Extract from Wikipedia article: Chlorociboria aeruginascens is a saprobic species of mushroom, commonly known as the green elfcup or the green wood cup because of its characteristic small, green, saucer-shaped fruit bodies. Although the actual fruit bodies are infrequently seen, the green staining of wood caused by the fungus is more prevalent.
Chlorociboria aeruginascens is a species of fungus that belongs to the family Chlorociboriaceae. It is characterized by its green-blue to blue-green staining of wood due to the production of the pigment xylindein. In St. Petersburg, Leningrad Oblast, and north-western Russia, Chlorociboria aeruginascens has been found growing on decaying wood, particularly on coniferous trees such as spruce and fir, in moist, shaded areas with rich soil. The fungus is relatively rare in the region, but can be locally abundant in suitable habitats, including old-growth forests and woodland edges.
