Yellow foliose lichen in patches on tree. Present slighlty more abundantly on roadside at base. Spaced sparsely on pavement side (north side).
Consistent grey fruticose lichen all over tree.
Absence of lichen on bottom foot of the tree on pavement side.
Canopy was quite open, tree had rough bark. Was quite small and thin.
Similar occurrence on another tree up the road of the same species and shape.

Some fungi are very poisonous so a mistaken ID could have serious consequences.

Not fruticose

The yellow foliose lichen is Xanthoria parietina, the small grey one is either Physcia tenella or P. adscendens - foliose rather than fruticose.

I think more likely P. adscendens, but without clear, close-up photographs, who can tell?
