Fungi are truly remarkable things. The book Entangled Life is quite enjoyable for anyone interesting in learning more about the world of Fungi and their importance to the world.

Anyone interesting in gardening may also be interested in no-dig gardening and permaculture which help preserve the microbiology (including fungi) in the soil.


I wonder if mycorrizhae is extending through the frog's body?

Says this type of fungus is saprotrophic. Hard to imagine anything but a parasitic relationship from the frog's perspective.

But the fungus is mature enough to fruit and the frog is still living??? That is one hearty frog. I wonder if it had a mutation


Assuming it’s not just something that got stuck on the outside, then I would imagine that the frog is immunocompromised in some way, either due to mutation or environmental exposure to something.

Split gill fungus (Schizophyllum commune), is an extremely common saprotrophic (eats dead wood) fungus that is normally completely harmless to humans. However in immunocompromised individuals, it can colonize their lungs and kill them.


> I wonder if mycorrizhae is extending through the frog's body?

Do you mean mycelium? Mycorrhizhae are specialized mycelial structures that interface with plant roots.


Oh yes I meant mycelium, thanks. Getting my jargon mixed up...


Wow, absolutely didn't expect this news to pop out here. I am familiar with the authors.


I bet the frog didn't expect a mushroom to pop out either


Frog not fro. I had visions of truly rank dreadlocks. In which case growing mushrooms is not much of a leap, lemme tell you.


The images were less disturbing than I had expected. That poor frog, though.


I've often wondered if human hair is some how a slightly different organism. But I guess it has the same DNA as the spit from our mouth so I guess not.


Human hair, no. But the mixed-up hairs of this paradoxical being, very much so:

Hair, as in the main shaft outside of the follicle, is mostly keratin and doesn't contain any DNA at all.



A link to the inaturalist observation and commentary from working mycologists: https://www.inaturalist.org/observations/168461910?fbclid=Iw...

(tl;dr image analysis seems to suggest the images haven't been doctored, mycologists like Alan Rockefeller believe it's most likely been dislodged and stuck to the frog's skin somehow, mycena mycelium would not colonise a frog flesh substrate)


Thanks for the link; I hadn’t heard of iNaturalist before and I enjoyed reading the discussion. This particular comment gave me a laugh:

> Would you also deny that a fungus could never fruit the the toenail of a human that spent a lot of time in the Amazon Rainforest?


Yeah, it's a good time =) highly recommend the app! I've learned tons about the natural world in my hometown from snapping pics while I'm walking around. The community is really friendly.


Yeah kinda weird to leave out the iNat discussion. It's a really fun photo but the consensus of "it's a piece of dirt with the mushroom on it" seems improtant if you want to publish it...


Many plants can grow in pretty any much substrate — even just water — as well.

The main issue, assuming the temperature is right, that stunts plant growth just anywhere is that usually there is not enough consistent water, and then eventually the lack of nutrients once the the plant uses its reserves from a seed.

The reason we use soil is because as a substrate, it holds water and nutrients just at the right amount where you don’t have to go out and water it every 5 minutes.

But if you find any pocket made of any material, even a fold of your skin, threw a seed in, and kept it moist by hand, you could grow cherry tomatoes.


Fungus isn't a plant, though.

Mushrooms are to fungus what an apple is to a tree (sort of). They require moisture but their nutrients come from decomposing.

Now imagine what all of this means for the frog.


Tree growing in uncleaned rain gutters: https://i.ibb.co/C6XNxyb/roof-tree.webp


I found that really repulsive for some reason, cool but repulsive.


No doubt this is related to avoidance of parasites and infections, similar to trypophobia.

I looked at the image 8/9 hours ago and I still feel physically sick. Crazy what the body can do just because of a photo... very very weird.


yes, seeing this makes me want to eradicate that fungus from the entire planet


Philosophy: are we quite sure it's the mushroom growing out of the frog? Reminds me of a joke:

A policeman walks into a doctor's surgery with a pig on his head.

