HiFound this one on a twig of Abies in Sweden.
Apothecia paler when wet.
Apothecia react K+ yellow floating substance.
Asci 8, 100-130 x 12-14, IKI -
Spores at fist aseptate finaly 1 septate, 16-19 x 8-9.5
paraphyses a litle wider at top, septate
Anyone knows it?

                Re : Claussenomyces? on twig of Abies
                Although the asci are narrower and the spores uniseriate, this sounds to me like Patinella punctiformis. I have it actually in Tympanidaceae, folder Pragmopora-like.
This is among my wishes for a sequence, I studied the type but never saw a further collection, except for one on Quercus.
Could you please measure the apo diameter? I am not sure with my 0.3-0.7 mm. Rehm measured 0.2-0.4 mm.

                Dear Zotto,
Amazing as usual!
Its a good collection with many apothecia.
Regarding sequnce it i will try to convince my friend to do it.
I will measure some apothecia and take pictures tomorrow.
All the best,
Robin

                Hello, this should be Pseudotryblidium neesii. Not that rare on Abies bark. Patinella punctiformis f. quercina is probably related indeed, I've seen it 2 times on Quercus bark. Not sure about Patinella punctiformis.

                Re : Claussenomyces? on twig of Abies
                Good hint, Adam! I overlooked the KOH-reaction mentioned by Robin. That species I have in Dermateceae.
For the type of Patinella punctiformis on Picea bark I already had the note: "Similar to Pseudotryblidium neesii, but without ionomidotic reaction".
For P. neesii exist sequences in GenBank, so no need for this one.

                Dear Adam and Zotto,
Thank you!
I did cut some moore apothecia, after some time i did found 2-3 septate spores in asci.
The asci is weak react brownish red in K.
I can not se the red/ purpurle reaktion in K.
In my it become a brown floting lequid.
Maybe this is okey? as it is a new species to Sweden.

                This is distinctly a ionomidotic reaction. The asci and spores are in KOH +  iodine?  I see no reaction of either of them.

                Re : Claussenomyces? on twig of Abies
                Ah, you mean the ascoplasma (and sporoplasma) reacts in a similar colour as the pigment extruding from the excipulum. That is right, although hyaline when alive such coloured plasma often occurs in dead cells, I am not sure if KOH is necessary for that.
