Pilzes und die braun-violette der Sporangienwand mit gewissen 
Peronospora-Arten der Gruppen Intermediae und Undulatae fast 
vollkommen uebereinstimmt, muss der Pilz nach der gegenwart- 
igen Guttungsbezeichnung doch wegen der Keimung mittelst 
Schwarmsporen zur Gattung Plasmopara gestellt werden.

The articles in the July No. of the Annales Myco- 
logici (1904) are as follows: Salmon, On Erysiphe graminis 
DC., and its adaptive parasitism within the genus Bromus (fort- 
setzung) ; McAlpine, Some Misconceptions concerning the Ured- 
ospores of Puccinia pruni Pers., and Note on the Arrangement 
of Teleutospores in Puccinia pruni Pers.; Sydow, Neue und 
kritische Uredineen; Rehm, Ascomycetes Americae borealis, II; 
Hecke, Ueber das Auftreten von Plasmopara cubensis in Oest- 
erreich; Oudemans, Puccinia veratri; Trotter, Intorno all’ Uro- 
myces giganteus Speg.; Bubak, Vorlaufige Mitteilung ueber In- 
fektionsversuche mit Uredineen im Jahre 1904. 
D. McAlpine exposes some Misconceptions concerning the 
Uredospores of Puccinia pruni Pers. in Annales Mycologici, Juli 
1904 (2:344-8), showing that there are not two kinds as often 
maintained — with and without thickened apex — but one kind 
only, always too with apical thickening. He also shows the 
fallacy of claiming here the existence of a Uromyces amygdali— 
for such spores represent merely the Uredo stage of Puccinia 
pruni. Two nuclei were detected in the uredospores — one only 
in the teleutospores. The author also noted a ball-like arrange¬ 
ment of the teleutospores. 
The Polyporaceae of North America, VIII — Hapalo- 
pilus, Pycnoporus and new monotypic genera — an article'of 14 
pp. in the August No. of the Bulletin of the Torrey Botanical 
Club, by William Alphonso Murrill, contains notes on the species, 
keys to the species, synonyms, distribution, also a synopsis of 
the genera treated in articles I-VIII of this series. The new 
genera proposed are : Abortiporus, type Boletus distortus Schw.; 
Cyclomycetella, type Boletus pavonius Hook.; Cycloporus, type 
Cyclomyces greenei Berk.; Globifomes, type Boletus graveolens 
Schw.; Nigrofomes, type Polyporus melanoporus Mont.; Poro- 
nidulus, type Boletus conchifer Schw.
