the Genus Urophlyctis. 
I have never observed the formation of other propagative 
organs, especially the development of zoosporangia, although 
I have often directed my attention to this point. The forma- 
tion of zoosporangia seems to be wanting here, as in the case 
of Schroeter’s U. major , or it may, perhaps, be restricted to 
the germination of the oospores. 
Urophlyctis Kriegeriana is very common on Carum Carvi 
throughout Europe. Besides Saxony and Bohemia, the only 
habitats known to me up to 1888, it has since been found in 
Thuringia by F. Thomas 1 , and Herr E. Ule has discovered it 
near Coburg, according to a specimen communicated to me. 
G. de Niessl has collected it near Schwarzkirchen in Moravia, 
and distributed it under the name of Protomyces macrosporus , 
Ung., in Rabenhorst’s Fungi Europaei, No. 1100. Herr 
Friederich Stolz gathered it in the Gschnitz valley and in 
the Stubai valley, Tyrol ; and Blytt has found it in Norway 2 . 
I am able, however, to record its occurrence not only on 
Carum Carvi , but also on Pimpinella Saxifraga. The Fungus 
which W. Voss has indicated on Pimpinella Saxifraga as 
Synchytrium aureum , Schroet., in the first part of his Myco- 
logia Carniolica (in ‘Mittheilungen des Musealvereins fur 
Krain,’ 1889), p. 17, is my Urophlyctis Kriegeriana , as I have 
proved by a specimen communicated to me by Herr W. 
Voss himself. Perhaps the parasite also occurs on other 
Umbellifers 3 . 
Another species of Urophlyctis I knew to be the cause of 
a serious disease of the Beetroot in Algiers. L. Trabut 
reported 4 on a disease observed on the thick primary roots 
of Beta vulgaris , var. rap ace 0, at Rouiba, near Algiers. It 
consists of thick fleshy botryoid swellings contracted at the

3 In a collection of Fungi made by J. Bornmuller in Persia, 1892-93, and sent 
to me for investigation, I found Urophlyctis Kriegeriana on Carum persicum, 
Boiss. from the province Kerman, on Mount Kuh-tagh-Ali, near the city of 
Kerman, 2,100 m. above the sea. (No. 4402 of J. Bornmuller, Iter Persico- 
turcicum, 1892-93.)
