For the mushrooms. 1870 66, 5h55, 5 Ivan Ivanovich Shishkin (1832-1898)

The picture has something of this: tree, outdoors, nature, landscape, leisure, recreation, grass, wood, park, relaxation, summer, daylight, leaf, sky, people, scenic, water, countryside.
Perhaps it’s a painting of a group of people sitting on a grass covered field next to a body of water with a tree and other people in the background.
