lationship of Sclerospora is to emphasize its affinity to the Per- 
onosporacese rather than to the Albuginacese, and to indicate its 
specialized rather than primitive character. Sclerospora, as 
shown by the combined evidence of the double investment of its 
oospore, the character of its conidiophores, and its cytology, 
probably separated early from the main line of the Peronospor- 
aceae, at a time much later than the divergence of the Albu- 
ginaceae from the Peronosporaceae. 
Uredine^l Exsiccate et Icones, Fascicle iv, J. C. 
Arthur and E. W. D. Holway, Dec. 1902, contains 49 packets, 
with a like number of photo-engraved drawings and heliotype 
reproductions from photographs, representing 15 species. It is 
needless to commend this admirable and to every student of 
Uredineae indispensable set of specimens. The photographs 
(heliotype reproductions) have heretofore been unequalled. The 
signs the authors use here and elsewhere are, O for spermatia, I 
for aecidiospores, II for uredospores, III for teleutospores, and 
X for amphispores; the same printed in small type indicate few 
sori or the spores scattered among other spores. 
A MONOGRAPH OF THE (7) NORTH AMERICAN SPECIES OF 
Ganoderma, by William Alphonso Murrill, is given in the Bull. 
Torr. Bot. Club, 29:599-608, October 1902. It is the “lucidus” 
group of Polyporus; the genus Ganoderma being established by 
Karsten in 1881, based upon the laccate character of pileus and 
stipe. The range was extended in 1887 by Patouillard to include 
all forms of Polyporaceae with colored spores, adhering tubes 
and shining crusted pilei. Mr. Murrill describes as new five of 
the seven species included in the monograph. 
Cephalothecium roseum has proved to be a true 
Parasite and the cause of an apple rot of great economic im¬ 
portance, according to H. J. Eustace, Science, N. S. 16:747-8, 
Nov. 7, 1902. In some sections thousands of barrels of apples 
have been ruined by it. Fusicladium dendriticum, unusually 
common, ruptures the epidermis and thus furnishes a means of 
entrance for the Cephalothecium.
