Asco on Cornus sanguinea leaves
Enrique Rubio, 11-01-2017 19:03
Enrique RubioHi to everybody
Some time ago my friend M. Tapia, from Navarra (NE of Spain) sent me this strange, gregarious, turbinate, 0.2-0.5 mm in diam., pale grayish-brownish with brownish pruinose hymenium surface by the existence of a brownish, verruculose, granulate, matter that not dissolves in KOH, growing on old leaves of Cornus sanguinea.
The apothecia seems to be glabrous, and many leaves have hyaline or translucent gelatinous conidiomata perhaps belonging to his asexual morph.
The asci are IKI negative, with no croziers and the ascospores do not turn darker. I could see that some paraphyses have VBs that stain in cresyl blue. Excipulum made by prismatical to roundish cells.
Some idea will be wellcome 
Thanks again

What a strange fungud, no idea of a genus!

I have nothing in my database on Cornus leaves with such spore size.

Only the anamorph reminds me of a Pilidium.

Yes. Very strange! It will be for our next life!
Thanks again


PD. If you want, I could send you the images at higher resolution

yes, you can do that!

Hi Enrique,


yes - as Zotto said a very interesting fungus. It reminds me of a Trochila or something like this, but if Zotto is quiet about the genus, I should be quiet, too ....


Could you add the finding-date? It could be interesting for other people to look for this fungus - as Cornus sanguinea is a very widespread host.


Thanks and best regards from Lothar


P.S. Rehm (1896) describes a Naevia carneopallida (Rob.) growing on Cornus sanguinea-leaves. Unfortunately, the data do not fit at all ...

Re : Asco on Cornus sanguinea leaves
I do share Lothar's words and I supposed that Enrique's new discovery is a late one!

The paraphyses reminded me of a Coronellaria species but I think that ENrique you tried CRB and that it does not produce the same reaction .

Bravo anyway (again)

Amitiés
Michel

Hi Michel
Coronellaria is a nice idea, but I am used to see multiguttulate contents in that genus.

Re : Asco on Cornus sanguinea leaves
Hi Michel, Lothar and Zotto
Coronellaria is a nice idea, but the paraphyses are not multiguttulate and lacks an hemiamyloid apical apparatus in the asci. The collection was made on novemebre 17 2016. This collection should be sequenzad, but my study was made with somewhat old specimens. Maybe on next year Mikel will be able to collect newly this fungus.
Thanks to all.
