Re : asco on stone
Hallo,
it could be a member of Verrucariaceae like Thelidium minutulum Körb., which is a typical pioneer on small stones

Re : asco on stone
Hello Dragiša,
I don`t have a determination for you.
But I think the orange color is because of Trentepohlia green algae becoming free because the "cultivating" lichen fungus is dying.
Best, Lothar

Re : asco on stone
I guess no trentepohlioid algae are present in the last microphoto, and the brick colour on th fiirst picture is that of the stone, is it a weathered piece of brick? or of roof tile? or is it a volcanic or metamorphic pebble rich in iron oxides?

Re : asco on stone
Thanks, that's right, I didn't even look at Verrucariales.

Re : asco on stone
It's a piece of brick, not a stone, I see now.
