Bonjour,
Ceci est apparemment: Pseudotrichia viburnicola (P.Crouan & H. Crouan) Rossman

Hi Elsa,
pictures are blurred. But could it be Pseudotrichia viburnicola? Better pictures available?
What do other colleagues think, familiar with this fungus?
Portugal would be no problem for the distribution of this omnivorous species, au contraire.

Martin

Re : On Magnolia grandiflora bark
Well, Paul had the same idea. Would you mind to send me the collection data (date and site)? I am recording all informations regarding this species. This would be a "first" to Portugal.

Re : On Magnolia grandiflora bark
Hi, thank you both, Paul and Martin,
After reading something about Pseudotrichia viburnicola, I think you're right!
I have a very small sample, and few pseudothecia, so I didn't want to waste it, before I post this message. I can repeat micro now, but the fungus could be old, as I didn't find any asci on this first micro.
Location and Date: Riba d'Ave (Vila Nova de Famalicão); 21/07/2017
Thank you guys, you're amazing :)

Elsa

Re : On Magnolia grandiflora bark
Cette photo est peu différente de la précédente et je maintiens: Pseudotrichia viburnicola
Pour vérification supplémentaire, prendre un peu de la substance jaune-orangé présente à l'ostiole et la mettre dans une solution aqueuse d'acide lactique. La réaction doit-être pourpre-rosâtre.
Cette espèce n'est pas inféodée à un hôte strict, je l'ai trouvée sur différents supports ligneux: arbres, arbustes, arbrisseaux.

Re : On Magnolia grandiflora bark
Dear Paul,
Thank you for your suggestion and opinion. I do not have lactic acid. On last photo I show a change of colour to purple after NaOH (I do not have KOH), and that's all I can do.

Elsa
