We’re using the exact same information! I hope we’re right. :)
- “Lecanora albella is readily distinguished by its heavily pruinose apothecial disc, relatively small apothecia with thin margins, and the presence of protocetraric acid”.
- Chemically, the two species [L. albella and L. caesiorubella_] are indistinguishable, but L. caesiorubella generally has larger apothecia and a thicker pseudocortex.
So, my proposal of classification was based on the following: My specimen satisfy the conditions of the first item above and the apothecia are very smal with thin and not flexous margins. Therefore, I chose L. albella.
Let me add that this specimen did not react K+y to r and it remains on K+y. But, this was mentioned in CNALH to be possible for the chemical reactions.
(I, too, concluded mine was L. albella based on apothecia mostly < 1 mm (only one as large as 1.5 mm) and thin rims with cortex ~50 μm. But in my case, in the Santa Monica Mountains of southern California, only L. caesiorubella_ has been reported and is far more common in the general area, making me second-guess myself. I had to double check the chemistry to verify KC+ rose – most noticeable on the apothecia if I was quick to apply the C before the K+ yellow turns to red.)
