I know chlorociboria …. and your not Chlorociboria

I’ve seen a lot of Chlorociboria aeruginosa, it’s pretty common some years here in the Pacific Northwest. I can say with total confidence and certainty that is not Chlorociboria. What it truely is, I leave to those more skilled than I.

nor sit beside a plasmodium with many hours patience, in order to identify one (the visible slime is a good queue to suspect slime mold). i amend my earlier statement that we are seeing a plasmodium. there is some plasmodium and at least four distinct aethelia, all of a shape, size and color consistent with Dictydiaethelium.

what I stated. Both stain their substrate wood blue-green.

I cannot tell if this is plasmodium: I have not seen it move. I rather doubt you have seen it move too, Danny. Your reference to this definately being a plasmodium clinches that thought.

Please confine yourself to the photos at hand.

both C. aeruginosa and C. aeruginascens produce blue-green apothecia. David may be confusing his description with species of Chloroencoelia or Chlorosplenium, the latter having housed species of Chlorociboria at various times. I have never seen orange flesh in Chlorociboria fruiting bodies, but who knows.

more to the point, this is a plasmodium, not perithecia, and it’s uniformly peachy orange-pink, not blue. i don’t see whatever stain you’re referring to, but if I did, it would not change the highly non-Chlorociboria-ness of the specimen pictured.

even more to the point this is Colombia, not North America or Europe, and here we are deliberating… again… over a description in a field guide written for the Western United States.

You have other sources?

MD says: “C. aeruginosa is a very similar, widely distributed species … has a shorter, more or less central stalk, and orange-yellow flesh. Both species can be detected when they are not fruiting because their mycelium stains the host blue-green.” This appears to have orange-yellow flesh and stains the host wood blue-green.
