Observation 105276: Pertusaria pustulata (Ach.) Duby
When: 2012-08-06
Who: zaca
No herbarium specimen

Notes: Another grateful surprise. At the place of the observation I thought it could be another Graphidaceae, maybe a sugestion since I observed dozens that day. Only when I look at the photos I recognize that it may be a Pertusaria. Then I reccal the discussion concerning observation 68661 and conclude that probably was P. pustulata. The macroscopic characters, that Jason mentioned in MO observations of this species, fit very well and the microscopy is in favour of this classification, revealing 2 spores/ascus with average dimension of Me = 79.7 × 31.1 µm ; Qe = 2.6 (N=20); Moreover, the spores are relatively smooth and, so to say, only faintly ornament, as British Flora describe them.
