Need help for this specie. I'm sure I have seen it in this forum next year, but not able to find it again.
Host: on decayed wood of Fraxinus.
Macro: many apo. short stipited, hymenium yellow to grey-green, Excipulum grey-green with many short yellow hairs. Base grey-green to black.
Micro :
spores 7-8,4x3,8-4,1 um, without guttules. Q=1,8-2,1.
Ascus 60-80x5-6 um, with croziers, IKI+
Paraphyses spindly, rounded at the end, with some guttules, 1-2 um widh, 70 to 100 um long.
Hairs brown, septate, more then 4 celled, 100-120x5-6 um. Becomes green With Lugol.
Have you got an idea ?
Yannick

Re:asco sp.
Oui, voilà ! C'est ça.
Je m'étais arrêté à Lachnum cerinus/a sans trouver ce genre.
Merci Guy !

Re:asco sp.
Yes, je pense la même. But N. cerina MUST be simple septate, and I feel your image does not show a crozier. You can test with KOH: usually this species yields a purplish dye from the hairs into the medium.

Re:asco sp.
I'm going to try KOH.
What does it mean : "simple septate" ?

Re:asco sp.
Hi Yannick,
simple septate means without croziers, and the purplish dye comes from the excipulum.

Re:asco sp.
I noted the purplish dye from the hairs (similar as in Perrotia flammea), but maybe it comes also from the excipulum. This dye is strongest at the moment when the KOH comes in contact with the fungus, later it rapidly dilutes. If you simply mount a fragment in KOH you will not see it. Therefore either put an apo under the bino in a drop of KOH during which you look what happens, or you add KOH to a water mount and look what happens as soon as the KOH reaches the fungus.
