Mycologia 



Pages 197, 202 (My. 4: 28, 33), under no. 2, the material in hand from 

 Isle au Haut, Me., was Puc. quadriporula (P. Grossulariae), but the results of 

 infection were obtained from stray spores of Uromyces perigynius, as ex- 

 plained at page 235 (My. 7: 76) in the report of cultures for 1912. 



Pages 256, 265 (My. 8: 132, 141), under no. 4, for " Agropyri E. & Ev. 

 (P. alternans Arth )," read Cockerelliana Bethel. This distinctive species 

 was not recognized, and had not been named until long after the cultures 

 were made. 



Pages 257, 265, (My. 8: 133, 141), under no. 5, for " Anchusa officinalis," 

 read Lycopsis arvensis. 



Pages 261, 263, 265 (My. 8: 137, 139, 141), under no. 3, for " montanen- 

 sis Ellis " and " montanensis," read apocrypta Ellis & Tracy and apocrypta, 

 respectively. On page 262 three species are confused. Puccinia apocrypta is 

 not a synonym of P. Agropyri. The characters given for P. apocrypta are 

 those of the true P. montanensis, for which the type is the collection cited. 



Pages 274, 275 (My. 9: 302, 303), under no. 2, for " B. & C." read Schw. 



Summary of Cultures 



In order to give a clearer perspective of the work, and to 

 make the data more readily available, the following tabulation is 

 given of the heteroecious species that were successfully grown on 

 alternate hosts. Autoecious species, and heteroecious species 

 grown from urediniospores or amphispores only, have not been 

 included. The years are those in which successful cultures were 

 carried out. Only such synonymy is given as will account for 

 the names used at different times in the reports. The page num- 

 bers are those explained below at the beginning of the index. 

 Pages in broad faced type indicate the host from which spores 

 were taken for culture, while pages in common type indicate the 

 host on which the culture was successfully established.
