Grey crustose lichen in the splash zone
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.
One way to tell between Lecanora gangaleoides and the very similar Tephromela atra is to cut the apothecia and look at the colour inside.
Lecanora gangaleoides - dark greenish
Tephromela atra - purplish-brown or purplish-violet
Will have a go next time I go down
