Lichens are things (files.catbox.moe)

image transcript:

the lichen knowledge iceberg i have constructed on request.

jhanettesticle replies:
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?

bogleech replies:
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.

For anyone else who was curious about lichens covering "a not insignificant amount" of the earth's surface, a quick google tells me it's about 7% (according to e.g. new york times, scientific american, etc)

Edit: oh and estimating the age of an exposed surface by lichen diameter is called lichenometry. I'm seeing stuff about it being used in geological contexts but it makes sense that it could work for old buildings too

We can't even grow most bacteria in labs. It's a pretty small subset that work with the traditional agar petri dish set up.

[–] stelelor@lemmy.ca 27 points 2 months ago

Gotta love oligotrophy. Some lichens grow inside rocks... definitely can't replicate that in a lab (although not for lack of trying).

[–] nickwitha_k@lemmy.sdf.org 19 points 2 months ago

We can't even grow most bacteria in labs.

And that doesn't even get to the level of Archaea. Some of which we only know about because of genetic material.

[–] voracitude@lemmy.world 47 points 2 months ago

And I thought mushrooms were complicated...

[–] Draegur@lemm.ee 45 points 2 months ago

i imagine alien hivemind organisms looking at earth and our cities upon it and thinking "what are these growths and why aren't the samples we collect producing them?"

[–] Generous1146@beehaw.org 41 points 2 months ago (1 children)

Id watch a 2h youtube video about this 👀

[–] deuleb_biezelbob@programming.dev 27 points 2 months ago (1 children)

I'd sink a months worth of time and ADHD medication on this

[–] deuleb_biezelbob@programming.dev 18 points 2 months ago* (last edited 2 months ago) (1 children)

oh my god @nicknonya@lemmy.blahaj.zone what gave you done. here goes my free time

[–] nicknonya@lemmy.blahaj.zone 16 points 2 months ago

i'm sorry, i know not the power i wield

[–] gravitas_deficiency@sh.itjust.works 41 points 2 months ago* (last edited 2 months ago) (1 children)

I would like to propose an addition to the Forbidden Knowledge list:

  1. Do not teach crabs how to read
  2. Do not tell any lichen that “red wunz go fasta”
[–] thegreekgeek@midwest.social 19 points 2 months ago

Will we get Orkz one day when some mad scientist decides to cross lichen with Florida man?

The short answer: fungus and algae work together and create a multi-organism structure.

The medium answer: [this meme]

The long answer: [years of graduate school]

[–] anarchrist@lemmy.dbzer0.com 45 points 2 months ago (1 children)

It's a thing that grows on trees and rocks mostly, but can and does grow on basically anything in the goldilocks conditions. They feel like crispy moss if you touch them.

[–] dogsnest@lemmy.world 15 points 2 months ago (3 children)

They thrive in graveyards...

To those unfamiliar, this is the translation from goth to non-goth. Any non-goths hearing Robert Smith here make this statement would perceive someone closer to:

~me too~

If

*off screen* me too!

makes more sense to me than

~me too~

Does that make me a goth?

[–] nickwitha_k@lemmy.sdf.org 3 points 2 months ago

I'm sorry but, I'm not a physician and thus am not qualified to provide medical advice.

[–] troyunrau@lemmy.ca 4 points 2 months ago

Just need to build a lab in a graveyard then. Checkmate lichens!

[–] aStonedSanta@lemm.ee 4 points 2 months ago* (last edited 2 months ago)

What if it’s how our souls are released. Man I’m high and that thought still gives me the call of the void lol

[–] kartoffelsaft@programming.dev 34 points 2 months ago

I'm no biologist, but I'm pretty sure that this photo I took a while back has a lot of lichen:

That flakey & coral-looking stuff growing on the branches should be lichen.

[–] ryannathans@aussie.zone 29 points 2 months ago (1 children)

It’s the opposite of not lichen.

And that’s both a pithy retort, as well as an accurate reflection of the ultimate gist of the infographic lol

[–] RizzRustbolt@lemmy.world 7 points 2 months ago

A containment protocol for an ancient plague.

[–] thejoker954@lemmy.world 29 points 2 months ago (1 children)

I've never thought about it. I always just assumed lichen was just a specific type of moss.

[–] WanderingVentra@lemm.ee 21 points 2 months ago (2 children)

Same. The more I learn about fungus and their related kin, the more I realize I don't get them lol.

[–] scrion@lemmy.world 14 points 2 months ago (1 children)

For anyone interested, I really recommend the book / audio book Entangled Life by Merlin Sheldrake.

I liked the book so much that I later on bought the audio book. It's entertaining, filled with facts, but not overly scientific to a degree where it can't be enjoyed by a layman.

[–] WanderingVentra@lemm.ee 3 points 2 months ago

Thanks! Definitely saving this comment for future reading.

[–] dylanmorgan@slrpnk.net 14 points 2 months ago

To be fair, based on mycology memes I’ve seen nobody gets fungi or their kin. (Nobody who knows enough to listen to, at least.)

Bless you for doing the work of the Lord (Lichen Out to Read Dis)

[–] fossilesque@mander.xyz 13 points 2 months ago

Meanwhile, it's BFF moss is something like 90% dead plant matter and just a derpy slow sponge. Pinky and the brain.

[–] Shhalahr@beehaw.org 11 points 2 months ago (1 children)

So, I opened this without looking at the source community. I'm on an RPG meme community as well. I was actually predicting a pun on a certain phylactery-using undead. Only as it was loading did I realize I had a chance for the science memes sub instead.

[–] nicknonya@lemmy.blahaj.zone 10 points 2 months ago

i did try to work a lich joke in the title but i couldn't think of anything natural or forced enough to be funny. submissions are open though

[–] Telodzrum@lemmy.world 9 points 2 months ago (3 children)

For fun related fiction viewing, I recommend the horror films:

Both are about "what would happen if nature got mad?" No, not like The Happening

[–] Zoomboingding@lemmy.world 9 points 2 months ago (1 children)

Does "The Last Of Us" count here?

[–] Telodzrum@lemmy.world 7 points 2 months ago

Probably should, right?

[–] aStonedSanta@lemm.ee 3 points 2 months ago

The happening. Man I’m still mad I spent time watching that. And I really don’t value my time lmao

[–] JimboDHimbo@lemmy.ca 3 points 2 months ago

Omg thank you, I've only seen Gaia once but I loved it and I forgot the name!

[–] Angry_Autist@lemmy.world 9 points 2 months ago

I fucking hate the fact that this 100 story tall image format has become the default on the internet...

What I got out of this is that Dax from DS9 was probably a lichen
