Hello Edvin,
whatever this is - no apothecia.
Oddly enough: there is no Octospora known from Ulota by now (as far as I know).
Best regards, Lothar




Sorry, I was too fast - and did not see the foto of the ascus first - and thought the second fotos (the very long spores, which more likely are conidia) would be the spores of the fungus.
So - this could be apothecia. Maybe of a species of Octosporella or something similar.
Best, Lothar

I also do not believe in a myxo - if there is a bet between you I go with Edvin.
Best, Lothar





I wonder if this collection could be related to Belonium coroniforme (in Zotto's folder under Belonioscyphella here: https://drive.google.com/drive/u/0/folders/0B5SeyOEkxxZhaG11dlBYTDZtREk ). The spore shape and contents and apothecium structure look similar to me, however spore size is different and no septa there.

For the iodine reaction I think one ascus shows the red very well. Interesting would be to try a KOH-pretreatment. The Congo might disturb a bit the test, mut mot much. After adding 2-5% KOH for some seconds and removal of the KOH with water, add again IKI or MLZ and, apart from the blue apical ring you should see a distinctly light blue hymenium as figured by Raul.
Indeed Rehm's remark of inamyloid asci is surprising because he used IKI, not MLZ, which was not in use at that time, and he described the red (hemiamyloid) reaction as violet when he saw it.
A DNA result would be great of course.

is it possible to access that google disc resource for anyone, or is it restricted?

do you get a problem when clicking on the link?
You can also try via my homepage, but maybe the same will happen.

Martin, the type label is interesting, I am surprised to see large globose oil drops which look like in a living spore! In Raul's photos I only see many small droplets. These large drops Rehm did not mention, instead he described the dead spores with their obvious septa.

But now I realized in your living spore the large drops just as Rehm had drawn them!







Belonioscyphella hypnorum is very difficult to put in a family. There is ITS, LSU and Ef1 in GenBank by Z. Egertova. Zuzana, did you compare your LSU? What is next in Blast?

ich bin neu hier im Forum. Im speziellen intressiert mich die Diskussion um B. coroniforme und um seine Trägermoose. Darf ich fragen: Auf Grund welcher relevanten Merkmale wurde diese Probe als Ulota crispa bestimmt? Lagen gut ausgebildete Sporophyten vor?
Besten Dank!
Wenn es erwünscht ist, kann ein Bild mit dem inneren Peristom der 4 Ulota-Arten die auf den ersten Blick verwechselt werden können, zeigen.
B. coroniforme auf U. crispa ist sehr interessant. Die Funde von B. coroniforme in der Schweiz sind bis jetz alle auf Orthotrichum pallens gefunden worden.



A just found the same fungus as you in the Pyrenees, also on Ulota apex. Have you finaly concluded with the help of colleagues and/or DNA analysis ?
If so, I would be interested in the conclusion.Thank you very much.
