Hello, everybody!This one was collected in 2008 year on bark of Acer tataricum. Actually, I don't have credible ideas, what this can be:(
Dimensions:
Apothecia: up to 0,5 mm in diam, 0,4*0,8 mm.
Sporesize: 15,3-17,8* 5,3-6,3 um, mature become 1-septate
Asci: 90-100*10-12 um
Apical pore blued in IKI
Pleace, help!
Thank you,
Irina

Re:Odontotrema or something strange?
Here you should show us the IKI-stained apical ring in big resolution. Presently I have no idea.
Also a median section through the apothecia showing the excipular cells (perhaps in KOH) would be helpful.

Re:Odontotrema or something strange?
Dear Martin, Is unitunicate or bitunicate? Macromorphology and characters for me resembles to Rhytidysteron, but its a Patellariaceae. You could see the paper: Murillo, C. et al. 2009. Molecular data indicate that Rhytidhysteron rufulum (ascomycetes, Patellariales) in Costa Rica consists of four distinct lineages corroborated by morphological and chemical characters. Mycological Research 113: 405-416. Rhizodiscina lignyota has brown and inequilateral spores, and the base of asci are narrow and long. I hope you find it helpfull. Best wishes Luis.

Re:Odontotrema or something strange?
Hi Luis,
I don't have seen Rhytidisteron and Odontotrema either. I am looking forward to some new micros of Irina for further discussion. Rhizodicina was just a spontaneous guess...

Dear Zotto and Martin,
Thank you for your ideas.
I'll post photos of median section through the apothecia and apical pore as soon as I can.

Re:Odontotrema or something strange?
Bonjour à tous,
For Luis ; now the genus Rhytidhysteron is now in Hysteriaceae (See Boehm and al. in a recent SIM). Itsn't one of them here.
I don't think it could be Rhizodiscina too, as Luis. Here we need a median vertical section, as Zotto said, and perhaps more precisions about ascospores.

Re:Odontotrema or something strange?
Here is some more ascospores (septate and non-septate) and stained apical pore.
Actually, staining was rather weak.
Unfortunately I have no possibility to make photos with better resolution:(
Placed in KOH 3 %, ascocarps began to extract bright cherry-colored pigment!
I'll tried to make a section, but it was all dark because of this pigment.

Re:Odontotrema or something strange?
Did you see the red pigment extruding into the medium? My idea is a Dermea (which shows such a strong iononmidotic reaction in KOH), but on Acer I do not know if this is possible.

My ideas turned around Dermea, or other Dermataceae, too. But without concrete idea.

Re:Odontotrema or something strange?
Dear Zotto, Alain, Martin,
Yes, I saw bright red pigment.
Maybe, collector made a mistake concerning substrate...
Is anyone interested in this specimen (from Ukraine, Kharkiv district)?
I can send doubles to everyone who will have time to take a look on them.

Yes, this is a good idea! I know this species only from Groves 1938. I do not know whether it has a conspicuous pycnidial anamorph.

Re:Odontotrema or something strange?
I have some samples of this species from Ukraine (both anamorph and teleomorph).
Some of them were tested by Dr. Popov from Russia.
If you interested, I can send you duplicates for your collection.

Re:Odontotrema or something strange?
Hi Alex
This would be surely great to have a look at them. But even more happy I would be if you have macro- and microillustrations of that species. Do you?
