I was reading the Wikipedia article on Armillari. It's a very interesting beast, with about 10 species. Some of the largest organisms on earth are Armillaria. They grow on dead tree roots and other dead tree material, sometimes killing the tree to make more dead roots. Your pictured group appears to be growing among elm sprouts, perhaps coming up from roots of a cut back tree?

Armillaria are considered great delicacies in eastern Europe, but not all species are directly edible, requiring boiling first. One species (in U.K.) does not mix with alcohol.

It would be nice to get a good identity on your new crop.
