1481. Puccinia apii Desmazieres, Sydow 04 ^°^ Liro 02 '^ Selleri- 

 rust (R02a"^ Lind 11a). 



This species is generally stated to be an Aut-eu- puccinia, all authors, 

 however, refer only to Plowright (89 ^^^) who has not tried to culti- 

 vate this fungus, but has only found it on the same host. Juel (99) 

 has examined the cluster-cups finding them to belong to the same 

 type as the numerous other aecidia on Umbelliferae related to Uro- 

 myces scirpi. Further Liro has found (02 °*) that st. II 6. Ill are most 

 like the type of Puce, bullata. 



It is curious that this rust which, according to Rostrup's statements 

 (88 a ^''), was so common in 1887 that all leaves of Aprium brought 

 to the market were red and dusty, should now have quite disappeared 

 from the country; I have often looked for it without finding it, Kle- 

 bahn also states (10) that he has been unable to find it near Ham- 

 burg; Liro (02) mentions it to have been found in Sweden in the 

 years 1866—1885, but not later; in Switzerland it seems not to have 

 been found since the years 1878 and 1883 (Fischer 04 "'). Without 

 doubt it is due to the fact that the horticulturists now grow celery 

 of a higher power of resistance.

 kilde C/n 90 Wendt), Basnaes a Snedinge (P. N. 24/io 74-5/9 79); Amager

1482. Puccinia conii (Strauss) Fuckel, Sydow 04 "^^ Liro 02 »" 

 Brachypuccinia, st. II an the leaves, petioles and fruits June— July, 



St. Ill on the leaves and stems during the rest of the season. 



Liro mentions (02 ^') that Johanson has found fruits of Conium 

 (at Tiselholt Septb. 7. 82) which were quite filled inside with Uredo 

 just as if they were attacked by smut. 



Conium maculatum. J. Thornlng!, Viborg!; Fsene; F. 0. Aby (™/e 70 see 

 Lagh. 95), Tiselholt (Johanson), Skaarup; Thorseng Valdemarslot; Lang. Rud- 

 kebing; S. Kebenhavn, 0rsl0v (P. N.), Vordingborg (Thomsen); L. Krage- 

 vigshuse. 



1483. Puccinia cicutae Lasch, Sydow 04 ^^^ Liro 02. 

 Aut-eu-puccinia, st. I June— July, st. II July— Aug., st. Ill Aug.— 



October. 



It is a curious fact that this species is mentioned by all more ancient 

 authors even from Lasch 1845 till Liro, in 1902 as a Hemipuccinia; 

 St. I is probably not so common in other countries as in Denmark, 

 but at any rate I have found this st. rather often and always in com- 

 pany with st. II (see Lind 04). Rostrup had already found it in 1884. 



Cicuta virosa. J. Non Melle! (Exs. Vgr. &. Sydow), Ved Se (Gad), Fladbro 

 (Exc. 22/7 04), Varde (Raunkiaer); E. Ringe!: S. Gammelmosen C^/e 84 st. 1 &.
