Bonjour à tous.Je m'interroge sur un asco qui tourne peut-être autour de Bisporella subpallida, bien que la couleur ne soit pas la même. Pourriez-vous me donner un avis ?
Description :
Macro :
Fructifications cupuliformes, crème à jaunâtre pâle, diamètre 1 mm, excipulum concolore à l'hymenium, marge blanchâtre.
Micro :
Spores elliptiques et parfois en "pépin" de raisin (il y a un mot pour cette forme ?), hyalines, 5-5,8x3-3,2 um.
Paraphyses cylindriques 60-70x2 um, 2 cloisons, nombreuses guttules dans le dernier article.
Asque IKI+, boucles +, spores unisériées, 70-80x4-5 um.

Hi Yannick
I am sure you have B subpallida. The guttulate paraphyses are characteristic. The spores are a bit wide and short, perhaps anomalous, but I find them rather variable, especially in length (upt 9.5 µm).

Pour Bisporella subpallida, j'avais observé, dans le Melzer (j'utilisais pas le lugol à cette époque-là !) une réaction bleu ciel de certaines cellules de l'excipulum.

Re:Bisporella subpallida
Thank's a lot.
What do you think about color? Isn't it too light ? Isn't B. subpallida yellow-ochre ?

Re:Bisporella subpallida
B. subpallida varies from very pale cream to light yellow. I have one macro image only (not even by myself, it's by Bernd Mühler from Chemnitz I think. I have not examined it but it seems o.k.). I also repeatedly observed a blue iodine reaction at the base of the apothecium (in section), in IKI as in MLZ.
