I see potentially five species in the first photo: 1) the pruinose broad-lobed yellowish thing that these observations are focused on, 2) small orange thing (Xanthoria s. lato. for sure), 3) small-lobed epruinose yellow thing (Candelaria?), 4) broad-lobes pale gray thing (no hint of yellow in that, probably Parmeliaceae), 5) the greenish crust behind the subject specimen (no clue, but pobably a lichen).
