Pierre RepellinBonjour à toutes et à tous,Je recherche l'articl
Hi to all:We have collected these small perithecia (or pseudothecia?) up to 0.5 mm in diam. inmersed under the bark of branches of indeterminate hardwood (Acer or Prunus, not Tilia). Ostioles are very nconspicuous.
The spores are very unequally 2-celled. Asci seem to have a very inconspicuous apical apparatus but I'm not sure. They are Melzer negative.
I think in the genus Pseudomassaria but their asci are described as Melzer positive...
What do you think?
Many thanks again
Very nice pictures !
Have you tried Barr's key on the genus Pseudomassaria in Mycologia 56 (6), 1964. Page 843 ?
You can read it on Cyberliber.

Yes. I have read Barr's manuscript but I continue without seeing the light!
Thank you
Enrique

Dans les Hyponectriaceae apiosporés J-, il y a les Apiothyrium, et ce n'est pas cela, et certains Pseudomassaria qui ne collent pas non plus avec celui-ci. C'est pourquoi je m'interrogeais sur l'amyloïdité de cette récolte.
Bonne journée,
Alain
Je suis bien sur que le Melzer est negative et qu'il n-y-a pas des Tilia
J'ai vu á ce link http://www.springerimages.com/Images/RSS/1-10.1007_s13225-011-0104-2-8
des images de P. chondrospora semblebles a mon recolte. A le pied de page ont dit que les asques sont IKI (-).
Avez vous le suivant article?: Hyde, K.D., Frohlich, land Taylor, lE. (1998a). Fungi from palms. XXXVI. Reflections on unitunicate ascomycetes with apiospores. Sydowia 50: 21-80. Peut etre les images sont de ce travail.
Merci de votre aide.
Finally I confirm you that the sustrate is a Tilia platyphyllos single tree situated to a 100 m of the lying branches that I have found.
By the other hand Walter Jaklitsch (pers. com.) thinks my collection fits well with Pseudomassaria chondrospora as Alain was thinking too.
Many thanks to all
Enrique
