This specimen has a distinctive appearance, due to the thallus coloration and to the pruinosity of the lirellas.
This fact is used was the British Flora in the notes to the description: “Recognized by the yellow-green-olive, waxy thallus and flat, but raised, apothecia with clear, white, powdery margins”. It seems to me that, if this is the standard appearance, there is no problem to take it for another species.
Unfortunately, most of the spores were old and shrivelled. Here are some data from microscopy:
Hymenium tall: ~105 um
(22.6) 24.2 – 28.3 (29) x (6) 6.3 – 7.9 (8) µm
Q = (3.3) 3.32 – 4.1 (4.6) ; N = 24
Me = 26.4 × 7.1 µm ; Qe = 3.8
Spores septation: 5, some with less.
All the data are also in accordance with Ref. 2.
