  1. What a beautiful aqua blue and cracking macro work. I'm sure I've read somewhere along the way that blue-stained wood was highly prized for woodwork centuries ago. Maybe a specific species that made a certain hue? Posted one year ago
    1. When it's not fruiting, Chlorociboria makes the blue wood - I find the blue wood a lot more than I see fruiting bodies. In the NE US, I tend to see the fruiting bodies in the fall, but the blue wood year round. I'll have to take some shots of the blue wood to post because it's really beautiful! Posted one year ago
      1. I forgot that I had already taken this one photo at least ;P

        Chlorociboria-Infected Wood - Chlorociboria sp. Beautiful "blue wood", which is characteristic of wood that has been infected with Chlorociboria fungus.  No fruiting bodies were present. I found this wood in a swamp, where I was searching for frogs.<br />

Chlorociboria species contain a napthaquinone pigment called xylindein, which is the reason for the characteristic bluish-green stain that occurs on wood that's infected by this species.<br />

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 1-2┬Ám the spores of Chlorciboria aeruginascens are significantly smaller than those of Chlorciboria aeruginosa (9-14.. more
