Bonjour à tous, Marcel LECOMTE président de L'A
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.
I don't know a good genus for my collection.
What's your opinion
Many thanks in advance
Enrique
looks quite similar to Pseudotrichia viburnicola.
Best wishes,
Gernot
It seems to be clear!!
Many thanks
Enrique
this one should be new to Spain.
Best regards
Martin
I have send you by e-mail the coordinates of my finding

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 helix
Enrique
thanks for the data!
It turns out again that Pseudotrichia viburnicula is not very picky in choosing the host...
Best regards
Martin
