vii] USTILAGINALES 195 



brand-spores, basidia and basidiospores appear, but no conjugation could be 

 observed. T. primulicola thus resembles the Uredinales in having two 



parasitic generations, the one with uninucleate, the other with binucleate 

 cells. Its hibernating, uninucleate mycelium also recalls the parasitic 

 mycelium of Ustilago Afaydis, or of U. Vaillantii, which consists of uni- 

 nucleate cells.
