This fungus occurred in great abundance especially in the neigh- 

 bourhood of Copenhagen in 1894 and 1895, it almost disappeared in 

 1896 (see R 97 i), but reappeared abundantly in 1897. The damage 

 caused by its attacks in 1895 was estimated at VI2 million Kroner only 

 in the neighbourhood of Copenhagen (see K. H. 98 '"'^ R 97 j). Later 

 on it has, however, been doubted whether it was this fungus which 

 caused the disease or if it was only of secondary importance (see 

 F. K. R. 09^*1 £. M. L. M. July 11). 



It has been found in association with a supposed corresponding 

 conidial fructification of the formgenus of Septoria. It deserves to be 

 noticed that it has never been found on Triticum in this country.
