Vouauxiella lichenicola (Linds.) Petr. & Syd.
Parasitic fungus of Lecanora sp.
On apothecia discs of Lecanora sp. and notably on those of Lecanora chlarotera; appear as black dots corresponding to pycnidia, 50-150 µm diam., mainly towards the margins. Conidia ordered in sequence, smooth to minutely rough, 6-9 x 3-4 µm. N.B. Other close species exist but they are much rarer and their identification requires microscopic obervations.*
