38 Journal of Mycology [Vol. 14 



Wilson, Guy West. 



In the September No. of the Journal of Mycology may be 

 found "An historical Review of the proposed Genera of Phy- 

 comycetes, I, Peronosporales ;" the genera being arranged 

 chronologically, with the type species, the synonyms, the 

 homonyms, and other information. Those listed as tenable in 

 this order are : Albugo, Basidophora, Bremia. Chlorospora, 

 Kawakamia, Peronospora, Phleophythora, Phytophthora, Plas- 

 mopara, Pseudoperonospora, and Sclerospora. 



Smith, Erwin F. 



Dr. Smith takes issue with Howard S. Reed in statements 

 relative to "The Parasitism of Neocosmospora" — this title used 

 by both authors in articles in Science. "Inference versus fact," 

 is the key to the situation — /. e. many inferences in the first 

 article are declared by Dr. Smith to be unwarranted, for example, 

 that the ginseng-fungus belongs to the genus Neocosmospora; 

 that the ginseng-fungus and the watermelon-fungus (first de- 

 scribed by Dr. Smith as Fusarium niveum) are identical; that 

 the watermelon-fungus can enter the plant only when a way has 

 been opened for it by other fungi, e. g., by Thielavia. etc. Be- 

 sides the discussion and criticism, some experiments are reported 

 indicating that the ginseng-fungus and watermelon-fungus be- 

 have differently and are probably identical organisms. 



Rick, J. 



An important paper, "Contributio ad monographium Agari- 

 cacearum et Polyporacearum Brasiliensium," is published by Dr. 

 J. Rick, in Volume VI, 1907, II part. Series Botanica, of 

 Broteria. Tliis is based on prolonged exploration and study in 

 that region, and the installment in question contains 186 species, 

 10 of which are described as new. Many in the list enumerated 

 are cosmopolitan — a further illustration and justification of the 

 view of Lloyd and Bresadola as to wide distribution of most 

 species.
