across. The individuals were clustered, or 
disposed singly; some were saucer-shaped, others deeper and more 
bowl-shaped. The color was nearly white on the outer surface 
and a light, yellowish-brown color on the concave inner side. 
Spore Discharge in Peziza badia Pers. — A considerable 
amount of this ascomycete was found at Crum Creek, Penna., 
May 20, 1901. When gathered in the hand and held for a mo¬ 
ment, a discharge of the spores took place with a puff, like the 
curling smoke at the muzzle of a discharged gun. At intervals 
of several minutes, the same phenomenon took place until appa¬ 
rently all of the spores had been set free from the asci. 
Clitopilus abortivus B. & C.— The statement is made in an 
authoritative work on the fungi of North America, that “the fun¬ 
gus is so named because of the abortive form of it frequently 
found associated with it.” From this sentence, one would infer, 
that the normal form is more abundant than the aborted one which 
is found with it. Nevertheless in the season of 1901, the aborted 
plants were by far the most abundant in the neighborhood of 
Philadelphia. A search through several woods was rewarded 
by the collection of many specimens of the rounded, egg-shaped, 
aborted form and only a few examples of the normal gill-bearing 
fungus. 
Distribution of the Nuclei in the Feeding Plasmodium 
of Fuligo septica Gmel.— I have described elsewhere* the pecu¬ 
liar feeding habits of the plasmodium of Fuligo septica Gmel. 
Sections of the host fungus Pleurotus sapid us and of the plasmo¬ 
dium which was actively streaming over it were made and 
mounted in balsam. The material was killed and hardened in 
95 per cent, alcohol, was passed into paraffin, cut, and stained on 
the slide. Iron-haematoxylon was found the most satisfactory 
stain, the sections being left in the iron stain 4 hours and in 
haematoxylon 12 hours. A study of the sections, thus prepared, 
showed an interesting character of nuclear distribution, and 
served to prove further, that the nucleus serves as the trophic
