I have a lot of old yew tress in my garden; underneath one of them is a spread of about 100 of these. They are hard and a bit bendy but brittle and slightly transparent. Some kind of seed case? Or from an insect maybe?
The trees are home to a lot of wildlife, and so is the grass beneath them. Each disc is a cluster of a few stuck together (included 5p for scale!). Anyone have any ideas please?
