Fungal contamination of Southern bot

I was shown an autoradiograph of a southern blot with a strange result.  There 
were a few  dark blobs on the film. These blobs looked like ungly snow flakes.  
There was a central dark image on the film with radiating tentacles.  These 
tentacles had tentacles of their own.  I was told this was fungal contamination.

I have never seen this before.  Is what I described consistant with fungal 
contamination?  How does one fix or prevent this from occuring again?
Thank you.
