Graphoid lichens

@miked @dejayM @JoC
How I miss Nigel - he pointed me to this years ago - and now I’m trying to find a way to present my Lirellate lichens with some meaningful names,this BLS article is really interesting and I can see some things that have puzzled me in my pics

The Graphidion

The Graphidion | The British Lichen Society.

Any suggestions would be most welcome
I’ve attached the tag myLirellae for the moment
Adding this - food for thought?
