A couple of ideas come to mind.
1) You could use a Dextran-Fluorochrome marker and image the boundary by
negative staining (The agar would be, say, green and the fungus would be
non-fluorescent as black)
2) Use a dye that would have a group that is cleaved making it fluorescent
(I clearly know nothing about fungus except that I like some types on
salad) such as Flou-3-AM but I don't know if the fungus has the
appropriate enzymes or not.
