White specs/filaments

[Keithb22]

Hey everyone, first of all I appreciate whole heartedly the help you have given countless times. Unfortunately I am back and at a loss, I was looking at a couple of my acans and saw some white hard stringy looking things on the frag plug and have no idea what this is. Any help in identifying if it’s something to worry about? I appreciate any help in advance.

The white on the plug looks like some sort of calcified worm tubes.
