Dec. 1902] Notes from Mycological Literature 
203 
scription of this interesting species, Rhodora, 4: 3-5, January 
1902. In the same number (pp. 5-7) Hollis Webster also com¬ 
ments on the same and adds some notes as to Volvaria bomby- 
cina, “as beautiful and striking agaric as the woods produce,” 
and V. speciosa, grayish and viscid, said to be edible, reported 
poisonous by Bresadola. 
Dr. L. O. Howard reports in the Yearbook of the U. S. 
Department of Agriculture for 1901 (pp. 459-470) some experi¬ 
mental work with Fungous Diseases of Grasshoppers, but he 
says it is “nothing more than a report of progress” and that “the 
results obtained so far do not justify very sanguine hopes.” The 
fungi more or less successfully used were: a species of Mucor 
(work in South Africa), perhaps also Empusa grylli, and Sporo- 
trichum globuliferum (S. A. and U. S.). 
Albert Schneider reports (Botanical Gazette, 34:109-113, 
July 1902) success in obtaining Rhizobium mutabile in artificial 
culture media, and illustrates the forms seen on a full-page plate. 
Tubercles were used from young seed-grown plants of Melilotus 
alba. The organism develops slowly, is essentially aerobic, de¬ 
void of all active motion, undergoes great change in form and 
size, apparently does not develop true spores. 
Clathrus columnatus, a tropical species of Phalloid, 
was found in November last by Mr. F. Silsbee at Lawrence, 
Massachusetts, as reported by H. Webster in Rhodora, 4:134-5, 
June 1902. 
Monographia Uredinearum by P. & H. Sydow, Vol. I, 
Fasc. I, has just been issued from the Leipzig firm of Fratres 
Borntrager. The work contemplated by these uredinists, and of 
which the first Fasciculus is a part, shall “in erster Linie der Sys¬ 
tematic dienen, also vor allem das Auffinden und Bestimmen einer 
Art so viel als moglich erleichten soil;” accordingly the division 
into subgenera or sections (Eupuccinia. Heteropuccinia, etc.) have 
not been regarded, but all of the species are arranged according 
to the host plants. The 192 pages issued includes the Puccinia 
on Compositae, the genera of hosts arranged in alphabetical order. 
The descriptions are Latin, the additional notes in German. Many 
figures drawn by the authors, illustrate the rarer species. They 
are outline figures, not shaded or colored, and all drawn to the 
same amplification, namely, about 480. Fast samtliche Diagnosen 
sind nach Untersuchung von original-exemplaren entworfen. As 
to the synonomy, the authors say: Auf die oft so verworrene 
Synonymik haben wir das grosste Gewicht gelegt and dieselbe 
so ausfuhrlich wie nur moglich gegeben. It is expected that 3 
volumes will complete the work, and all the parts issued in the 
course of three or four years. The first volume is to contain 
only the genus Puccinia.
