Remote sensing of lichens with drones for detecting dinosaur bones
Brian Pickles and colleagues show that exposed dinosaur bones can be remote sensed
with drones by virtue of colored lichens growing on them.

I wasn't sure what I was going to get with this lumpy lecidioid thing (mica schist at ~800m VC96). I was half expecting a mutant Rhizo, but microscopy said otherwise....

Based on morphology and molecular data, sixteen new species are described as part of a study on the taxonomy of Protoblastenia in Finland.

UTTERLY SURREAL LOW ANGLE GLACIER SLIDE!! 😮😱

There are 110 other posts in the vicinity and I took a closer look at about 40 of them. The original one I noticed still happened to be the best in my opinion, in terms of "terrain" and diversity.

In this paper, we show that photobiont diversity increases as lichens age. Interestingly, as the thallus grows, autosporine algae become more prevalent at the expense of zoosporine algae, likely because the latter play a key role in lichen establishment. 1url.cz/@Proto

Orphniospora moriopsis on gneissose granite, Strath Vaich. I think this thing is pretty underrecorded on account of it being a fairly mysterious black crust, but when it's mature it develops a distinct orange pruina which can help to tell it apart from other things

Some super lichens here in the Dolomites. A favourite of the trip so far is Bellemerea alpina, a species that's incredibly scarce in the Cairngorms but in the heart of its range here.

En route to the First Symposium of Alpine Lichenology. Very excited for this! I'll be discussing work from our Scottish hills and looking forward to putting it in the context of mountain environments on a wider scale.

Interesting looking study on the effects of seabird droppings on plant communities. Not read properly yet, but a quick skim and lichens are only mentioned once, despite being the only 'plant' visible in the lead photo (yes I know they're not plants, but)
