Incubation temp, dangers??

Hello fellow myco-nuts . Its been 3 days since i have started my first set of PF jars. There's 12 all together. I had them stacked in a small box above my refrigerator well i was making some tacos the other night and i realized i should check my temp. It was 95f (normally it was a GREAT 86f)!! It was only like that for 10 minutes max. and the jars where wrapped in a blanket inside of a box close together. Do you guys think i may have destroyed my spores? I think that them being huddled together and in the blanket may have saved me ruin (the heat would take more than 10 minutes to disperse to the jars and raise there actual temp? )
I'm just kind of worried, I've read that spores die from high heat. But i have never been able to find the exact temp they die at?
So my question is do you guys think i ruined em? And at what temp do the spores get killed?

spores die in the 150s, and after a bit of time at that temp (quicker at higher temps). you're right that even if the ambient temp got up to 95 it would take some time for the jars to warm to that. no harm done.
keep an eye out though. growth slows once you go above 86, but bacteria thrives. if you had to choose between 95 and 70 (room temp), they'll go similar speeds but 70 is safer contam wise... so if there's a risk temps will regularly raise that high just leave them at room temp and play it safe. they'll still colonize.

Substrate Temperature: 28-30°C. Thermal death limits have been established at 41.1°C. 105.98*F you should be OK man

that's thermal death for vegetative mycelium, and again isn't instantaneous, they have to be held at that temp for a bit. ungerminated spores can withstand a bit more.
