Mollisia???
Luc Bailly, 23-06-2009 21:13
Luc BaillySur bois très pourri, probablement Corylus avellana, dans une chênaie-charmaie à Corylus et Acer campestre, très sombre.

Apothécies épaisses, trapues, molles, d'un olivâtre pâle, se teintant de rosâtre localement, furfuracées, sessiles. Excipulum quasi hyalin: voir photo. Asques 8-sp., 49-65 x 5.5-7, IKI B (plus visible dans le Meltzer), spores bisériées. Crochets présents. Paraphyses septées, bifides ou un peu branchues (photo), -> x2 µ; KOH -
Spores parfois un peu courbées, hyalines, 1-septées (mais paraissant non septées tant qu'elles sont dans l'asque), huile = 1(2), 10-13 x 2.5-3 µ.

Une idée?

Vue à la loupe bino.

Asque. Je ne vois pas de septum dans les spores à ce stade.

Calycellina ?

Re:Mollisia???
Needs to see the structure of the excipulum, globulosa, prismatica, porrecta?

It is sufficient to make a photo in surface view but a section is always better. :-)

Re:Mollisia???
Oh well, I forgot to post it. Here it is: it looks globulosa to me.

Re:Mollisia???
Yes but too uncoloured for a Mollisia. Does not look to come from the margin.

Is the margin totally wiothou hairs? Perhaps this is related to Hyaloscypha?

Re:Mollisia???
There are some hairs, more visible in KOH, and they're incrusted. I'll search in that direction.
And yes, it's too uncoloured for a Mollisia, thus my ???

Re:Mollisia???
On the macrophoto I can see the RED reaction od VBs oxydiation. I never seen this in Mollisia, but is often in Calycina/Calycellina or f.ex. Psilachnum.
I think the Apos are "to flaschy", to thick to be Hyaloscypha.

Re:Mollisia???
Yes, the paraphyses have probably VBs which excludes Hyaloscypha.

Re:Mollisia???
It looks somewhat similar to your Calycellina "heterospora", but paraphyses are different.
