Bonjour,je serais heureux d'avoir votre avis sur c
Hello again
These nice, gregarious, small (0-7-1 mm), ostiolate, pseudothecia with conspicuous orange yellow neck that turns purple in KOH, grow under a dense, byssoid, ochracous subiculum on indeterminate wet hardwood in riversides.
Asci bitunicate, 8-spored. Pseudoparaphyses present. Ascospores 55-98 x 12-17, 7-septate, the fourth cell wider. Walls minutely verruculose in Melzer.Â
I don't know a good genus for my collection.
What's your opinion
Many thanks in advance
Enrique    Â
looks quite similar to Pseudotrichia viburnicola.
Best wishes,
Gernot
It seems to be clear!!

Je suis d'accord avec Gernot. La représentation et description de ce spécimen(réaction KOH ,mensurations et cloisonnement des spores et asques bituniqués) convient
parfaitement pour Pseudotrichia viburnicola. On peu le trouver sur une large gamme
d'hôtes,sauf sans doute les résineux
Amicalement,
Paul LEROY
L'hote de mon recolte est Hedera helixÂ

I have another collection of Pseudotrichia viburnicola on Wisteria sp. branches at 2 m over the ground.
The data of this collection are:
Oviedo, jardines del Hospital Covadonga (Asturias) Spain, 30-VII-2013, on Wisteria, ERD-5948.
thanks for the data!
It turns out again that Pseudotrichia viburnicula is not very picky in choosing the host...
Best regards
Martin
