Common Orange Lichen

lichen

Alongside a track through fields of seedling oilseed rape there’s a stretch of hedge where many of the branches are encrusted with this yellow foliose (leaflike) lichen, Xanthoria parietina, sometimes called common orange lichen. It will grow on twigs, branches and stonework, even on painted surfaces, especially where extra nutrients are available – for instance from bird droppings. In this case the extra nutrients might come from overspray from the field and to a smaller extent perhaps from the exhaust from the occasional passing vehicle on this quiet country lane.

Sycamore Seeds

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.
