Re : Sporormiella Grandispora?
Hi Joop,
yes, this should be S. megalospora, compare with my finding from Austria last year:
Sporormiella megalospora

Re : Sporormiella Grandispora?
Hello Joop and Björn!
Sporesize and germslit conforms better with Sporormiella capybarae.
The spores of Sporormiella grandispora have a parallel germslit and slightly larger spores.
And Sporormiella megalospora has much larger spores.
Norbert

Re : Sporormiella Grandispora?
Thks Björn and Norbert.
Hereby I send you a photo with measurements of each cell Norbert. Maybe this is a better confirmation.
Upper cell conical:
13.74x9.69; 13.08x9.17; 15.31x10.20 (extreme size)
Second cell barrel shaped:
10.55x10.40; 10.75x10.66; 13.16x11.81 (extreme size)
Third cell barrel shaped:
12.49x10.01; 12.46x9.67
Basel cell cylindrical rounded top:
13.99x9.12
Hopefully I can find more photo's of this one.
Do the germ slits also curve near the septum as they do with S. Grandispora Norbert?
In the article of Ahmed & Cain on page 442 about Sporormiella they also say for S. Grandispora that germ slits are usually parallel, occasionally slightly oblique, usually curved next to septum. Cells almost equal in size (in this case they ar not).

Re : Sporormiella Grandispora?
Hello.
In the first photo, where we perceive the asci, they seem to have it as the base ends abruptly. Joop you can get a clearer picture? If this comfirme we would depart from S.capybarae which has asci gradually ending a long walk, and instead seek to S.intermedia.

Re : Sporormiella Grandispora?
Indeed, the asci seem to have an elongated foot, so it must be certainly S.carybarae, but I still find the spores too regular for it.

Re : Sporormiella Grandispora?
OK, but can be seen on your latest photos, some spores with oblique septa, which is not too much to S.capybarae. Maybe Norbert can t give us details of this species that I know little.

This is an interesting problem!
Sorry, but in the moment I don't have enough time for an answer.
I'll write later.

Re : Sporormiella Grandispora?
Hello Michel & Norbert,
Is the shape of the gelatinous sheath a factor for determination?
They often differ in size and form, especially at the septa but they also can be fully cicular I will look up some photos to explain what I mean.
I also include a plhoto where you can see cells of sporormiella opening at the germ slit.

Re : Sporormiella Grandispora?
No, gelatinous envelopes are not an important character in Sporormiella. Looking at your pictures again I wonder if it's the same fungus every time, you're in on? Nevertheless, I stand by my first impression of S.intermedia which can be quite variable. I found some copies of S.intermedia with the base of asci as on your photos, not great either one way or the other.
Michel.

Re : Sporormiella Grandispora?
I think you are right Michel with two different funghi, the first serie is short stalked for the asci. Doveri talks about oblique and sinuous germ slits. Also the spore cells differ too much in length. Documentation notes that the end cells are slightly longer than the middele ones. And here you clearly have different cell lengths.
The other serie does not have short stalks for the asci I am still looking for better photo's that match.
In the first serie the upper cell is conical, the second barrel shaped the third and also the basal end cell cylindrical with a rounded end for the latter.
