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.

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

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.

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 ...
Best regards, Lothar
