“Oh shoot, was that a fir or a spruce?”…

Needs to be tested, for sure.

One thing is clear – there are more species out here than most previous literature would admit. I don’t have another point of reference so far – the rest of IDd Lepraria are white, some slightly greenish. I believe the tree in question might be a conifer (somebody knock me on the head so I don’t forget to get tree photo in the future – the mistake I keep repeating over and over again :-(

Hate to be negative but…

I don’t think this is blue enough. L. caesiella is supposed to be on pine bark, not deciduous. Okay, or cedar, I guess. Conifers in general? Or is it really acidic bark?

I’m totally with you about Lepraria. Chemistry can help in some cases, but there are exceptions and it is particularly difficult to do the tests correctly on Lepraria. Color is marginally useful in a few cases (L. caesiella, for example, I was told it is one of the few that you can really ID by sight based on the exceptionally blue color and substrate). I’m not really sure I understand what “pseudocorticate” and “hypothallus” and all of that means for this group, yet. The jury is still out pending a lot more observations…

I just don’t know better when it comes to all-sorediate Lepraria or suchlike lichen. I’m guessing the name at this point because the color is somewhat like my other observation 109164 (it seems lighter because I was shining my macro light at it)
