 tain Cedar, Sabina sabinoides (H. B. K.) Small. (Mycologia. II. 



p. 205—212. 1910.) 



The new genus and species Cyanospora Albicedrae is here 

 described as producing whitened areas on the trunk and branches 

 of the alfected trees. The areas are small or quite extensive and 

 are so common on this host that the character has been used 

 to identify the tree. The fungus, which is very probably para- 

 sitic, is common in central, and western Texas and extends into 

 Mexico. The new genus proposed is quite closely related to Ophio- 

 ceras. The most important differences between the genus Cyanospora 

 and Ophioceras are shown by means of a table. One plate with 

 seven ligures, and three additional full-page figures show the detail 

 of the fungus and its most common Symptoms upon the host.

Mentio, C, Nuovo fermento appartenente al genere Saccha- 

 romycodes. (Staz. sperim. agr. XLIV. p. 829—842. 1911.) 



In stark mit schwefliger Säure beladenen Weinmosten ent- 

 wickelt sich nach Verf. eine bisher übersehene Saccha romycodes- 

 Art, welche mit 5. Ludwigü verwandt ist. Sie gedeiht bei einem 

 Gehalt von 800 mg Schwefeldioxyd pro 1 und bildet bis 10°/ Al- 

 kohol, ersetzt daher in stark geschwefelten Mosten die Ellipsoideus- 

 rassen, welche von einem Gehalt von 200 mg Schwefeldioxyd im 

 Liter schon gelähmt werden. Sporen bildet die neue Saccharomy- 

 codes- Art bef 90° C. auf Gipsblöckchen in 36—38 Stunden. Früher 

 waren von anderer Seite Torida- Arten für die Gärung stark geschwe- 

 felter Moste verantwortlich gemacht worden. E. Pantanelli.
