Interesting that you comment about the fine network of black lines. I see that parasite on L. argopholis all the time, too. But I’ve never found it fertile, so I have no idea what it is.

Jason, thank You very much for your useful comment!

You are right with L. argopholis. I visited this point again. Apothecia became darker. Most of talloms have tall areoles with a net of black microveinlets (handlens). One tallom has been eaten by other lichen completely (?).

One possibility is a xanthone-deficient Lecanora argopholis

Its areoles can become quite verrucose and tall. And it’s not uncommon for it to be “albino” like this. I’ve seen white and yellow thalli growing right on top of each other. The vertical habitus is a common response to growing in unusually shaded locations, for example.

What Lecanora has such a shape as lots of individual cylinders ?

What Lecanora has such a shape as lots of individual cylinders and their clusters?
Only this kind is looked like a mottled soft moss

I don’t think Koerberiella wimeriana apothecia ever get so big

Don’t they remain immersed? Also, Koerberiella tends to occur in streams. I think Lecanora is a safer bet.
