Sydows Statement that Puccinia dovrensis Blytt has smooth 

 spores must be corrected as follows: the spores are furnished with 

 small, dense warts, which, however, will only become visible by an

 and Caeoma cernnae on Saxifraga cernua, which both are described 

 and delineated. J. Lind (Copenhagen).
