Q.These Roots Have Appeared In Our Garden For The First Time In 20 Years. Any Idea What They Are?
Is this plant evasive and should we be pulling up the roots?

They look sort of like roots, but I wouldn't expect to see them growing above ground. I'm wondering if they are fungi, types of mushrooms. There are all sorts of strange shapes that go with the fungi, and they usually pose no harm to its surroundings if you want to leave them. There could be harm if someone or a pet ate them, so if that is possible, I would pick them up with a gloved hand and discard in trash.
