Standing, dead, this things goes meters up the trunk.Only on one side of the tree.
Could be Peniophora incarnata, ref.: (http://agrozoo.net/jsp/Galery_one_image ... 610a6190e5), but I kind of doubt.

This looks "fluffy". I think these are algae, Trentepohliaceae, e.g. Trentepohlia aurea (but there are more species looking like that).

Nope, does not look like Trentepohlia aurea, it is flat, not fluffy (thread like) like Trentepohlia aurea.

I do see how you could see that. It is not there.

Maybe a "non-fluffy" Trentepohliaceae, I still opt for algae

What bothers me the most is the white stuff, sometimes looks like aerolate lichen (but seem unlikely due to huge surface) here it looks like orange stuff originate from white: https://postimg.cc/wtMHr683
