Mushrooms loom in small plastic boxes, and that's it, in my neighbohood. Of course there are better choices elsewhere in the city markets, but those are a trek. I used to haunt international markets or other interesting markets, but not lately. No problem, I still like even these ordinary store mushrooms, no matter what I'm used to. I doctor them... Haven't run into any moldy ones, eeeek! Back in northern California, my then ophthalmologist and her husband were mad mushroom hunters; I listened, but not planning to do it, didn't memorize where they explored. I'd call then avid.
