The spores of this species may preserve their germinating power 

 for three years; K. Hansen kept seeds of Panicum in a dry place for 

 such a period and then they produced smutted plants when they 

 were sown (see R 99 c^^^).

The mycelium of this species is perennial in the host-plant and 

 prevents it from flowering. The forms on Triticum and Calamagrostis 

 are possibly to be considered as two distinct species (see Plowright 

 in Card. Chron. XIII 1893 "^5).

The mycelium is perennial in the host-plant, Jakob E. Lange has stated

 years, without infecting other species of Scilla growing close by (see R 

 92 g 66), April.
