The spores are somewhat larger than those of Magnus, being namely 20—25 ^ 12—15 fjt«. In fact, the morphological difference between the two spe- cies is rather great, as well regarding the shape of the spore as the sculpture of the membrane, which has been evident to us by examining specimens of E. cypericola from the classic locality. We found the size of the spores agreeing with the statement of P. Magnus (17—20 ^ 11—IM, wherefrom it thus becomes evi- dent that the spore inE. cypericola is relatively considerably broader than in E. caricicola, the propor- tions between length and breadth being respectively 1,4:1 and 1,7 :1 (flg> 7—8).
