* "Fall trees" is too broad: Many trees change color in the fall. This could include deciduous trees like maples, oaks, or even fruit trees.
* "Large green fruit" is vague: Fruit size and color can vary greatly. What's considered "large" to one person might be small to another.
To help identify the tree, we need more information:
* Location: Where are you located (general region, country)?
* Fruit description:
* Shape: Round, oval, elongated?
* Texture: Smooth, bumpy, fuzzy?
* Size: Approximately how big is the fruit?
* Smell: Does the fruit have a distinct smell?
* Tree characteristics:
* Leaf shape: What do the leaves look like?
* Bark: What does the bark look like?
Once you provide more details, I can try to help you identify the tree.
