What tree is this? Thought a chestnut-look like conkers but nut inside is tiny, take it they're not edible

We thought that two massive trees at the bottom of our new garden were chestnut trees, now I'm not sure.





They look a little like conkers, but the case is much pricklier and the inside 'nuts' are tiny.





Definitely not horse-chestnuts, the nuts are much smaller.





The case is a bright green spike when on the tree.





Could anyone shed any light on this one, I'd really appreciate it !





Many thanks

If the "nuts" are small and flat and you get about 4 or 5 of them in each shell, it's a beech tree. The nuts aren't poisonous, but they are nearly all skin so there's nothing to eat. People used to chew them before chewing gum became popular.
Reply:Sounds like a sweat chestnut and they are edible
Reply:Sounds like a sweet chestnut but don't go eating them until you are sure. Take some to your local garden center and they will advise you - take a small twig with leaves on as well if you can.
Reply:The bark on a sweet chestnut tree is very distinctive, it twists around the tree and almost looks like lattice work. The tree goes very 'lumpy' when it gets old and the lattice work is not noticeable anymore.





This link will show you the bark.

The nut case is bright green and has lots of hairy type spikes.


Another link for you to compare with what you have in your garden.

Reply:C'mon you tree experts. It could well be a tree in the maple family, by a description of the fruit...
Reply:Sounds like the Spanish Chestnut...or Castanea Sativa





nuts are edible...wood used for building as opposed to Horse Chestnut which has non edible nuts and wood no good for anything..
Reply:Are they sweet chestnut trees? If that is the case they can be roasted and eaten. Use the net to identify it using leaf shape and the nuts. Or are they beech nut trees?
