Observation 113887: Pertusaria heterochroa (Müll. Arg.) Erichsen
When: 2012-10-14
Who: zaca
No herbarium specimen

Notes: Similar to Pertusaria pertusa but with the discs more open than in this species, and in this respect more close to P. pustulata. However, the warts are globose and slightly constricted at the base, contrary to the latter species where they are flat and expanded at the base. The chemistry and the dimension of the spores are more likely P. pustulata than P. pertusa. As in both these species the asci are 2-spored. The average dimensions of the spores are: Me = 115.1 × 35.1 µm ; Qe = 3.3 (N=12), none of which less than 100 µm long. The spores are halonate and the outer wall is slightly ornamented.
