Bonsoir.
Comment qualifier ces spores ?
Simplement fusiformes ? Peut-on rajouter scutelloïdes ?
Merci d'avance.

Re : Spores description
Hi Yannick
You mean scutuloid. No this is homopolar or almost so, i see no clear scutuloid shape.
I guess Hymenoscyphus macroguttatus?

Re : Spores description
Thank's Zotto.
Well, for the specie I don't know, I was spoken about it with JPP.
Here is it's description :
Found on Carpinus decorticated wood in an empty pond.
Not reddening when hurted.
Asques with croziers, IKI+
Paraphyses with small guttules, filiforms, 2-3um wide.
Spores fusiform 18,3-20,7x4,3-5,3, Q=3,8-4,7
Paraphyses with small guttules, filiforms, 2-3um wide.
Spores fusiform 18,3-20,7x4,3-5,3, Q=3,8-4,7
In B. Declerc Key, I think I must go to table number 7 : Phaeohelotium group.
After, It's difficult...

Re : Spores description
Ah, then it should be P. epiphyllum.

Re : Spores description
Well, I'am not sure :
1/ apo never reddening when dammaged;
2/ found on Carpinus decorticated and wet wood. P. epiphyllum come on wood ?

Re : Spores description
Surely it comes also on wood. I should see the small guttules in the living paraphyses. Alternative is P. monticola.

Re : Spores description
These both species have been sequeced too ?

Re : Spores description
Yes indeed, and they stand very apart from each other so that some think they should be placed in different genera.

Re : Spores description
Paraphyses with guttules, unfortunately in "rouge congo".

Re : Spores description
Ah o.k. this leaves me undecided, I had repeatedly problems to separate the two species and finally arrived at the Vb content of paraphyses, but even there it seems variable to some extent.

Re : Spores description
Ok, so let's wait for ITS. I will contact you then.

Re : Spores description
salut Yannick,
je qualifierais tes spores de fusiformes-inequilatérales.
