To be clear, I suspect you’re right

that these are all the same thing. I was just commiserating. This species seems to like to grow nice, juicy, big, and apparently entirely sterile, thalli. I’m always left wondering: are they really the same as the fertile things on the same rock? But how will we ever know short of sequencing the damned things! At most you can expect to get a weak K+ yellowish reaction. Really doesn’t tell you much. Lots of things are K+y! And K- doesn’t rule it out.

I imagine so.

Being on the same pillar, color & a proportionately tiled surface I was assuming they were the same..
I see your point though; without chemical tests it may be a reach to make that assumption.
I will narrow this obs down to those 3 photos and either follow-up with tests or with matured photos of the same specimens before I include those others.
Thanks Jason.

Certainly the last three photos are L. tessellata

Or closely related. Those sterile specimens are harder to be confident of, aren’t they?
