Serendipity is a curious thing.
On two separate twigs of two different trees, the same two species of lichens grew side-by-side. Happenstance is that I found both twigs within a few minutes time, close enough together that the circumstance of collocation was not lost upon me. So, I present the two twigs together despite it being against usual protocol of observation management.
Submitted for your consideration,
Pertusaria (species as yet unknown to me) on the left,
and Ochrolechia africana on the right.

An unusual individual with numerous shallow lobes on the leaflets.
I found this individual 3 years ago.
Happily, it has grown considerably since.
