Not sure the exact species of this mature walnut tree in our backyard, so if anyone knows, that's appreciated!! But, possibly more concerning, is if it has a fungi outbreak? It was just pruned a few months back, but of course it didn't have leaves yet, and otherwise it seems healthy!
Second to last* photo, shows questionable fungi, and/ or growth on leaves. Thank you for any feedback :)

I don't know your walnut but those little things could be galls.

Yes, they are galls caused by a type of mite.

Does your walnut tree have a graft line? In walnuts, its easy to see - its were the trunk changes a couple feet off the ground.

Are your walnuts easy to get into? It really looks like a black walnut.

English Walnut! Daisy, you've never tried to crack open a black walnut, have you? It requires a hammer on a hard surface, and they aren't loose inside the shell. They need to be picked out, which is why they are sooo expensive to buy. I do agree with some sort of galls on the leaves.

Agree with a leaf gall of some sort - and that those are NOT Black Walnut (Juglans nigra).

I grew up with "pig nose" trees and those thick shells sure looked like them to me. And the meats aren't out of the shell in the photos. But without more answers from Crowmama, we will never know.

Is it possible to get a picture of a whole leaf including all the leaflets? It doesn't look like black walnut and definitely not English walnut (not enough leaflets).

Hello! Thank you for all the replies :)
It was dark by the time I saw this, but just got a few more pics!

Thank you, we will have to see what to do about the galls!

I don't see a graft on the trunk(?)

Another leaf pic,,tried to be sure the sun was hitting it for detail...

And, I cannot open this nut for anything!
The unripe ones squish easily under the pressure of my weight when stepped on, but the one pictured below, is still not open. Will try to use a hammer, or nut cracker, and post the inside lol

Unfortunately, none seem to be anything but green and sticky, or totally dried out like this one, and the one above (which I find on the ground, already halved like that...)

We have me never eaten them, and can see why someone might be detered! They're a very rough nut to crack - seriously Smiling

The animals don't seem to care for them, either...

It appeared to resize my photo, so the whole trunk is not available. Will see if I can edit it from my phone, to change the photo size Smiling

By whole leaf I meant as in this picture, showing all the leaflets including the terminal (end) one if present. You don't need to do anything about the galls they are generally harmless.

When you click on the picture it opens up so you can see the whole thing.

I agree about the galls. You can cut the leaves off if you don't like the look but they won't hurt the tree.

Which picture? I'm looking to see the whole leaf with all leaflets flat. I can't make out if there is a terminal leaflet or not for sure from the pictures or count the leaflets.

I'm currently leaning towards Juglans hindsii (Northern California walnut or Hind's black walnut) athough apparently there are also hybrids.
