Fungi, Bacteria und Pathologie 331 



anschaulicht werden, zu erschweren, ist es ratsam, alle kranken 

 Kartoffeln möglichst vom Felde zu entfernen, Verletzungen beim 

 Ernten zu vermeiden und besonders alle Massnahmen zu ergreifen, 

 die einer Bakterienfäule vorbeugen können. Besondere Beachtung 

 ist auch in dieser Beziehung der Widerstandsfähigkeit der einzelnen 

 Sorten zu schenken. H. Detmann. 



Banker, H. J., A contribution to a revision of the North 

 American Hydnaceae. (Mem. Torrey Bot. Club. XII. p. 99 

 — 194. 1906.) 



This is intended to be a revision of the pileate Hydnaceae which 

 occur on the continent of North America and its adjacent is- 

 lands. The study of the distribution of these fungi is attented with 

 difficulty owing to the confusion existing regarding the identity of 

 some of the species and the scarcity of material with sufficient notes 

 to be of use. A Synopsis of the genera is given which is founded 

 chiefly upon the spore characters as it has seemed that these cha- 

 racters are very definite and fundamental. The foUowing genera and 

 species are given :
