Marthamycetales? - from Portugal

... on twig in the air at standing Ceratonia siliqua. Only seen after watering (the twig taken because of other fungus). The spores measure about 40-60/6-7 µm and have 8-12 septa - often one end is thicker than the other one which is tapering to an acute(r) end.
The hymenium reacts amyloid as a whole (exudate?) - the rest of the fungus is dextrinoid.
Does somebody have a hint?
Best regards, Lothar

Re : Marthamycetales? - from Portugal
I think this is Ostropales. I was thinking about Stictis conotremoides Sherwood. Perhaps you can try looking at that? I collected this once in Canada. Do you know about these papers on "optional lichenization" by Mats Wedin? He was writing about Conotrema urceolatum (= Stictis urceolata) which is a lichen, but can develop as a saprobic fungus (no thallus) depending on environmental factors. I wonder if your fungus is not a saprobic state of Stictis urceolata.

Re : Marthamycetales? - from Portugal
Hello Jason,
thank you very much for your contribution and the species proposal(s).
I will try at home to fiind out more (am on the journey back).
I then will try to find Wedins paper.
Best regads, Lothar

Re : Marthamycetales? - from Portugal
Here is a link to the protologue of Stictis conotremoides. Note that I don't think Wedin mentions this species but I suspect this is related to the issue.

Re : Marthamycetales? - from Portugal
Hello Jason,
sorry for the late reply - but we jaust came back home from our journey yesterday.
Thank you very much for the Wecin paper and the link.
Unfortunately, the link seems not to work properly (at least in the moment - I will try again later).
The site is testing that I am not a bot - but as it seems not successfully. It begins again and again to test ...

Re : Marthamycetales? - from Portugal
Well, that's a pain in the butt. That's happened to me once before but it cleared up. I'd try it again. In the meantime, here's screenshots of the description. I think there might be differences between yours and this description but maybe close? Do you think yours could be a Stictis?

Re : Marthamycetales? - from Portugal
thank you very much Jason!
I will write again when I find time again to go to the subject.
In the moment, there are lots of things to do first.
Yours, Lothar

Re : Marthamycetales? - from Portugal
Hello Jason,
I just took a look at the publications you sent me - thanks again for this!
And yes: Stictis conotremoides (urceolatum) seems to be a very good hint, close to my find.
What makes me hesitate is ecology - and I do not mean the problem of lichenization and saprotrophy.
No - Wedins collections are from Northern Norway, and Sherwoods from Arctic Canada.
Do you know of Stictis urceolata-collections from the Mediterranean climate zone?
I could still re-examine a part of the specimen. What do you think could I still do to contribute to more clarification?
Yours, Lothar

Re : Marthamycetales? - from Portugal
Got it. Yes, Mediterranean... so maybe not Stictis urceolata. Maybe when you reexamine the specimen, confirm that it's Stictis? Do you have Sherwood's various papers dealing with Stictis and Schizoxylon species? The dark blue-gray disc is striking.

Re : Marthamycetales? - from Portugal
After some search I find a specimen from Taiwan, on Miscanthus, that could have a similarly warm climate. It seems to be sequenced.
https://asianjournalofmycology.org/pdf/AJOM_3_1_3.pdf
In the text the spores fit well, and the macrofotos do this, too. But in the table of fotos there are spores of a normal Stictis (long and thin). A mistake in the paper ...???
I think Stictis urceolata ist a good hint still.
What should be the proof for a Stictis?
I will try to do a section of the apothecium, and if I get better pcitures, I will show.

Re : Marthamycetales? - from Portugal
I'll look at the books I have at home and get back to you. In the meantime, I think the big distinction for Stictis vs other genera like Schizoxylon is that the hymenium is always separated from the inner surface of the "margin" when the specimen is dry. So, looking at an apothecium through your dissecting scope, there should be a space between the hymenium and the margin. I hope this is clear. Do you have Sherwood's 1977 monograph in Mycotaxon? It's that link to BHL I sent you earlier. I hope that it works for you this time! There's illustrations of what I'm talking about in the Introduction. Definitely try to make a section of an apo.

Re : Marthamycetales? - from Portugal
Yes, the spores in the image in that paper are quite narrow. They don't look anything like 3-4 um wide like they wrote in the description.
