Otidea cochleata

Posted by
Johan Dierckx (Wijnegem, Belgium) on 26 September 2010 in Plant & Nature and Portfolio.

Otidea cochleata (Gedrongen hazenoor (BE) / Brown Ear (EN) / Schnecken-Öhrling (DE) / Otidée brun d'ombre (FR)) is a fungus in the Pyronemataceae family which is in the Ascomycota phylum.
All fungi in the Ascomycota phylum have spores that are produced in specialized holding cells called "asci." An ascus (singular of "asci") usually holds eight spores (but the number may vary greatly). The spores are ejected through the end of the ascus, where an opening develops. There is no definitive way to determine, without using a microscope, whether or not a mushroom belongs to the Ascomycota or the Basidiomycota (basidium-bearing fungi). Identification within the genus otidea is very complex so I have to rely on the opinion of some experts for the field-identification (without a microscopic determination) of this specimen.

Si on oublie que c'est une macro, on pourrait presque y voir un cratére de volcan...
J'aime beaucoup votre travail.
Bon dimanche

@Julie: Thank you very much for this nice comment, Julie. Have a nice week !

Veronique from Sarrouilles, France

amazing !! this one and all your mushrooms (how do you see them...do you crawl in the woods ?)

@Veronique: I just use my eyes :-)))) And you can be sure: I just do walk in a normal way :p

hey johan! long time no see - looking at your marvellous shrooms tells me you´re doing fine ;D
i´ve been very busy the last weeks, and also a bit too lazy for commenting and visiting. I´ve found many mushrooms the last weekend, but some of my pityful fellow humans decided to smash them^^

@daniela scharnowski: Hoi Daniela - you're still alive and kicking I see .. :-) Hope you find some unsmashed mushrooms someday - the nicest subject in autumn for me :-)

Julie Brown from Indianapolis, United States

A very interesting structure-the outside texture almost looks like a sponge. So, the spores have been ejected here?

@Julie Brown: The fertile surface in this species is on the inner-side (so the orange part). Sometimes you can see real "clouds" of spores comming out like a little volcano-cloud. Till now I wasn't able to caputure that but I keep trying ... :-)

Gedrongen hazenoor wat een aparte naam, past wel heel goed bij deze zwam.

@carla: Er zijn een hele hoop "hazenoren" bij de paddenstoelen. Ze zijn heel erg verwant met de bekerzwammen, maar hebben telkens 1 opening in de zijkant (die dus niet helemaal sluit). Sommige namen zijn inderdaad heel treffend gekozen (zo heb je ook nog varkensoor, knotszwam, enz ...een koraalzwam liet ik reeds zien) Het geven van een naam die de uiterlijke kenmerken beschrijft is nu eenmaal makkelijker om te onthouden.
Fijne dag, Carla en dank voor je commentaartje.

Een ingewikkeld modelletje met een bijzondere structuur. het lijkt wel of er bladgoud op ligt......!
Het bokeh in de vorm van al die gouden munten past er perfekt bij! Prachtig:-)

@Marleen: Structuren in paddenstoelen zijn ontzettend divers. Ik ben al lang afgestapt van het klassieke - steel met hoed - plaatje :-)
