11. Coleosporium Solidaginis (Schw.) Thiim. 0, I, II, III 



Bull. Torr. Club, vol. 6, p. 216, 1878. 



The aecial stage probably represented by Peridermium montanum 

 Arth. and Kern, which is reported from California by Hedgecock 

 (Phytopathology, vol. 6, p. 64, 1916). 



Uredinia common in the bay region on Aster radulinus Gray, A. 

 Menziesii Lindl., A. chilensis Nee., and Solidago calif ornica Nutt. On

 dena (McClatchie). 



CRONARTIUM FRIES 

 Observ. Myc., vol. 1, p. 220, 1815. 



Aecia erumpent, inflated, usually forming galls. Uredinial spores 

 born singly on pedicels. Telia erumpent, scattered ; teliospores formed 

 in chains which adhere to form a cylindrical column, one-celled, 

 usually fusiform. Heteroecious. 



12. Cronartium coleosporioides (Diet, and Holw.) Arthur. 0, I, 



II, III 



Erythea, vol. 1, p. 247; K A. Flora, vol. 7, p. 123, 1907. 



The aecial stage (Peridermium Harknessii Moore) produces spher- 

 oid galls on Pinus contorta Dougl., P. Sabiniana Dougl. and P. 

 ponderosa Dougl. Widely distributed throughout the Sierras, also 

 at Mount Diablo (Blasdale and Bethel). 



Uredinia and telia on Castilleja foliolosa H. and A., Berkeley (type 

 of Uredo coleosporiodes Diet, and Holw.), also Mill Valley (Bethel) ; 

 on C. latifolia H. and A., and C. Wightii Elmer, Moss Beach (Mrs. 

 Brandegee) ; on C. miniata Dougl., Lassen National Forest (Meinicke) ; 

 on C. sp., Lake Tahoe (Bethel) ; on C. Douglasii Benth., San Mateo

Bot. Gaz., vol. 7, p. 56, 1882; Phytopathology, voL 2, p. 176, 1912. 



The aecial stage produces slight hyperthrophy of branches on 

 Pinus ponderosa Dougl. (Peridermium filamentosum Peck), Lake 

 Tahoe; on P. contorta Dougl., Lake Tahoe, Plumas County (Meinicke). 



Telia on Castilleja miniata Dougl., and according to Hedgcock not 

 distinguishable morphologically from those of Cronartium coleo- 

 sporioides, Lake Tahoe.
