 on Rliainnus catliartica L. separated the present species from the old Puc- 

 cinia coronata Cda., under tlie name of Puccinia coronifcra (2). But 

 Nielsen (i) in 1S75 had already found a similar relation existing between 

 the .^cidium on RJianinus catliartica and the coronate Puccinia on Lolinin 

 perenne and he gave it the name oi Puccinia Lolii, which should be adopted 

 on account of its priority. 



Eriksson and Kleb.\HN recorded six specialized forms to this species, 

 and among them y. sp. Avcncu only has been foimd in our country. Ihe 

 uredospore-stage is common in our country, but the teleutosporc-stage seldom 

 occurs. Last fall I found the telcutostagc on oats in the vicinity of Sapporo,
