notes

Because the occurrence of the genus Phragmidium on Fragaria is considered doubtful (Termorshuizen & Swertz) or is excluded (Gäumann, Klenke & Scholler, Petrova & Denchev), the pictures above are interesting. Because no telia were available, a definite identification is not possible, but most probably it will concern Ph. fragariae
