Having given the minute descriptions of the three new species, the 

 author remarks that Collinsiella tuberculata Setch. et Gard. is probably 

 a young and sterile form of a plant closely related to Ecb. Willeana, if 

 not identical with it. K. Okamura.

 auf die Essiggährung. (Deutsche Essigindustrie. Jahr- 

 gang VII. Heft 29—30. 1903.) 



Besprechung der bisherigen Arbeiten über Alkohol- und Essig- 

 gährung, die Thatsache, dass todte Essigbakterien noch etwas Essigsäure 

 aus Alkohol bilden, wird besonders erörtert und aus der Annahme einer 

 Essigoxydase ziemlich weitgehende Folgerungen gezogen.

 ments with List of Species and Hosts for North 

 America. I. (Journal of Mycology. IX. Dec. 1903. p. 244 

 —257.) 



This is a summary of the results in North America in „an 

 alphabetical arrangement including authors, host-species furnishing 

 material for inoculation, species of Uredineac used, host-species on which 

 successful inoculations have been reported, and the Uredineous species in 

 their several stages that have been obtained by the cultures".
