Next to falls, very humid constantly.

I mean Daucus carota (queen anne’s lace) has a colorless, tiny root. Our carrot is a very specialized cultivated form. Why is it orange? Because humans think it looks cool! (Or tastes better, or someone figured out it is more nutritious, or…)
Wikipedia says it helps with photosynthesis in a couple of ways, too technical for me to understand at this hour, but somehow associated with excess light, I think.
how the amount of the algal pigment would be in relation to the thickness or other pigments in the lichen… could take trees with the same general amount of lux or whatnot, that have different lichen species with trentepohlia in them, and then somehow measure the amount of carotene pigment in those thalli to get an understanding of the different kinds/quality of shields in different lichen species…
I wonder why carrots bother having carotene anyways? Being underground an all. But this is a fungi forum…
Remember all that stuff you were telling me about altering the frequency of heterocysts and stuff in the lichenized state? No reason a priori to expect the same abundance of the carotenoid pigments inside the lichen, either. Could be a response to photo stress (carotene is a sunscreen, isn’t it?), therefore would actually expect it to have less orange pigment under the protective cortex of a lichen thallus.
Your guess is better than mine. I can´t even scratch my head on any of these crusts without a scope…
Trentepohlia>> is growing in large clumps everywhere throughout the parque, and on the tops of lots of lichen, super neat, but I´ve tried scratching the surface of some to see if the Trentepohlia is on the inside, but I´ve not really been seeing the classic orange tint in the scratch… maybe I need to wait a bit longer to see color show up…
