Now this is what it’s supposed to look like!

I’ve talked to experts about this species while in the field. I see a bewildering range of leprose greenish crusts with varying amounts of fibrous prothallus. Even though all have usnic acid, the color varies dramatically from almost yellow to bluish-green. You’ve shown me incredibly scanty thalli, presumably just old and dying?, and well-developed things like this, confusing the issue even more. No one’s been able to convince me that all of this material is the same thing. I just don’t know what to think about it yet.

But these specimens, I think all will agree, are clearly proper L. thysanophora.
