Alyxoria varia (formerly Opegrapha varia)
Alyxoria varia (formerly Opegrapha varia) on tag alder (Alnus rugosa) bark. The green algae Trentophila is the photobiont in this lichen association. Although Trentophila is a green alga (contains chlorophyll a and chlorophyll b) it is red in color owing to the pigment carotene.

In the same time according the Mycobank and the Lichenportal the accepted name is Opegrapha varia, Opegraphaceae family
I am not sure which one to create. Posted 4 years ago
When I first identified this lichen after finding it a few years ago I was using Lichens of North America (Brodo, Sharnoff, and Sharnoff) as my primary guide and then checking places like the Lichen Portal which at the time was using Opegrapha varia for this one. Posted 4 years ago
Edit: I just found another place where this name is used but put in a different family: Lecanographaceae

"The genus Alyxoria Ach. was recently reinstated by Ertz and Tehler (2011) based on phylogenetic studies to accommodate the species of Opegrapha varia group characterized by varia-type ascus. Moreover, species of this
group have epruinose to pruinose ascomata with usually exposed hymenial disc, similar to the species of Lecanographa Egea & Torrente. Meanwhile, the family Roccellaceae s. lat. was segregated into four separate families: Lecanographaceae, Opegraphaceae, Roccellographaceae and Roccellaceae s. str. in recently published studies (Ertz and Tehler, 2011; Frisch et al., 2014). Subsequently, the genera and species previously placed in the
family Roccellaceae were also segregated and assigned to different genera, and even transferred to different families of the order Arthoniales. As a result, Alyxoria is transferred to the family Lecanographaceae."
A new record and key to the genus Alyxoria (lichenized Ascomycota) in India. Siljo Joseph, T. A. M. Jagadeesh Ram, G. P. Sinha, V. S. Ramachandran. Feddes Repertorium 2016, 127, 30–33, DOI: 10.1002/fedr.201600005
They cite the primary literature on the current concept of this species which places it in the genus Alyxoria, family Lecanographaceae. Posted 4 years ago

I'm reading another on the Arthoniales (http://lutzonilab.org/publications/lutzoni_file541.pdf) describing changes made based on new molecular data. It will be a couple days before fully digest this. Posted 4 years ago
