Phyllosticta raui (Peck) Dearness & House 



Sphaeropsis raui Peck. Bot. Gaz. 3 : 34. 1878. Phoma raui Saoc. 

 Syll. 3 : 143. 1884. Macrophoma raui Berl. & Vogl. in Atti Soc.

Examination of the type material collected in Colorado on A r t e - 

 m i s i a s c o p u 1 o r u m , by Brandegee, and communicated to 

 Doctor Peck by E. A. Rau, shows that it properly belongs in the 

 genus Phyllosticta. 



Peridermium cerebrum Peck 



An interesting form of this species occurs upon Pinus chi- 

 huahuana in Arizona, and causing an abortion of the cones as 

 shown in the accompanying plate. The specimen from which this 

 illustration was taken was collected near Canille, Ariz., by Mr Wil- 

 liam T. Doherty, July 12, 1914. 



Specimens of Peridermium carebrum hitherto colkcted 

 in this country have been caulicolous, producing enlargements of 

 woody stems. This appears to be, so far as I can learn, the first 

 collection of the species on cones. It will doubtless prove to be a 

 different species when its telial stage (some species of Cronartium) 

 becomes known. The dehiscence of the aecia is quite charactertistic.
