MY experience with the Ultra.edu and foma brand films is that they are both packed in black cassettes, lately ones with the CP-xx and C-41 info under the paper label. Both have very dark edgeprinting with the frame numbers on one edge and the batch number and either "FOMAPAN" , "ULTRA" or just " PAN". The 120 version sometimes says "F PAN" also 400 for the 400 speed film. The BULK FOMA does NOT have edge printing.
MY guess is that someone had some film that got wet or other wise damaged and they sold it loose to cover that up. ALL the FOMA and ULTRA.EDU I have bought form Freestyle came in individual cardboard boxes.
Thread resurrection! I have similar symptoms with 20-year-old 70mm Tech Pan - see my post here and scroll down for the image sample.
Given that I've received some tech pan that has evolved so far that it'd be legally allowed to vote, it would seem to support the notion that the original poster here also has something growing on their film.
In my case I can tell you for sure that it's not double exposures; I made my series of exposure test shots using film loaded directly from a factory-sealed Kodak box. In my case, you can barely see the fungus (?) on the surface of the film outside the image area but it has no silver density there. It's only where fungus AND optical exposure occur together that the effect is visible, as if the fungus is acting as a development catalyst.
The patterns are a little different on mine too.
