Paul, Some time ago I found the site that spelled out problems with FTM called "Warts". Not wanting to copy the name for UFT, but it would have been a good one, I have looked for something like it. I think that your use of the word Fungus would fit the cause. Some types of fungus can be good to eat and others will kill you. I hope that the fungus Genenalogy.com feeds us is still good to eat.
