is it possible to get them somehow in Kunming?

You think this is a good place to ask?

yes,I know there has a mushroms whole sale market,near International Trade Exhibition Center on chunchenglu,the name is shui mu hua whole sale market(水木花批发市场）,this is the dry mushroom,if you want buy the fresh mushroom,you can buy in any market..

Either I'm overly-suspicious, or rose is a touch naive.

What kind of 'shrooms you after exactly there trolluz?

A true local Kunming phrase for someone acting crazy....

"What kind of mushrooms have you been eating?"
