Spotting

Description:

i'm not sure, what it is. But i think i have seen it before, i will try to recover the references and give it a real id. ---The big thing, was a mushroom, there's no doubt, but what i noticed,primary, was the little crusty-bubbles on it. They are unregular curved, and hollow, some are cracked open, and the intresting thing is, the walls are pored from the inside.

Habitat:

the big mushroom beneath the weird things, are almost unrecognizable, but next to it was another specimen, which reminded me at a "bitter bracket" (genus: postia / synomyms---> tyromyces/oligoporus/spongiporus) .

Notes:

i have a suspect, but will not mention it, because it is to vague. i will not give a wrong picture !!
