The invisible ancient ruins

I was having breakfast when I noticed some strange looking mold on the wood of the table where I was sitting. I was only expecting an amorphous surface when looking at the mold with the scanning electron microscope but those blue crystals on the image appeared … What are those strange crystals on the mold? They seem to be some ancient elven ruins from the micro world we cannot see with our eyes…
