Identification: Is this a moss?

We were paddling up in Indian Arm and saw this very bright moss-like plant hanging on cliff face. North-eastern facing. High above the tideline.

Almost neon green….

Any guesses as to what it could be? Thanks!

 

Are you referring to the yellow-green lichen below the angled rock fracture?

 

Good morning and welcome to the forum. I agree with vitog that this is lichen and not moss.

Agree with lichen, and Chrysothrix would be likely given the habitat

 

Oh wow! Thanks for that. How did you know it was a lichen? Based on what features?
Thanks!

 

That’s right!

 

Thanks for asking @KitsMoss

Combination of;
- bryophytes that are that thin & grow on rock are usually more green and in seeps vs shelter under overhang
- yellow & thin on rock is more often lichen in general
- in this region, large areas of rock covered by thin layer of yellow usually turn out to be Chrysothrix when you look up close.
- relatively Undisturbed non urban environment
- vertical rock face, and not in intertidal ocean spray zone
- continuous layer of yellow, no variety of shapes or patterns
