These colours mean that Parmeliaceae is dying

These colours are common for dying Parmeliaceae also in Kazakhstan.

Discoloration is from environmental stress

Could be pollution, or maybe nearby trees were cut down, or if this was on a fallen limb it’s getting a whole lot less light than it’s used to, or maybe a dog peed on it, or…

In short: it’s dying.

[Oh, sorry, I just saw that you said the area had recently burned. That’ll do it for sure!]

What’s up with the color?

Looking at pictures of Flavopunctelia soredica online, they seem to mostly be green. Are the colors of this specimen typical for this species? Do you think its color could have been modified by a prairie fire? The ambient air temperature probably increased, but I imagine the burn was probably not so intense that the flames made it to the height of the lichen. Fungi on trees closer to the ground were burned and blackened.
