Collection location: Serra de São Mamede, Portugal [Click for map]

Who: zaca

No specimen available

Notes:
Compare with observation 299946, found at the same habitat.

I don’t know how to choose between Lecidella carpathica and Lecidella stigmatea, taking into account that the specimens lived on the siliceous stones of a fence and that apothecia are flat.
Quoting from the reference below:
“Lecidella stigmatea that grows on less acid rocks and at maturity with less convex apothecia, and less coarsely verrucose thallus”;
“Lecidella carpathica of which the thallus is roughly granulose and apothecia markedly convex, on more acidic rocks”.

Dimensions of the spores:
(12.7) 13.3 – 16.3 (17.5) × (7.3) 7.5 – 8.9 (10.4) µm
Q = (1.4) 1.5 – 2.05 (2.1) ; N = 21
Me = 14.9 × 8.4 µm ; Qe = 1.8
