Previously I had written under “Based on chemical feature: K+ purple everywhere”, but this is not true and thus I corrected it. In fact, repeating the K test in a zone of the sample where there are no apothecia the reaction was K-. This was what I expected, since I was convinced that already observed this species (see, in particular, observation 106337). I also made the microscopy but I still was not able to find a correct name for it. The spores are polaricular with average dimensions of ~ Me = 12.1 × 5.7 µm ; Qe = 2.2 (N=14) with an isthmus that varies between 1/3 and 1/2 of the length.
