Strange fungus on dung

Nicolas VAN VOOREN, 20-12-2020 09:30

Here is a strange fungus growing on old dungs. Macrophotos sent by a colleague, so I don't have any information about microscopical characters.
It looks slightly like Anthina flammea but I never saw the latter with such a colour and on this substrate.
Any idea?

Re : Strange fungus on dung

Re-bonjour Nicolas,

Cela me fait penser à Laetisaria fuciformis, anamorphe d'une corticiale qui serait toxique pour le bétail et je vois que ça pousse sur des excréments de bétail qui serait le vecteur de la dissémination du champignon.

Voici une de mes photos.

Re : Strange fungus on dung

Merci Bernard, ça me semble être une hypothèse plausible. Voyons si d'autres personnes partagent cet avis.

Re : Strange fungus on dung

Hello Nicolas and Bernard,
Bernards fungus is L. fuciformis without doubt, a fungus paratizing on grass (red grass disease). I do not thing the fungus of Nicolas is the same.
Best regards, Lothar

Hi,

here is an occurance on goose dung from Iceland:

Dung can contain a lot of grass...

Re : Strange fungus on dung

Hi,

last week I also had a request, which pink mushroom ("club") grows on mouse dung.The macro photos are identical to those of Nicolas. I had the impression that the mushrooms did not grow on manure in general, but were only somewhat obstructed. They're going to do a microscopic examination of the fungus. My first thought was also Laetisaria fuciformis, which I know well.

Peter.
