These white sacs have just appeared at the base of an oak tree. There are at least 100 of them. Are they a egg sac or a symptom of tree/root rot? They feel rubbery.

Hi @cathygree

They appear to be some kind of puffball fungus, but they are not a species that I'm familiar with. What part of the world is your tree in? Knowing the geographical location will help to determine what the fungus is. Also, do you know what kind of oak it is, for example English Oak, White Oak, Red Oak...

If the fungus has developed a different shape or changed color over the last week, please post an updated photo. Thank you!

I believe it is a white oak and I live in Nashville, Tennessee. Thanks for the info.

I still don't know what they are! I hope someone else will recognize them.

I did a quick Internet search on "white oak fungus Tennessee", and rubbery white sacs do not appear to be a manifestation of any common oak fungal diseases in your area. As long as the tree's leaves are still green, and there is nothing oozing out of the trunk, I would not panic.
