Nectriaceae?

Est-ce que quelqu'un peut m'aider à déterminer cet asco, qui selon moi appartient au genre Nectriaceae.Récolté samedi passé sur des tiges mortes de Typha latifolia.
Ascomata rond, couleur jaune-orange, poussant au-dessus du substrat, dimension du diamètre 0,20-0,23mm
Asci 70-85 x 9 - 12 µm.
Spores 17-24 x 4-5 µm, cloisonnées 3 fois.

Bonjour Piet,
Un Hydropisphaera certainement, donc un Bionectriaceae (tester la non réaction à KOH).
Probablement Hydropisphaera erubescens. Les spores seraient-elles striées ?

Re:Nectriaceae?
Mais je m'interroge sur l'habitat, H. erubescens étant régulièrement observé sur feuille de houx.
Si un spécialiste pouvait prendre le relai...

Re:Nectriaceae?
Good Morning Piet!
I agree with Alain, your fungus is most likely Hydropisphaera erubescens. We've had it on a wide range of substrata, including Holly (Ilex) in France, and geographic locations (as far away as New Zealand). An interesting, and distinctive, feature of this species is the presence of orange globules in crush mounts in water.

Re:Nectriaceae?
Merci beaucoup Alain pour votre réponse trés rapide. La réaction au KOH est négative et les spores sont lissent.
Also many thanks to Gary for his confirmation and explanation.
