Pyrenomycete

Hi
I found this ascomycete growing on dry herbaceous stems.
With 3-5 locules in each is stroma.
Spores hyaline. Some with appendages at both ends.
Asci with apical apparatus visible in water, IKI -. 60-65 x 6-8um.

I do not know what species it is, perhaps Phyllachora sp?
I would appreciate any help.


A greeting and thanks.
Susana?

Re : Pyrenomycete
Hi Susanna,
It's a Mazzantia species.
Could your herbaceous stem be Solidago ? If yes, it could be M. biennis.

Re : Pyrenomycete
Hi Alain,
Thank you for identifying the genre.
I do not know who is the host. I found some dried stems hardly identifiable.
I have no literature of the genre. Is there a key? or the species depends on the host?.
I have seen in the database that is very similar to M.gallii. I know in the area is common Gallium aparine. Could it be?
Thank you very much, greetings
Susana?

Hi Susana,

there are 4 species described in MONOD 1983. I can send you a copy of these descriptions via email.

Re : Pyrenomycete
Possibilities : 
M. galii on Galium / 8-10 x 2,5-3 µm
M. brunaudiana on umbellifers / 9-10 x 4 µm
M. napelii on Aconitum napellus / 11-14 x 3-4 µm
M. biennis on Solidago juncea / 7,5-11 x 3-4,5 µm
M. borealis on Anemone, Tanacetum / 6,5-10 x 3-5 µm
Perhaps some are synonymous (it's my opinion). But know the host is important.
For the yours, M. napellii is the most probable.
