Did you consider Peridiothelia fuliguncta which has similar spores and occurs on Tilia bark? It is described and illustrated by Hawksworth (1985): "A redisposition of the species referred to the ascomycete genus Microthelia" (Bull. Br. Mus. nat. Hist. (Bot.) 14 (2): 43-181). I can mai you a copy of this paper.

Hi,
Good guess from Eduard, I agree.
I posted photos in Ascofrance database.

PS : it's a fungus that is not exclusively lichenicolous.
I did not consider Peridiothelia fuliguncta, in fact I had no idea of what it was. There is a key and description of it in "Bulletin of the British Museum" 1985 by DAVID L. HAWKSWORTH, it fits very vel.
Still it would be great if you, Eduard, could email the paper you mentioned.
HAWKSWORTH writes: "Probably never lichenized".
Thank you very much for help.
