Chlorociboria aeruginascens

Chlorociboria aeruginascens (NL: Gewone kopergroenbekerzwam / EN: Green elfcup, Green wood cup / DE: Kleinsporiger Grünspanbecherling / FR: Pézize turquoise, Pézize bleu-vert) is a saprobic species of mushroom with 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. The specific epithet is derived from the Latin roots aerug- ("blue-green") and ascens ("becoming"). This species contains a quinone pigment called xylindein. It is this compound that is responsible for the characteristic bluish-green stain of wood infected by this species, used today in decorative woodworking such as Tunbridge ware and parquetry. The use of this wood, known as "green oak", goes back to 15th century Italy, where it was used in intarsia panels made by Fra Giovanni da Veroni.

That's a neat shade of blue. Good focus as always.

@Jaytee: Thanks Jaytee ! It is really a strange colour to find on a fungus in nature. For me the first time to find this species but I'll never forget this one.

Schon wieder so ein besonderer Pilz ! Ich schaue vielleicht doch zu viel in die Luft, daß ich solche Schönheiten nicht sehe !

@Loner: It would not be the best idea for both of us to go on a fototrip together: Me looking always to the ground searching for little details, you looking always to the top of the trees and the sky looking for birds ... We'll definitely need someone to keep us on the right path without bumping our heads upon every trunk ...
For me it was the first time to see this species and it seems to be rather rare in Belgium. I read somewhere that this fungus should occur more in mountain-forest areas of Middle-Europe - so maybe in your region it can be found too... Good luck !

Wat een mooie soort heb je hier vastgelegd, wat een kleur zeg!

@Lia: Een heel rare kleur om in de natuur tegen te komen, en zeker voor een paddenstoel. Blijkbaar is het een behoorlijk zeldzame soort in onze regio en vaak vormt ze ook geen vruchtlichamen maar zie je enkel de kopergoene verkleuring van het (rottende) hout. Dit was dus wel een heel bijzondere waarneming voor me. Fijne dag nog !

Ik sta al verbaasd te kijken als ik een oranje paddootje tegen kom, laat staan deze waanzinnige kleur! Prachtig tegen de bruine omgeving.

@Monique: Ja, eens je deze gezien hebt, laat de kleur je niet meer los. Een van de vreemdste kleuren die ik tot hiertoe tegenkwam in de paddenstoelenwereld ....
