already found by Troyel (1791), in roots of Brassica or fruits of 

 Cucurbita. In the thin branches of Daucus sclerotia may sometimes 

 be produced in abundance; Rostrup states that some kilogrammes 

 were once brought to him of a size like that of the fruits of the Dau- 

 cus and set free from the stalks merely by the thrashing of the Daucus.

 Heracleum, Daucus, Carum (R 92 b), Phaceolus (R 89 j '"^ 92 j " c. icon, a

Rostrup has made a 

 very close study of this 

 fungus and contributed 

 much to its biology. He 

 first found it in 1869 

 near Skaarup and men- 

 tioned it (71 ") as Pe- 

 ziza ciborioides, a name 

 which Fries in S. M. 

 II ■'■'^ has applied to a 

 similar species which is, 

 however, stated to be 

 found "ad culmos". Du- 

 ring the years 1885-1890 

 Rostrup made a great 

 many experiments in 

 cultivation in the field 

 with this fungus which
