Bonsoir à tous,

Je pense ne pas me tromper mais comme je n'ai pas de clé des Encoelia, je souhaiterais confirmation. Sur branchette morte de Salix gr. cinerea en bordure d'étang

a) poils septés, lancéolés à l'extrémité
b) spores ellipsoïdes, subfusiformes à phaséoliformes, microguttulées : 7,5-9x3-4

Bonsoir Bernard,
Pas de problème, ça correspond tout à fait à mes récoltes du Maraais de Saône.
Il y avait du monde !

Re : Encoelia fimbriata sur Salix gr. cinerea ?

Hi Bernard

tres tres bon! Surely you are right. Such lanceolate paraphyses appear a bit untypical, maybe Guy can comment about this. And spores up to 4 µm wide appear to me also quite exceptional. You don't have a consistent magnification so that it would be possible to put a scale in them?

Re : Encoelia fimbriata sur Salix gr. cinerea ?

Bonsoir Gilbert et Michel,

Merci pour votre confirmation ! En le cherchant bien, j'en ai trouvé quelques stations dans la région.

Amitiés,

Bernard

Re : Encoelia fimbriata sur Salix gr. cinerea ?

Good evening Zotto,

Thank you for your message !

As I mentioned, I measured blindly not knowing what I should see or measure.

I'll watch again the hairs and measure the spores again to get a more objective idea.

Note that I can not put a scale on my photos. If you would like me to check something else, do not hesitate to tell me.

Best regards,

Bernard

Re : Encoelia fimbriata sur Salix gr. cinerea ?

My feeling is that your photos are all at the same magnification, or am I wrong? Do you use a zoom? maybe I asked you this already.

Re : Encoelia fimbriata sur Salix gr. cinerea ?

I work with a camera ToupCam for a month and a half. Most of the time I shoot at 100x and then after I rework the picture framing when needed. I also changes the size of the image in Photoshop and when I put the photos into different contact sheet, it is true that different pictures of the same elements may be at different scales.

Re : Encoelia fimbriata sur Salix gr. cinerea ?

Yes, o.k., but when you take your original photos taken at 1000x I think you could build a scale for them. It is very often fortunate to enable measuring elements from a scale. like here. I would also like to know the size of your tirgescent ascus of E. fimbriata.

simply take a photo of a calibration slide under oil immersion, then you have the scale.

Bernard CLESSE, 22-12-2015 22:58

Bernard CLESSE

Re : Encoelia fimbriata sur Salix gr. cinerea ?

Actually, I don't have calibration slide but I'll find out.

For the photo of turgescent asci, like this one for example ? I can make a few measures.

Re : Encoelia fimbriata sur Salix gr. cinerea ?

Bonjour,
Très belle récolte, j'ignorais l'existence de cette espèce alors j'ai cherché dans ma documentation : Ellis, Grelet, Medardi, ... E.fimbriata n'y est nulle part mentionnée.
Dans quel ouvrage y a-t-il une description de cette espèce ?
Existe-t-il une clé des Encoelia dans laquelle cette espèce est indiquée ?
Merci d'avance.
Michel

Please consider also Guy Marson's article in Beitr. Kennt. Pilze III: 465-484 (1987).

Bernard, Kadri Pärtel is interested to obtain a portion of your collection. She wants to complete sequencing which she started with an old sample already. Would that be possible?

If you agree I will send you her address by mail. Did you notice any fungal association (this was also a question by Kadri)? The branch was probably still attached? Is it a swamp/bog there at the lake?

Re : Encoelia fimbriata sur Salix gr. cinerea ?

Good evening Zotto,

Yes, of course, you can give me the Kadri Pärtel address !

I have not found apparent fungal association. Indeed, the willow (Salix cf. cinerea) was still attached to the tree. This is a swampy willow grove bordering a large lake .. You will see on Google Earth where I pointed discovery.

Best regards,

Bernard

I see a mistake in my previous message !

Read : "the branch was still attached to the tree (Salix cf. cinerea)"
