Fruticose lichen (and grey crustose lichen)
Caution: Do NOT use iSpot to identify fungi to eat!
Some fungi are very poisonous so a mistaken ID could have serious consequences.
No interactions present.
I see no fruticose lichen here, only poorly developed crustose species.
There are at least two moss species and some grass, the clumped moss species apparently being Orthotrichum anomalum.
Thanks Alan - I wondered about this one. I think I need to revisit my knowledge of fruticose lichen - wishful thinking perhaps, given the poor pickings in the necropolis!
