Dear Ismael
your image are a bit small, and I am not even sure whether you are dealing perhaps with a pyrenomycete. Do you have a macrophoto? Did you test IKI for the ascus apex?

Re:eupropolella?
your camera is obviouly not suited for macro, sorry. Maybe you can put a leaf uner the microscope at the lowest magnification and lighten with a lamp from above?
These asci lok alive, but the spores reach down to the base. Looks a bit like a pyreno. I hope that Alain is also looking here.

Re:eupropolella?
Dear Ismael,
I think your fungus is maybe Bionectria coronata or Pseudonectria rousseliana.
Hairs around the ostiolar region (on your picture) resemble to these species.
Could you please to show us a perithecium observed in drop of water without cover glass at low magnification?

Re:eupropolella?
well on other leaves it does have the pink of Volutella. The spores of pseudonectria are, in my view, to small and whynot mention the many guttulae?

Re:eupropolella?
you should have to test reaction in KOH and lactic acid.
B. coronata not changing colour in KOH or lactic acid.
P. rousseliana not changing colour in KOH but becomming yellow in lactic acid.

Re:eupropolella?
right lactic acid, i dont think i have that. In KOH no reactions. Can you buy lactic acid under what name? I still feel P. rousseliana is not the one....Because well i dont know :-/ because of the guttalae i suppose, ellis doesnt mention it, and the length seems to be longer

I show you photos of P. rousseliana. Perhaps do you recognize It ?
He has orange to greenish colour.

Re:eupropolella?
And you can see setae on ascomata.
More, Bionectria coronata has uniseptate ascospores when Pseudonectria has nonseptate ascospores.

Re:eupropolella?
hi there, unfortunately i cannot find those forms. What was the magnification you used? The ones i've got seem to be imbedded in the leave, the ones you are showing are on the leave yes? Best picture i can get is the next one, i think they begin a bit pinkish and end up black. Also the spore you are showing are very different from mine. Yourse are not full with droplets mine are

If your recolt is copious, I would like to see a piece. Would you be OK ?

Re:eupropolella?
Hello Ismael, (hello Christian),
I've studied your recolt (good material) and I recognize Hyponectria buxi.
I'm happy because I've never studied it before.
Perithecias are well immersed so it couldn't be Bionectria or Pseudonectria.
One Hyponectria has been synonymized with Eupropolella (=Polystigma volkartianum). So your idea was not a bad idea.

Hi Alain,
Who are the authors for this species, Mycobank thinks it is a anamorphic fungus,
can you give any clearence to this case so i can assist Ismaël to put this species on the Netherlands fungi flora list
thanks in advance

Hi Christian,
Hopefully someone solves it someday, this is a more difficult problem as all Lachnum species belonging to Tricholomataceae a couple of years ago in index fungorum :)
