A photo of the left page of a portrait-format black paper sketchbook, placed on a wooden desk and surrounded by a snippet of a painting, a gouache tube, a paint brush, coloured pencils, fluorite crystals, branches, and leaves. The sketchbook page is titled „Symbionts of Betula ignea“ and shows a colourful illustration of the fictional tree as well as close-ups of three symbionts. The tree itself is a twisting birch with a distinctly flame-shaped crown, golden foliage, and grey bark. Small purple and teal mushrooms grow on its trunk, and golden moss at its base. The close-up of the oblong, glowing purple mushrooms reads: Coprinus luminosus (Luminescent Coprinus). The close-up of the moss reads: Plagiothecium aureus (Golden Sheath-Moss). The close-up of the small teal glowing mushrooms reads: Psilocybe caerulea (Cerulean Flesh of God). Under the tree a note reads: „Habitat: temperate deciduous forests“.
