phyte merely and of no economic importance. The author states 
that it is a wound parasite and can not go through sound epider¬ 
mis ; hence its association with Scab. 
In the Transactions of the Massachusetts Horticul¬ 
tural Society for the year 1902 (pp. 64-73) is printed an inter¬ 
esting lecture by M. B. Waite, delivered Feb. 15, 1902, on the 
Fungous Diseases of Fruits. After a brief general discussion of 
the significance of diseases, he outlines the principal facts of a 
few of the most important orchard diseases. 
H. & P. Sydow give in Annales Mycologici No. 2, a list 
of about a dozen and a half fungi, proposed as new in the last 
two years, bearing names that have been previously used — there¬ 
fore replaced by new names. Of these only one (Cercospora ses- 
silis Ell. & Ev. Jour. Mycol. 8:71, June 1902) appeared in an 
American periodical. Didymostilbe P. Henn. antedates Didym- 
ostilbe Bres. et Sacc. (the same fungus) 26 days. Another case 
of a similar generic name applied to the same species is Allescher’s 
Microdiplodia (1901) and F. Tassi’s Microdiplodia (1902). 
A Key to the North American species of Lentinus — I, 
by F. S. Earle, is given in Torreya, 3 135-8, March 1903. The 
following sections are recognized in the key: Pleuroti, Resupinati, 
and Mesopodes including Criniti, Lepidei, Pulverulenti, Cochleati, 
and Cornucopioides. 
On a Canker of the Oak, (Quercus rubra), Professor 
M. C. Potter, University of Durham Philosophical Society, Pro¬ 
ceedings, vol. II, part 2, 1902, gives an account of a Stereum for 
which the name of Stereum quercinum is proposed. 
The Brown Rot Disease of the Redwood, by Hermann 
von Schrenk, forms a part of U. S. Dept. Agr. Bureau of Forestry, 
Bulletin 38 (pp. 29-31, pi. X & XI), but at present no one fungus 
can be determined to be the cause of this disease. It is surmised 
that the cause may be the same as that of the Pine Rot of Libo- 
cedrus decurrens, namely, Polyporus libocedris. 
Uromyces occidentalis Dietel n. sp., on Lupinus latifolius, 
L. argenteus, and L. sileri, is published in Beiblatt zur Hedwigia, 
421(98), and other species are critically considered in the same 
article — the title being Ueber die Uromyces-Arten auf Lupinen, 
von P. Dietel. 
Annales Mycologici, Vol. I. No. I, Jan. 1903 (pp. 1-96; 
pi. I-II), H. Sydow, contains the following articles: Vorwort; 
Ueber die auf Leguminosen lebenden Rostpilze und die Verwandt- 
schaftsverhaltnisse der Gattungen der Pucciniaceen (P. Dietel) ; 
Diagnosen neuer Uredineen und Ustilagineen nebst Bemerkungen 
zu einigen bereits bekannten Arten (H. & P. Sydow) ; Notae 
mvcologicae (P. A. Saccardo) ; Ueber eine neue Pilzkrankheit
