oblongisporium Fuck, censu Rostrup (94 f ''^) non Klebahn (05 ^*').

On the 29. May 1889 Rostrup found the young plants of Pinus 

 montana &. silvestris in the Arresedal nursery to be severely attacked 

 by Peridermium acicola, and the severity of the attack was propor- 

 tional to the distance of the plants from a group of Campanula rapun- 

 culoides infected by Coleosporium (R 94 f ^'). 



Klebahn classifies the species into several special forms which are, 

 however, not definitely separated from each others. It is seldom sought 

 in vain on the more common species of Campanula. 



Campanula rapunculoides. Common. Campanula trachelium. F. Glue Mose ! ; 

 S. Lyngby (F. K. R.), Boserup (Thomsen), Skelskar!; L. Stensgaard (Aug. 62); 

 Falst. Stubbekebing. Campanula latifolia. J. Dvergetved (V. S.), Nerlunde 

 (Jeppesen); F. Tiselholt; L. Stensgaard, Sallested; Falst. Sortso. Campanula 

 rotundifolia common. Campanula rapunculus. L. Saebyholm. Campanula lych- 

 nitis. S. Landbohejskolens Have. Campanula persicifolia. S. Rervig; Meens 

 Klint!. Phyteuma spicatum. J. Sadal by Viborg!; F. Klingstrup. Lobelia cardi- 

 nalis (hosp. nov.). S. Ordrup (i^/g 1910 G. N. Brandt). 



Vestergren has found Coleosporium on the neighbouring Lobelia fulgens 

 atropurpurea near Upsala, and proposed the name of Coleosporium camp. f. 

 lobeliae (Vgr. 99 "B). 



1351. Coleosporium petasitis (de C.) Lev., Peridermium Boudieri 

 Fischer. 



Petasites officinalis noticed from J. Viborg Sa (^/a 74 and again 2/9O8I); 

 F. Glorup; S. Taarbaek (A. B. 2^/9 1870); Falst. Stubbekebing. Petasites spurius. 

 Falst. Tromnaes by Bete Nor (R 99 a ^eo a 99 b). 



1352. Coleosporium tussilaginis (Pers.) Lev., Syn: Uredo tussi- 

 laginis Pers. Syn. "^, Schum. no 1547, Peridermium Plowrightii Kleb., 

 Hestehovens Brandstev (H. 37 ^°^). 



Tussilago farfarus very common. 



1353. Coleosporium senecionis (Pers.) Lev., Syn: Uredo sene- 

 cionis Pers., Syn. "^, Schum. no 1545, Caeoma cinerariae Rostrup 

 (97 m ''^), Peridermium oblongisporium Fuck, censu Klebahn 05 '°^, 

 Perid. Wolffii Rostrup partim (89 b ^=''), Stolt Henriks Brandstev (H. 

 37'°^), Lit: R 94^*^6. 02 a 321 



Rostrup himself says (97 m ''^) that he doubts whether the small 

 groups of spores of Caeoma cinerariae are really caeoma or uredo, so 

 I felt (Lind 07 b) obliged to use this name as a synonym under this 

 species. 



According to the investigations of Klebahn st. I is found on Piiius 

 austriaca, montana &. silvestris; st. II &. Ill are often found in abun- 

 dance on leaves and stalks of the common species of Senecio when
