PEZiZA PUBIDA B. & C. 
L 
A. P. MORGAN. 
From the Linnean Society’s Journal, Vol. XXXI, page 492, 
I extract the following reference: 
Peziza (§ Sarcoscypha) Semitosta, B. & C., Macropodia 
semitosta. Sacc., Peziza pubida, B. & C., Macropodia pubida, 
Sacc., Exsiccati, Ellis & Everhart, N. American Fungi No. 2740, 
Ellis N. American Fungi No. 1269, Rab.-Winter Fung. Eur. 
No. 3275. 
The spores of this species are described as “smooth, often 
guttulate, elliptical, ends narrowed, 28-32 x 12 mic.” 
Fred Jay Seaver, in the Discomycctes of Eastern Iowa, de¬ 
scribes the spores of Macropodia pubida (B. & C.) Sacc. as 
'“fusiform, rough, 38-42 x 10.” In An Annotated List of Iowa 
Discomycetes Mr. Seaver states that Peziza Morgani Massee is 
identical with Peziza pubida B. & C. of Ellis’s N. A. Fungi 
No. 1269. He states further that the specimen in Rabenhorst- 
Winter Fungi Europab No. 3275 is different ; he says it contains 
“spores which are elliptical, rough and only 15x8 mic.” 
There is always surmise as to the amount of “straddle” each 
expert may allow to spore-measurements. It is also constantly 
occurring that two or more species are mixed in the same num¬ 
bers of the various exsiccati. 
At any rate it would appear that the numbers of Peziza 
pubida B. & C. in the collections at Kew are quite different from 
the corresponding numbers in the collections of the gentleman 
in Iowa. 
A NEW SPECIES OF SYNCHYTRIUM. 
j • J. J. DAVIS. 
While examining leaves of Scirpus atrovirens Muhl. with a 
hand lens I was surprised to observe the presence in some of the 
leaves of a Synchytrium. The host plants were 011 the border of 
a button bush swamp in Kenosha county, Wisconsin, and further 
search revealed the presence of the parasite in one or two simi¬ 
lar situations in the vicinity. It produces little distortion of the 
host and it requires a sharper eye than mine to see it without a 
magnifier. Attempts to secure the germination of the resting 
spores have not succeeded beyond the conversion of the spore 
contents into globular bodies about 20 /x in diameter — presum¬ 
ably zoosporangia.
