Hello.A tiny ascomycete, appearing as erupting gra
Conidiomata on leaves of Lysimachia vulgaris.

On the discoloured leaf lesions of Lysimachia vulgaris, caused by Septoria lysimachiae, I found several separately growing synnemata (white stem with a round droplet with secreted conidia at the top).
The fascicle has the following dimensions: height 410 µm, width base 175 µm, width top 93 µm
The conidiogenous cells are filamentous and have several branches. On them develop conidia, fusiform and in lateral view slightly allantoid: dimensions:
(5.2) 5.8 - 6.6 (6.9) × (1.5) 1.9 - 2.3 (2.4) µm; Me = 6.2 × 2.1 µm ; Qe = 3
Is there any connection with Septoria lysimachiae or is this an anamorphic form of another species. Any help is welcome as I am not coming to an identification.
Kind regards,
François
