Appearance
Although C. aeruginosa tends to be a little smaller and very much rarer than C. aeruginascens, the fruitbodies of the two species cannot be confidently differentiated on macroscopic characteristics, but at 5-7 x 1-2µm the spores of Chlorciboria aeruginascens are significantly smaller than those of Chlorciboria aeruginosa (9-14 x 2-4µm).Both species are more often seen in the form of green-stained wood than when when they are producing fruitbodies, but past records made without microscopic study of specimens may have confused the two species.

Distribution
This ascomycetous fungus has a very wide geographical distribution that includes Europe and North America.References:
