Arthur: Cultures of Uredineae, 1899-1917 235 



Pages 51, 60, 67, 77, 103, 114, 127, 146, 160, 174, (J.M. 11: 57, 66; 12: 16, 

 26; 14: 14, 25; My. 1: 236, 255; 2: 225, 239), after Puccinia fraxinata, for 

 " Schw.," read Link. 



Page 62, first line of reprint, for " 1," read 12. 



Page 64 (J.M. 12: 13), under no. 6, for "Schw.," read Desmaz. 



Pages 66, 77 (J.M. 12: 15, 26), under no. 7, for specific name " aquat-ilis " 

 and " aquatilis Wahl.," read nebraskensis and nebraskensis Dewey. On page 

 66 the comparison of the large, thick-walled urediniospores (common on this 

 host, the form being known as Puccinia Garrettii Arth.) to the amphispores 

 of P. Caricis-stictae was an error. It may be pointed out here that the same 

 mistake regarding name of the host also occurs in Sydow, Uredineen 21 15, 

 Barth. Fungi Columb. 2351 and 3838. Carex nebraskensis is a very common 

 sedge about Denver and Boulder, Colo., while C. aquatilis is rare or possibly 

 absent. 



Pages 85, 92, 94 (J.M. 13: 195, 202, 204), under Lactuca, for " virosa," 

 read scariola. 



' Pages 93, 95, 107, 114, 130, 146, 195, 201 (J.M. 13: 203, 205; 14: 18, 25; 

 My. 1: 239, 255; 4: 26, 32), under Gymnosporangium, for " Nelsoni Arth.," 

 read juvenescens Kern, and also delete the last sentence under no. 19 on page 

 107 (J.M. 14: 18). Gymnosporangium Nelsoni and G. juvenescens were for 

 a time confused. Both produce aecia on Amelanchier and Sorbus, but the 

 former gives rise to woody galls, often very small, while the latter is foliicol- 

 ous. 



Page 96, first line of the reprint for " 1907," read 1908. 



Pages 100, 180 (J.M. 14: 11; My. 4: 11), under Puccinia, for " montanen- 

 sis Ellis," read Agropyri Ellis & Ev., as pointed out on page 263 (My. 8: 139). 



Pages 109, 115 (J.M. 14: 20, 26), under no. 2, for " Cryptandri Ellis & 

 Barth.," read substerilis Ellis & Ev., and for " Sporobolus cryptandrus (Torr.) 

 A. Gray," read Stipa viridula Trin. 



Pages 112, 115 (J.M. 14: 23, 26), under no. 6, for " mutabilis Ellis & 

 Gall.," read Blasdalei Diet. & Holw., for " reticulatum Fraser," read Brande- 

 gei S. Wats., and for " recurvatum Rydb.," read cernuum Roth. 



Page 123 (My. 1 : 232), under no. 11, for " Aster arenarioides D. C. Eaton," 

 read Erigeron arenarioides A. Gray. 



Pages 129, 130, 146 (My. 1 : 238, 239, 255), the small form of Gymnospor- 

 angium on Juniperus virginiana, which gave rise to pyenia and aecia on Cra- 

 taegus punctata, should have been referred to G. floriforme Thaxter. 



Page 133 (My. 1: 242), delete the entire paragraph beginning "The aecia 

 of this species," etc., except the first sentence. 



Page 147 (My. 1: 256), under no. 8, for " glomerata," read mexicana (L.). 



Page 173 (My. 2: 238), under no. 1, change the reading thus: Teliospores 

 on Carex lanuginosa Michx., sown on Onagra biennis (L.) Scop., and on C. 

 trichocarpa Muhl. sown on Gaura biennis L. 



Pages 178, 180 (My. 4: 9, 11), 19th and 6th line from bottom respectively, 

 for " Douglasii," read spartioides. 



Pages 180, 189, 197, 200, 231 (My. 4: 11, 20, 28, 31; 7: 72), as a 

 species of Senecio, for " lugens " or " lugens A. Gray," read spartioides or 

 spartioides T. & G., respectively.
