Maybe Sheldon will know this:

I used to buy small packages of dried, black mushrooms at the grocery
store. These were not terribly expensive, were definitely nothing
Oriental and were, I believe, the kind that were put into the tubes of
mushroom barley soup mix by Manaschewitz and Streits, two Kosher
companies. They were sold right next to the aforementioned dried soup
mixes in the Kosher foods aisle.

They don't have them down here and DIL could not find them in NJ,
where I used to get them.

I want to buy some on line, as I like making mushroom barley soup, but
miss the strong flavor of these mushrooms.

They may have been Polish or similar to Polish mushrooms.

I need a name for these mushrooms so I can buy them.

Can anyone help?
