Notes: Similar to the one in observation 163519 with the difference of having a C- reaction, instead of a weak C+ orange, and also a weak KC+ orange reaction. The result of the application of the key in the paper cited there (repeated here for convenience) is the same: Pertusaria heterochroa. It is characterized by having asci with two spores each, the KC+ orange reaction, striated spores and reacts C- in hymenium, in which it differs from P. dispar with hymenium C+ red. In this specimen, the striation of the spores is remarkable in some of them.
A particularity of this specimen is that its thallus is being invaded by Sphinctrina tubiformis, causing the fallen of the verrucas, leaving pits on the thallus. In this respect it is similar to the one in observation 163571.
