Lichen

lichen tendrils

This is a ground-growing lichen I spotted while we were out having a picnic today. I’m not someone who knows much about lichens, so I can’t tell you which exact one this is, but the rooty-looking things are rhizines, used to anchor the lichen (I assume it had been disturbed from its usual position). I think that the bulbous tan-coloured things at the tips of the lobes are apothecia, fruiting bodies. Beautiful, aren’t they?

It’s amazing how different the greens of different kinds of lichen can be.

Two-toned

An oddity—there usually isn’t this kind of colour differentiation between concretions and the surrounding sandstone. The orangish lichens give it a very idiosyncratic look.

Snow on stumps

The first snow of the season arrived last night—not very much, but with enough of a storm to knock out our power for five and a half hours—and then the sun poked its head through this afternoon, so I went out and took some pictures.

These little British soldier lichens look like a hopeless lot of recruits that got lost on maneuvers. Perhaps the sergeant is considering teaching them to build a snow cave.

A few days ago I found a lovely little lichen garden on a fallen tree. Here are some shots from it. I was fascinated by the textural patterning and how it all fitted together, and the subtlety of the colours.

Since I’m on a lichen roll….

This is somewhat related to my last post, in that there’s British Soldier lichen (Cladonia cristatella) in both of them, but it was taken at a different location. I like these little guys, so stiff and solemn in their uniforms, nodding towards each other so formally.

Tiny black lichen

Aren’t these cool? I’m not even sure how I spotted them, as they were pretty small. It’s some kind of little black lichen growing on a rock; I’m not anywhere near my field guides at the moment, so I haven’t a clue what it is. What I thought was interesting was the way it’s growing in concentric circles.

And it showed up on a truly gorgeous rock, just covered in a lichen-y rainbow of colours.

Looks like sea urchins have been grazing here....
