If you're referring to agaricus bisporus (portobello), then yes they do carry spores in stores most of the time.
The problem with growing from a grocery store is finding a piece of sterile inoculant to drop onto agar, because those mushrooms have likely been shipped across the country.. if not across the world, they will likely be full of contaminants.
I was going to make an effort to grow these and I ran into this. Along with the difficult grow parameters (fruiting temps around 55-60F)

From the freshest specimen you can find, take at tissue culture from the inside of the stem to start a culture on agar, or for some spp., wet cardboard. Can work for any fresh mushroom from your grocer, or wild-gathered also.
-------------------- Rocks speak to me, and tell me this: The Hell Creek formation is a gigantic slab of rocks that covers several western states. It contains an account of the dinosaurs' demise. In the late Cretaceous period, the first Cannabis species appear, and soon after, all the non-bird dinosaurs disappeared. Obviously, marihuana killed the dinosaurs. That giant meteor that smacked the yucatan peninsula right afterwards, coincidence.

I would only take tissue samples and place them on agar (not cardboard) so you can transfer away from the contaminants that you're likely to get from grocery store specimens. Even then though alot of the ones you would get from the grocery store might have been pushed as far as they can and senescence might set in very soon.

SWEET!!! Cant wait to try this out! Would u guys say such fruiting temps from 55-60 are in all if not most grocery mushrooms? Sounds like they engineered them that way so people wouldn't try to grow them:)
