Answer: Unfortunatley, based on your description I am not able to identify the hairy roots with certainty. It is possible that some sort of unusual fungus is growing through the soil, but I suspect that a neighboring tree with invasive roots has sent some as far as your flower bed. (Tree roots can extend well beyond the overhanging tree branches.) Off hand I don't know of any reason why soil from near a barn would cause a problem such as this, however a well improved and nicely loosened area of soil is very attractive to those roaming tree roots. You might want to consult with your county extension (624-8650) and see if they have any suggestions as to what it is. I'm sorry I can't be more helpful.
