I am still toying around with the image stacks from the Agonimia vouauxii #lichen. Rocking stereo with Zerene stacker - still some issues with the processing.

Springerle are the true lembas.

I have played around a little bit with cross eye stereo on high magnification macros taken from the A. vouauxii. In this case it adds both to my understanding the geometry of the lichen and my puzzlement - what are those white structures. I suspected some lint, but they seem fungal.

Baeomyces rufus (I think) #lichen from a wayside embankment in the forest. On loamy material over siliceous rock.
I will need to sit down with this for an evening to be sure though as I have no first hand experience with this species.
The short stalks of the apothecia to not show from this angle.

Less fancy than fencepost-top Cladonia is this fencepost Trapeliopsis (I think, likely T. flexuosa). I wonder if the apothecia belong to the #lichen or if some other ascomycete is sneaking in from below.

My #lichen excursion from yesterday did not yield many eye catching photos - I went to a small creek and looked for freshwater associated lichens. Mostly verrucaria and maybe something-something trapelia.
Boring brown and grey crusts that probably do not excite many people.

Es fühlt sich an als ob ich in ein Gebiet eindringe in dem Krajas @krajamine.bsky.social Geister wohnen.
Ich bin besser vorsichtig um die nicht zu stören.

I am still working on my #lichen with white apothecia. Tobys suggestion Bacidina matches and I got some ideas, however I have not yet arrived at a firm conclusion. If it is a B then maybe a pale morph. I could not find any pigmented apothecia in the sample.
However I got some new photos.

Cladonia #lichen on moss. Wonder what this is, they are a bit more granular than I would like for C. fimbriata and the base seems to have some squamules.

While looking at the moss sample with the Bacidina(?) #lichen I found some structures I thought were pycnidia. The are not. Turns out they are perithecia of another lichen.
With 2 muriform spores per ascus I think this is Agonimia, with small ap. and granulose thallus probably A. vouauxii (I think)

Vezdaea sp. (I think) #lichen under a Peltigera (rufescens, I think). Today on the proper #macrophotography setup (Olympus UPlanFL10x+Raynox DCR150).
