So, fungal spores are literally everywhere, and the requirements for fungus to thrive seem to be trivially low; give it a moderately humid environment and it’ll grow on a bare concrete wall ffs eating god only knows what; the dust from the air maybe?
Well, and the great outdoors is full of slightly damp places, many of them downright soggy most of the time - and absolutely rife with organic material to snack on.
Where’s the bottleneck? Why isn’t the world a choking fungal hellscape?
Spores are everywhere like you say and you only really see a tiny percentage of mycelium. Fungi kinda is everywhere already, but where it can grow well is much more limited.
Fungi can be remarkably picky about its growing conditions to thrive, otherwise, it’s growth will be remarkably slow. However, if you put a tablespoon of dirt under the microscope, there could be dozens of mycelial strands in it trying to survive. They can all survive, to a degree, but there are a couple of issues preventing dominance.
If it can find a place to settle in and grow, chances are that many other spores may be trying to take hold as well. Fungi is insanely competitive and is constantly fighting for space. Fast growing fungi is what we normally see take over food sources and it’s usually a type of trichoderma. Trichoderma will literally choke out other fungal growths simply due to its rapid development. If an existing colony is weakened for one reason or another and it gets a trich infection, it’s game over.
For commercial mycelium development, (button mushrooms, oysters, etc.) growing conditions are generally perfect and the substrate used is tailored specifically per species. (It’s mostly sanitized poo or specific types of wood.) Temperatures need to be adjusted for each growth phase as fungi can be very sensitive to that. Some strains of shiitake are rumored to require a physical shock to fruit. (Like, the substrate bag needs to be physically smacked hard. It’s an odd characteristic.)
To sum all of this up, it usually comes down to competition. Where there isn’t fungi, there is bacteria. Plants even have chemical defenses to both. Small critters and insects may eat all three of those things.
Next time you look at your garden, just remember you are looking at an actual battleground for millions of critters of all shapes and sizes.
Thank you for contributing to make the fediverse a more interesting place.
Sure thing. I like to share stuff since I do a lot of random stuff. I also like to learn new things so I try to make it a habit to appreciate any corrections people make to what I say. Live, learn and share!
I have read somewhere that shiitake, and many other mushrooms from Japan only fruit when shaken hard because it has developed in an earthquake prone country.
The other theory is that mycelium starts to develop in a tree that is about to die, and when the tree falls, that is the trigger for fruiting.
(I personally have no clue where these theories originated from and can’t speak to them.)
FYI, your Lemmy client did a triple post from Lemmy world and it exposed your alt on .ca.
What does “exposed your alt on .ca” mean?
Can you intertwine Lemmy accounts from different servers somehow?
The exact same comment was posted from a Lemmy World account 2-3 times, and once from another account on Lemmy .ca.
My wild speculation is that the user made a comment, it lagged, the refresh button was hit a couple of times resulting in multiple POST commands. Maybe the session continued to appear lagged for the user and they switched accounts, resulting in yet another duplicate POST being executed with the new session token. Again, that is just speculation.
In my experience, dupe comments are common with phone clients, either on Lemmy or Reddit. I suppose the same could happen with PC browsers if there is system or VPN lag.
I remember a House episode where people got fungal infection in California after a small earthquake/tremor.

Mold needs the proper conditions to grow.
Probably most important to your question is nutrients. Mold needs certain nutrients in order to grow, which is why it doesnt grow on everything. Some materials that have the nutrients mold needs include various foods, drywall, cotton, and some types of wood.
Mold also need decently specific moisture in its evironment (humidity of over 55%), a proper temperature range, shielding from UV rays that kill it, and if these conditions are met, mold can grow in about 24-48 hours.
it is a fungal hell scape, Valley Fever https://en.wikipedia.org/wiki/Coccidioidomycosis
Ringworm, Yeast infections
if you have a weakened immune system. It’s a nightmare you have to take so many precautions.
Aaaand then there’s slime moulds. Some of which can run a maze…
It’s not a fungal hellscape because the rest of us live at the mercy of fungus.
TIL fungi domesticated everything else on earth.
I, for one, welcome our new mushroom overlords.
