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.*
