Update,unidentifiable hairy substance further analyzed.Jimi,took the hairy substance out of trash can (did not flush down drain as stated earlier,put in trash can)took a close look and seemed to contain dark colored hair about 3/4" long and other smaller debris mixed in.thinking back to yesterday remembered dropping one sheet of film on dirty floor and throwing the film in the fixer to use as a clear spacer later on (wast not want not).Also have a dog that is starting to shed winter coat (what a mess she makes to) and even though the door stays closed to darkroom I must have picked up some of her shedding hair on my shoe and deposited it on the floor of the darkroom,after that Murphy took over and put it in my tray via the film I dropped on the floor. That is my most logical conclusion can think of,but still like the mutant contaminant theory.
