Hymenoscyphus calycinoides ?
Nicolas VAN VOOREN, 26-08-2012 20:46
Nicolas VAN VOORENBonjour.
Trouvé dans un ruisseau, sur bois mort à demi-immergé, une miniature de Cudoniella clavus, mais avec des caractères différents :
Apothécies de 1-2 mm de diamètre, stipe long de 2-4 mm, entièrement blanchâtre, devenant ochracé avec l'âge
Excipulum ectal de textura angularis/subglobulosa ; excipulum médullaire de textura intricata, partiellement gélifié
Asques avec crochet, à anneau apical distinctement IKI+ (bb), type Hymenoscyphus
Paraphyses non guttulées, Ø 3-4 µm
Spores (13) 14-19 (20) x 4.5-6 µm, subfusoïdes, avec 1 cloison médiane, contenant quelques guttules.

L'espèce la plus proche me semble être Hymenoscyphus "calycinoides" présente sur le DVD de Zotto.

Hi Nicolas

Are these black dots inside the cells? ;-)

To become more sure about this you need to search for a living ascus and to look if the spores are septate within or not. The paraphyses look alive and do not contain the VBs that calycinoides has.

I also see a 3-septate spore on your pic which is certainly an overmature one.

In any case, I have not an idea what you have.

Re : Hymenoscyphus calycinoides ?
Spores are septate in asci. You're right also concerning the overmature spores, they can be 2 or 3-septate.

Re : Hymenoscyphus calycinoides ?
But did you see living asci? It does not help if you saw them in dead asci. Then they may still be ejected when non-septate. You have no photo of the asci?

So what can we conclude about your fungus? Can you say if the substrate is coniferous or not?

The collection comes from decideous wood.
I'll try to make another collection to verify all the characters, including the spores in living asci.
