Claussenomyces?

Josep TorresHello.
Some apothecia sprouting massively on a thin trunk of Laurus nobilis.
Spherical in shape, somewhat flattened, orange when wet and greenish brown when dry. with a diameter of between 0.2 to 0.7 mm.
Octosporic asci, with uncinules at their base and amyloid reaction of their apical apparatus.
Moriform ascospores, poorly septate and with free spore measurements of (12.5) 12.6 - 14.3 (15.6) × (4.2) 4.7 - 5.6 (6) µm.

Based on the data obtained, everything seems to fit with what could be considered Claussenomyces prasinulus, but I already studied Clausennomyces prasinulus last year and the reaction of the apical apparatus to iodine was negative, and I can't find anything more similar than Claussenomyces or Vexillomyces.
Any opinion from you will be well received.
Thank you very much in advance.
Kind regards.

Re : Claussenomyces?
Amyloidity excludes these. Any paraphyses? Why are all elements dead? The excipulum would be important.

Perhaps a Rodwayella?

Re : Claussenomyces?
Thanks Zotto.
The apothecia were not at their best and unfortunately the ascos were dead.
I add a couple of images of the paraphyses, one in water and the other in Lugol, these filiform, septate paraphyses, with intracellular pigment, some branched and that do not protrude above the level of the asci.
Again thank you very much for your help.
Kind regards.

Re : Claussenomyces?
Yes, this would fit Rodwayella. R.sessilis would be an option, but the group is difficult.

Re : Claussenomyces?
Thanks Zotto, it is best to leave it open like Rodwayella cf. sessilis or as Rodwayella sessilis sl.
It fits very well with the little information I have been able to find on Rodwayella sessilis.
Kind regards.

Thanks Zotto.
The information in your folder is very interesting, including a very detailed description of microscopy.
Kind regards.