The doctor says "errr... I think I can see the problem".

The pig says "yes, I've got this thing growing on my foot".


This poor guy has to turn his controller sideways now


Growing from the frog? Or the splinter in the frog, that was already covered in mycelium?


> The frog was not collected, so no prognosis is possible.


How can we know it was not doctored somehow, since the frog was not collected?


yeah that seems like a very easy thing to fake


Interesting but impossible to prove as there is not any histological research done and could be easily an artifact, or a fake.

As the skin looks healthy around the area without almost no color or texture response

...and the mushroom is displaced from a normal up-down position,

...and the frog is alive and didn't tried to remove it...

...and that we know that this genus of fungus is saprophytic and live on dead plants. Frog skin evolved to have a complex cocktail of chemicals, totally different than dead wood cellulose so, what is this mushroom eating exactly?.

my bet would be that the Mycena is growing on a wood splint in the frog body. This is the safer explanation at this moment with this data.

Mycena grow often on indoor pots at the extreme of sticks when the compost is cheap. Plant owners always are alarmed and ask about it.

I'm not against changing the paradigm but would require much more solid data than this.


Reminded me of the Hacker News thread "A Planet of Parasites and the Problem with God" : https://news.ycombinator.com/item?id=38897960

Gotta book mark the article as it's an interesting take on how the world runs. From the article:

"Is There Any Meaning to This Shit Show?

Optimists generally feel a strong need to believe in a benevolent universe. Hey, I get it. The idea that we live in a universe that is pitiless and meaningless [...] is a bitter pill to swallow. It would be so much nicer to believe that we live in a benevolent universe, looking out for us and helping us along. But how can one believe in a benevolent universe that contains such extreme, pervasive, gratuitous violence, predation, and suffering?"


Something for him to eat later.


So, what happens if you lick the frog and eat the mushroom?

Someone should try.. You know, for science!


is that good


Title should be updated: “Frog”, not “Fro”.


Yes, for a second before it loaded, I really did think I was going to see some kind of psychedelic or 1970's retro fashion. Wasn't sure what that would be doing on HN, but there have been stranger things on the front page!


The guy walking around San Mateo County with exposed brain due to cancer takes the cake. https://www.snopes.com/fact-check/maggot-brain/


Warning to anyone who clicks the link: It’s real, and there are photos. Do not click the link.


Heeding your warning, but I have to ask: how much? Like, just a little? Or cartoon throbbing cranium?


It's difficult to believe the man was in no pain and did not seek medical care until he was involved in an automobile accident. I've hit my head a few times on cabinets and it would have sort of lobotomized this guy.


Yikes! Well, that's a vivid picture alright :P

Regarding the pain, though, don't they say that your brain has no pain receptors? Granted, there's gotta be a difference between being awake for brain surgery and walking around like that, but...


True, but I imagine showering or bathing one's hair in that condition would be precarious proposition, one could use a bathing cap while doing rest of body but that would still leave the undamaged head parts needing a wash.


The latter, except way more graphic.


There is an ascetic in India who claims to have rice growing out of his hair. That’s kinda what I was thinking.


After Googling, it appears to be a thing and is very green.


I was expecting some hippie with unwashed, blonde, hair with mini bellas growing off her hair.

I was a bit disappointed, although I guess biologically this is weirder.


Is it weirder though?


Mushroom growing out of living skin tissue vs dead hair is absolutely weirder.


Hair isn't dead. It's not cells at all, just extruded protein. But that's largely beside the point.


"Dead" in the "nonliving organic material" sense. It seems much easier for mycelium to survive in something incapable of an immune response vs. living tissue. And yes, largely besides the point indeed.


Hair is composed of dead hair cells.


'dead hair' is a tad redundant, innit?


Yes, I was not disappointed. Even though I still would like to see a Mushroom in a fro, frog mushrooms raise more questions.


I thought I was about to read a very different article.


Something something.... game about zombie fungus.


First part, or the other part?


Sigh, we were warned
