Bonjour à tous,Voici quelque chose dont je ne sais même pas s'il s'agit ou non d'un ascomycète !?
Sur cône pourri d'épicéa dans le drain d'une pessière.
Observations dans l'eau et dans le lugol. On voit comme des petites ruches en paille tressée…
Merci d'avance pour vos pistes !

Re : Sur cône pourri d'épicéa
Dear Bernard,
the conidia look as of Helicoon sp. Are you sure they derive from these minute apothecioid looking fruitbodies?

Re : Sur cône pourri d'épicéa
Good evening Martin,
Thank you very much for your message!
I just revisit this little mushroom and I find the same microscopy. I did not know the genus Helicoon and it's true that it looks like it quite microscopy !
Is ecology would know the species ?

Please note that the picture "picture 7" was taken in the sample Hamacantoscypha uncipila!

Re : Sur cône pourri d'épicéa
Hi Bernard,
the conidia of Helicoon are born from single or branched conidiophores, it is a Hyphomycete. No fruitbodies in a broader sense are expected here. I consider these as a contamination or a parasite on your tiny apothecia. Did you try to squash of them slightly in a mount, so they are still visible in their shape?
Is picture 7 again with Lugol or is this conidium naturally brown?
By the way: in the lower Part of pic 7 are maybe the asci of the white apothecia visible....

Martin

Re : Sur cône pourri d'épicéa
It is Helicodendron giganteum, for which a Mollisia teleomorph was described. A common aeroaquatic fungus. Kind regards Hermann

Re : Sur cône pourri d'épicéa
Hi Martin,
Thank you for the informations !
I have again taken small "apothecia" on spruce cone and I observed in the water without squashing them and confirm that they are the spiral conidia. The picture 7 was made in water, since the brown conidie would probably mature.
Here are 4 pictures made in water and without squashing.

I do not know anything about this genus ! That discovery for me!

Re : Sur cône pourri d'épicéa
Thank you Hermann for clarifying this! Indeed a good match!
But still we don't know the identity of Bernards teleomorph ascomycete.
Bernard, please try a squash with asci and paraphyses. Don't let you be diverted by the big conidia... ;-)

Re : Sur cône pourri d'épicéa
The only ascomycete on this spruce cone is Hamatocantoscypha uncipila. I have presented today this species in the discussion 'Asco sur cône pourri d'épicéa'. I have not seen Mollisia on this cone.

Re : Sur cône pourri d'épicéa
Hi Bernard,
but this H. uncipila is a yellow species. The one presented in this thread is white to translucent... Not necessarily a Molisia by beeing the possible teleomorph of the Helicodendron.

Re : Sur cône pourri d'épicéa
Hi Martin,
I'll watch the cone again, but actually I saw on a resin flow another white ascomycete. I will give news tonight.

Re : Sur cône pourri d'épicéa
Hi Martin and Hermann,
Here are micro and macro pictures of another fungus that grew on the same cone (with Hamatocanthoscypha uncipila and Helicodendron giganteum).
Conidia are globose and uniguttulated : 2,5 mu diameter
Are there a possible relationship with Helicodendron giganteum or not ?

Re : Sur cône pourri d'épicéa
Dear Bernard,
this is just another anamorphous fungus. No idea which one.
But you did show in picture seven a glimpse in a squash of the first one. I marked the asci with a red arrow. Are those apos gone?

Dear Martin,
No I still have apothecia of Hamatocanthoscypha uncipula which is drawn the picture 7. Do you want I observe apothecia of this species again ?

Oh, this is Helicodendron giganteum. I had it too together with Hamatocanthoscypha uncipila the last week.

Re : Sur cône pourri d'épicéa
Hi Björn,
Thank you for your message and congratulations on your beautiful photos!
Do you think Helicodendron giganteum can be an imperfect form of Hamatocanthoscypha uncipila or the presence of these two species on the same cone is it coincidence?
Best regards,
Bernard
