So, since some of those are chinense, it could be VLS. Then again, it could be an actual virus. If it's VLS there's no point in keeping it as it's going nowhere. If it's a virus, then it presents a greater risk. I can't be sure it's one of the two, but if there's a chance of virus I'd dig it out and toss it along with the small space of dirt around it - being careful to be sanitary with tools and such not to spread the virus if there is one.
