Great to see that you returned to the site for another look at the fungus and to note that it matches our finding ie old warty growths on the script fungus which was growing the branch of a dead tree. Thank you so much for your helpful info, I have learned a lot - I didn't even know that lichen attracted parasitic fungus, a whole new thoroughly daunting area of exploration!

Thanks Brian. I have seen wart fungus on slightly weary looking trees and wondered if they cohabit with the graphis lichen. Let us know if you find anything. It is an interesting spotting anyway !

Thanks for your remarks dearhumi and Leuba. I'm still researching. I went back to the site after discovering the fungus to obtain more information to help find an ID. What I found was that the tree was dead and the fungus seemed somewhat aged. I cut into it with a knife but that didn't reveal much other than it seemed old. According to Wikipedia Graphis scripta is susceptible to parasitic fungus, it mentions 2 of them. This doesn't look like them. It may be that this is a black wart fungus that would be there regardless if the script lichen was there or not (it seems to be covering anything with regards to the dead tree). I'll keep looking into it.

Thank you for posting this - we spotted a similar occurrence in damp deciduous woods (mainly hazel, ash, birch, hawthorn etc) here in Somerset, UK; we have been unable to identify it so will keep checking in the hope someone will ID yours!
