What is "oropogon"

Oropogon is a genus of lichenised ascomycetes in the large family Parmeliaceae. It is a genus of roughly 40 currently accepted species. It was previously included in the family Alectoriaceae, but this group has since been subsumed into the Parmeliaceae.

All members of the genus have a fruticose growth form. The most obvious synapomorphic character which separates Oropogon from the rest of the family is the large brown, muriform, ascospores which occur singly in each ascus.
