the lichen knowledge iceberg i have constructed on request
we cant make lichen happen in a lab? have we tried taking the parts that make up a lichen and throwing them together in a petri dish?
The deranged fucked up dark sided thing about lichen is that the exact species comprising it don't even necessarily determine the type of lichen. You can have what seems to be the same lichen in two different locations using different symbiotes, or two different looking lichen turn out to have the very same symbiotes. So it's not even that they form when the right component species meet up, because that doesn't always have a predictable result. Something in the environment tells them to build a lichen. Something that makes sense to them but has no meaning to us yet. Whatever it is cannot be imitated by us, in fact if you move a lichen indoors - or move it at all, really - it's all but guaranteed to stop being a lichen or just due, even if you try to recreate the climate you found it in!
Only one truth is certain:
Lichens are things.
