Observation 88813: Cantharellus melanoxeros Desm.
When: 2011-09-25
No herbarium specimen

Notes: This mushroom was found on a foray that Italian mycologist, Silvano Pizzardo organized with Ennio Giusti and Albert Casiero. Local area mycologist, Anna Maria Marini, identified this mushroom as Cantharellus ianthinoxanthus in the field and after the foray the ID was confirmed by Sivano Pizzardo, “Coordinator pro tempore” of the Federation Veneti (Mycology) Groups.

I missed them the first go round.

What a fascinating fungus! Oh yeah, these are surely Craterellus rather than Cantharellus…Craterellus in the sense of yellow foot chanties, not black chanties.

Are they hollow?

Love the ball-like cluster, too. The blackening is just a bit of gravy…these are so distinctive already!

Thanks for posting.

Silvano Pizzardo agrees that C. melanoxeros is the correct ID.

I finally got around to requesting Silvano Pizzardo to re-examine this mushroom. Looks like he had just rubber stamped the field mycologist’s ID before without really looking at it, because he now says it’s clearly C. melanoxeros. This is his description.

“Quanto alle due specie ritengo siano entità simili ma specie autonome. In Italia, scambiate per C. cibarius e consumate, stanno diventando rare e forse scomparendo come anche da notizie europee. La differenza tra le due sta nel colore della carne.
Cantharellus ianthinoxanthus ha carne non annerente e pseudo lamelle grigio-lilacino, a pliche anastomizzate-reticolate poco salienti e molto fitte e tende a crescere gregario non cespitoso. Cantharellus melanoxeros ha la carne spiccatamente tendente ad annerire, imenoforo con sfumature azzurrognole. Entrambi crescono sotto latifoglia in particolare Faggio. Le mie raccolte si contano sulla punte delle dita. Anni orsono rinvenni C. melanoxeros in Emilia Romagna.
La tua raccolta è sicuramente C. melanoxeros.”

Really one species?

I think without dna analysis and knowledge about the phylogeny it’s difficult to say that the two taxa are identical.

C. melanoxeros De sm.=C. ianthinoxanthus (Maire) Kühner ie synonymous

After google searching for images of both species, I see so much variation in all described characteristics with each species that I’m leaning towards the conclusion I see given in several sites of synonymy such as "blackening chanterelle C. melanoxeros Desm.=C. ianthinoxanthus (Maire) Kühner (from http://www.scribd.com/... p.78 Ecology and Management of Commercially Harvested Chanterelle Mushrooms
David Pilz, Lorelei Norvell, Eric Danell, and Randy Molina

So these species are another good candidate for DNA comparison, and
if synonymous, I suppose the earlier assigned name, Cantharellus melanoxeros Desm.(1830) takes presidence though some mycologists have put it in the Craterellus genus as Craterellus melanoxeros (Desm.) Pérez-De-Greg. 2000.

…for the lit. cite. I’ll see how far I come with online translators…

I asked in a few German forums what species the photos could showing. Eric Strittmatter, owner of Fungiworld.com, recognizes C. melanoxeros. He knows the species from the “Schönberg” in the Black Forest/ Baden-Wuertemberg. Especially the surface of the caps is distinctive.
Also Andreas Gminder, a mycologist from Jena/ Thüringen, wrote, that the photo is showing C. melanoxeros:

“Apart from the blacking, which can occur at C. melanoxeros quite late, C. melanoxeros has a clearer edged hymenium and slightly different colors in comparism with C. ianthinoxanthus. C. melanoxeros has rather a purplish to grey-purplish colored hymenium and a grey-yellow cap. C. ianthinoxanthus has a (weavly) more violett-pink colored hymenium and a brighter orange-yellow colored cap. The fruitbodies of C. melanoxeros grwos bigger and distinct formed caps as C. ianthinoxanthus.”

Andreas’ partner Tanja Böhning has uploaded two aquarelles of C. ianthinoxanthus and C. melanoxeros to compare them – special thanks at this place:

And here I’ve found a good photo by Thomas Lehr which shows C. ianthinoxanthus:

Hymenium looks yellow to me

The hymenium does not look “more dark-colored …gray-violet”.

for this translation—

The closest species with which could be confused, is Cantharellus ianthinoxanthus (Maire) Kühner, the which has been considered synonymous for a long period of time. The main differences consist that C. melanoxeros presents carpophores larger folds more marked in the hymenium, which is more dark-colored
ro (gray-violet) and, above all, because the rubbing or blacken meat aging, mainly on the edge, such and as seen in the photograph. Microscopically also be differentiated easily because C. ianthinoxanthus presents spore longer, up to 12 microns.

Could you give me more details about the confusion between C. ianthinoxanthus and C. malanoxerus?
