Possible Ascodesmis sphaerospora?

Dear colleagues,Recently I found this specie of Ascodesmis Tiegh.. I believe strongly in the case of A. sphaerospora, including the steps of spores, and asci paráfises are identical to those mentioned in the literature. However, as you can see, these are partially spherical spores (some are entirely), and its ornamentation appears a network crosslinked with few spines or warts. Only the form of spores changes a bit and brings me to doubt about the species. The disgust is 8-spored, clavate, perithecia small (0.5 mm), colorless and yellow at maturity when young. Scattered to gregarious. What do you think of that? Agree that it is even Ascodesmis sphaerospora??
Sincerely,?
Francisco Calaça

Hello Francisco.
It is often difficult to differentiate species Ascodemis. A number of spores seem rather ellipsoids. Measuring many spores may be able you better orient you.?

Re : Possible Ascodesmis sphaerospora?
Bonjour,
D'accord avec Michel, il faut la taille des spores.
Les images me font plus penser à A. nana car, effectivement, elles ne semblent pas rondes !
Amicalement,
Alain

Hello,
the average of the spores is between 10-14 microns. The spores Ascodesmis nanadont reach 14 microns, so I doubt this, friends ...

Re : Possible Ascodesmis sphaerospora?
Actual length of spores corresponds to A.sphaerospora, but should also measure the width to compare with A.microscopica?.

Re : Possible Ascodesmis sphaerospora?
Dear Francisco,
please compare your species with Ascodesmis nigricans Tiegh.!
For me it's clearly this species.
Look also at the Le Gal - Paper
Best wishes
Norbert

Dear Norbert,
the resemblance is too big, I'll do it, confirming, you say! Thanks for your support!?

Re : Possible Ascodesmis sphaerospora?
Interesting!
When I saw the spores, I thought, that there are some nivicolous myxomycetes spores among the specimen. Then I noticed, that they were inside the asci.
For instance Lamproderma cristatum and some Meridermas have spores, that resembles those. Even the size is something like that. As known, myxomycetes "eat" bacteria and fungi.
Just got a funny feeling of an union of myxomycetes and ascomycetes, That can't be possible or what?
Just wondering: Marja

Re : Possible Ascodesmis sphaerospora?
Yes, Marja, my girlfriend studying Myxomycetes, and she eventually finds spores much like these! I also think this dubious symbiosis between ascomycetes and Myxomycetes ...
Cumpliments!?

Re : Possible Ascodesmis sphaerospora?
Dear Francisco,
so you are getting a feeling, that this is not a primitive form of an ascomycetes but more like something new developing ;)
I have studied more myxomycetes than ascomycetes lately. Got still hundreds of specimens from last year to be determined...
Would like to change opinions with your girlfriend: Marja

Re : Possible Ascodesmis sphaerospora?
Dear Marja,
you should have seen the Myxomycetes she meets! She works in a humid chamber with litter, this litter is from the Brazilian Cerrado. Species are beautiful, and some with spores similar to those of Ascodesmis, other even more beautiful. She found a Diachea leucopodia I'm fascinated! Bela! If you want to contact her, let me know by this email, which is my: calacafjs@gmail.com step and then you touch it.
Hugs mycological!?
