You have Immersaria cupreoatra, the Lecidea atrobrunnea look-alike. Thanks for the reminder.

This is very common for Kazakhstan: together with Immersaria cupreoatra

This is very common for Kazakhstan: most of the photo looks as Immersaria cupreoatra (2 units) and Lecidea atrobrunnea group is along edges (mainly on the left side)
