Moss. Roots. Etude 26h36 Ivan Ivanovich Shishkin (1832-1898)

The picture has something of this: water, landscape, nature, tree, wood, river, outdoors, environment, mountain, rock, scenic, moss, fall, leaf, park, hill, scenery, lush.
Perhaps it’s a painting of green moss growing on a tree trunk in a grassy area with trees in the background and a blue sky in the middle of the painting.
