list of the words defined, there is a Synopsis of the terms under 
the subheads of General terms applied to the surface as a whole; 
Terms applied to the Margin in particular; Surface Markings 
and Surface Coverings. For beginners and amateurs this is the 
best glossary we have yet seen. 
In the Proceedings of the Linnean Society of New 
South Wales, 1904, Part 4, November 30th, we find an account 
of the bacterial origin of Macrozamia Gum, by R. Greig Smith. 
The author says there can be no doubt that the gum exuded from 
the plant is produced by a bacterium which he describes and names 
as Bacillus macrozamiae. 
R. Greig Smith reports a Yellow Race of Bacillus 
Pseudoarabinus, Proc. Lin. Soc. N. S. W. 1904, Part 4, Nov. 30, 
which, though found on the plant next named, has probably noth¬ 
ing to do with the production of the mucilage of the quince. The 
white and yellow races of Bacillus pseudoarabinus were obtained 
as such and preserved their respective colors for a year under 
laboratory conditions. 
Verhandlungen des Botanischen Vereins der Provinz 
Brandenburg, Vol. 46, 1904, contains the following mycological 
contributions: P. Hennings, Zwei neue Cudonieen aus der Um- 
gebung Berlins [Cudoniella buckowensis P. Plenn. n. sp., an ab- 
gestorbenen Carexhalmen zwischen Sphagnum; Cudoniella oster- 
wald P. Henn. n. sp., auf feuchten Sandboden. zwischen Junger- 
mannia bicuspidata und Aigenuberzugen) ; Phaeosphaereda Mar- 
chantiae P. Henn. n. sp. [auf abgetrockneter Marchantia poly- 
morpha] ; Otto Jaap, Erster Beitrag zur Pilzflora der Umgegend

The Yearbook of the United States Department of 
Agriculture for 1904 (issued in 1905) contains many interesting 
papers, but one only is mycological, namely, Plant Diseases in 
1904, by W. A. Orton — his customary annual list. 
A Key to the Stipitate Polyporaceae of temperate 
North America is given by William A. Murrill in the February 
and March Nos. of Torreya, 1904. It is carried out to the species 
— and the usual full diagnoses given serve well for use in identi¬ 
fication of specimens. Dr. Murrill’s refined genera will be under¬ 
stood by the following which we copy: 
Surface of hymenophore covered with reddish-brown varnish. .Ganoderma 
Surface of hymenophore not as above — 
Tubes hexagonal and radially elongated.Hexagona 
Tubes not as above — 
Stipe compound .Grifola 
Stipe simple — 
Context white — 
Plants fleshy, terrestrial .Scutiger
