Common beech or sweet chestnut?

The confusion is underfoot in autumn, when both carpet the ground with prickly husks.

The quickest check

The quickest check is the husk. Common beech: about 2.5 cm, woody, with soft prickles. Sweet chestnut: 4 to 6 cm, packed with fine sharp spines. No beech mast on the tree? Check the edge of a leaf.
