Elfcups - Chlorociboria aeruginosa
This is a really big crop - these cups are normally 1-2 mm in size, but in their current dried up state, they were even smaller.
Here is what they looked like about 3 months earlier:
Habitat: Growing on rotting, decorticated wood in a mixed forest.
Chlorciboria aeruginosa is one of just two species recorded in the genus Chlorociboria, the other being Chlorociboria aeruginascens. Both result in green staining of timber. 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.. more
