Winter green house, can fungi handle temp range day-night?

I'm on the West coast of Canada in Pacific North West weather conditions. Over winter, day time temps can hit 12-15C (53-59F) and night can be hover just above freezing. I'm going to be growing oysters and maybe some other varieties (still researching) in an unheated greenhouse that I've been experimenting in already to supplement our winter farmer's market. So I'm only planning to do about 40-60lbs a week using our farm's hay (supplemented). We get enough thermal energy from the sun that our greenhouses can rocket up to 30-40C (86-100F)day time temp if we're not careful, but we can maintain around 15-25C (59-77F) with proper ventilation techniques. But at night a greenhouse will drop to almost freezing or 5-10C (41-50F) depending on how cloudy it was during the day.
Q: Can mushrooms handle that type of swing? For example, I know the "fruiting temp" of lets say Blue Oyster will be between 5-15C. So I am confident we can balance that between day an night. But let's say I was to grow something that fruits between at 15C. What would happen to the fruiting body if it starts to pin but then has to go 12 hours hovering above freezing? Does growth just slow or would a strain that fruits around 10-15C die? Yes, I'll do spawn runs in a warmer, more consistent area. I can also choose to put the greenhouse in full sun or in our wood lot (where it is now to protect it from getting too hot). If I leave it in the wood lot, the temp range would be much smaller but I'd be stuck with only varieties that fruit at above freezing to 10C (basically the greenhouse is only a few degrees warmer than outdoor temps). Or I can stick it in full sun and try juggling with ventilation to get more varieties.
If you also have suggestions for varieties, I am all ears. Thanks everyone.

My trade list Looking for strong terrestrial fruiters for an outdoor beds experiment: Agaricus Bitorquis, Agaricus Augustus, Agaricus blazei/subrufescens, Stropharia Rugoso-annulata, Clitocybe Nuda (blewits), and any species or other genus that you think work outdoors. Also, any commercially viable Pleurotus, cold or hot strains. Thanks for the Q&A, trades, and all the posters & teachers that have come before us

Here is a grower in BC who does outdoor, but he only does his season, i would assume too much cost to heat.

WTF Mushrooms goes all year, they just select the proper species (maybe take a month or two off). He does seasonal mushrooms, meaning he changes his varieties with the seasons. We also have a slightly different climate where I am compared to him. We probably get more sunlight and therefore warmer daytime temperatures. Those warmer day temps is precisely my concern since I'd have way bigger temp swings in a greenhouse. But, that could also work to my advantage, hence my original Q (especially if I instead dedicate some of my growing space to thermal mass to raise my night temps)).

I meant solar energy, obviously.

Temp swings are fine. To keep temps above freeizng you might want to consider some sort of thermal storage like tanks of water or passive solar heating.

Thanks for the affirmation Gr0wer. I know with different plants they can sustain like 24 hour or 48 hours of freezing and not die. Are there similar thresholds with fungi (yeah, acknowledging each strain is different)?

Yeah you can have blue oysters freeze and thaw and grow. They aren't real pretty but it works. For a viable commercial operation probably not, but for home consumption it's totally fine.
