Growing on a piece of stone near the sea.
According to the site of AFL (Association Française de Lichénologie) there are two very similar species of Diplotomma – D. hedinii and D. venustum – which differ by the K reaction on medulla, K- in the former and K+ yellow to red by small plaques (dispersed) in the latter. D. hedinii is the current name in Species Fungorum for D. hedinianum , as it appears in AFL.
I performed the K test on the medulla of my specimen with a negative reaction (see the photo attached). For the spores I got the following average dimensions:
Me = 16 × 7.2 um ; Qe = 2.2 (N=26).
