Best way to store mushrooms?

You will notice that mushrooms in the grocery store are displayed in the open refrigeration case--they need to be cool, but not cold. If your kitchen is generally cool and you plan to use your mushrooms within the next day or two, keep them on the counter in a paper bag. If your kitchen is warm or very moist and you're not sure when you will use them, put them in the fridge.

Put them in a paper bag - not plastic - and keep cool or in fridge. Fridge will add a couple days. Best to shop daily for what you need daily.

I'd put them in the fridge. (And I'm not usually much of a refrigeration person.)

Is room temperature OK, or should I put the paper bag in the fridge? Thanks!

They need to breath without drying out or getting too moist. a loosly closed paperbag usually does the trick
