Apart from the squirrel-nibbled cone, which is from Nostell, I picked up these seeds and the lichen and the snail shell on a mossy tree-fringed lawn in Ossett.
Some of the sycamore seeds had begun to sprout while all that was left of the lime seed was the pair of wings that propelled it through the air.
The lichen, Xanthoria parietina, would normally be yellow but it turns greenish when it grows in shade. The insides of the spore-producing cups – the apothecia – have kept their colour.
