Spore hardiness

If mushroom spores are able to survive the temperature, vacuum and radiation of interstellar space, are spores able to survive the temps and pressure of a PC?
I'm pretty sure that I've seen a documentary about panspermia that ran computer simulations to confirm that spores could handle interstellar transit and earth orbit re entry. The name of the doc escapes me.

PC temps will kill spores.
Im not even going to tell you my opinion of panspermia.

If panspermia is a thing, I think it is that complex carbohydrates seeded the earth from orbit (maybe some small amino acids or rinonucleotides) there is no way any organism that we know could survive leaving a planet, traveling at least half a year in space and then enter earth before growing.
Spores die in the PC, that is exactly why we pressure cook things, to kill spores from everything else.

I understand that the purpose of the PC is to kill spores and bacteria, however.... is anyone aware of the specific temp ranges and pressures that spores can survive, specifically spores that are worked with on this forum.

I didn’t rhink the thermal tolerance is very high.
I would imagine that it would change in a dry environment vs moist.
For example, I believe 90F and up can kill spores (if you inject into a substrate that has not cooled enough) but I would imagine that at least some spores would survive higher temps with no moisture (like 100 deg F in a dehydrator). I can say that spores will not germinate after 12-24 H at 160 def F (after 3 weeks on agar and including a few days in a syringe)

Pressure is literally linked to temperature, soooooo.... you can do some maths and stuff once you get the thermal tolerance

Bro. Water bears are incredible and can endure some crazy shit, but they wouldn’t survive space for months and might not be able to endure reentry into an atmosphere. Let alone leaving the atmosphere of whatever planet the came from and what method would catapult them into the stars?
That being said, if they could, they would perish upon finding them selfs in a new planet with nothing to eat.
There is a difference between an organism that can endure some shit, and an organism that can seed life on another planet

Asteriods? Meteorites? There are theories that waterbears did not originate on Earth and they're thriving here now.

The longest report of water bears surviving radiation from space is like 10 days.
Months (at veryyyyyy minimum, think of how far mars is) in a vacuum with radiation, extreme heat and cold... I don’t buy it.
Plus they have too similar genetic structure to have originated elsewhere. I don’t think there could be that deep of homology...

If spores made it to earth from another planet they survived space because they live inside meteors protected from radiation, heat, and whatever else there is out there. They dont even need the high temps of a PC, im pretty sure they cant survive anything hotter than tea for very long or even UVC light.

Shouldn’t this belong in advanced mycology?

No it’s a pretty basic question.

Super basic and not too difficult to find out on your own with some cursory google searches,it stimulates conversation.
