I add here picture of two sites in Southern Gemany. I already had this in different forums but nobody could help me. As here are specialists of Hypoxylon and related fungi, perhaps somebody knows "who" is responsible for this roundish bouildings which I have already found quite often.

Hi Alfredo,
great :-) - I am happy to have this identification.

Best regards from Lothar
