I'm not exactly sure how the 6x7 pentaprism is constructed, but if
there's some kind of corrector glued to the bottom the way lens elements
are sometimes glued together, it might be something that's got into the
glue.
"Bugs" don't eat glass, but they will eat glue.

It looks a little symmetrical to me because it is right where the top
edge of the prism is. When looked at closely, it appears like little
trails left behind by a burrowing insect, but of course insects do not
burrow in glass (that I know of).

Fungus looks more symmetrical. That looks like lint to me. Too much sense
of depth to the smaller piece.
Assuming that it is lint ...
Check the focusing screen. If that's not it then remove the focusing screen
and try a light poof of air to blow it out.
