Recognized by sight: Bloody comma lichen
This is an odd one in that the “commas” here have grown extraordinarily dense (probably why it is confusing) but the general pattern is still visible, particularly in the helpful magnified pics. Perhaps these are quite old? See my comment here and notes of your linked observation. Cool sighting!

Note that the orange coloration

is from free-living Trentepohlia growing on top of the thallus. The underlying lichen isn’t necessarily orange. This is a common phenomenon with trentepohlioid crusts on the Pacific coast.

Is p. Occidentalis, which is quite different and brownish green in color.

I wonder if this is a Pyrenula sp.

Unfortunately, if it has perithecia (or any reproductive organs whatsoever!) I can’t make them out in these photos. :(
