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



Tlie aeeial stage probably represented by Peridermium montanum 

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

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



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

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

CRONARTIUM fries 

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



Aecia erumpent, inflated, usnally forming galls. Uredinial spores 

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

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

 usuallj^ fusiform. Heteroecious. 



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



II, III 



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



The aeeial stage {Peridermium Harknessii Moore) produces spher- 

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

 ponderosa Dougl. Widely distributed throughout the Sierras, also 

 at Mount Diablo (Blasdale and Bethel). 



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

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

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

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

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

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

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



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

 distinguishable morphologicallj^ from those of Cronartium coleo- 

 sporioides, Lake Tahoe.
