Trentepohlia – another “green” alga – can be yellow or orange. You know more about algae than me. I have no clue what this is, either. But it doesn’t look like any lichen I’ve ever heard of… and that does mean at least something. :)

I put this specimen here because may be a lichen, and part algae.
Some algae as Cephaleuros virescens have red parts, red spores similar , but the macro-structure is different. I never seen before this organism.

Here’s my problem with the algae interpretation

Some green algae can get that large (Trebouxia for example can exceed 20 µm)… but they are green! :) Cyanobacteria can be that color, but they are prokaryotes, and typically much smaller (5-10 µm)….. Or at least I think so! There are precious few lichenologists truly expert in the photobiont half of lichens, and I’m certainly not one of them.

The spores have 20 -30 microns diameter , as you see in the new photos, have algae like structures.

What’s the approximate size of those “algae”? Could they be spores or insect eggs, too?

At microscopic view looks a sort of algae
