Is this fruit edible, please?

They look like conkers to me!

The fruit looks a bit like a lychee but the leaves are quite different. The leaves of a lychee tree are elongated and glossy green.

Thanks for all the helpful suggestions. I'm off out with the dog soon so will pick one and cut it open.

Let us know; if it's a sweet achestnut you could have a good supply for winter.

I don't think they're cobnuts, which are in fact hazelnuts. We have hazel trees in the garden and the squirrel deposits the leftovers all around and buried his winter supply; they have a smooth husk.

ellenvannin my first thought was lychee then I thought no it’s U.K. can’t be

They could be Cob Nuts, very popular here, and very tasty. There are lots of trees in the road my doctors surgery is in and you see people collecting them when they fall.

I thought it was a conker!!!

They look for all the world like Lychees, except for the colour.

Yes, do what EllanVannin suggests. If it’s a walnut, it will be immediately obvious. It doesn’t look like the sweet chestnuts I used to have in my garden - they were spiky enough to need gardening gloves to handle, but they may be a different variety.

Try the plant identifier app you can down load on a smart phone, you just take a picture and it will tell you what the plant is

It looks like it might have a grub or two inside it
Not a walnut or chestnut.
Break one and look at the inside.

Walnut?

If it looks like a chestnut it may well be.
It's hard to tell from the leaves but are they palmate with 5 - 7 leaves?

Horse chestnuts are mildly poisonous to humans.
