Are you sure it is fungi. Wax will bloom on surfaces and look like a
bluish grey mold. To check if it is just a bloom, use a Q-tip swab
and rub a small spot--only if it is conservation okay--back and
forth.  If it's a wax the bloom will disappear due to heat of
friction, if the color remains on G-tip it is fungal conidia.
