Dothideomycetes
Per Vetlesen, 17-11-2016 22:12
I have collected it on inner bark of dead Betula pendula and Sorbus aucuparia in Stange; Norway.
Spores of the one collected on Betula: (20.4) 21.6 - 24.2 (26.3) × (9.1) 9.2 - 10.5 (10.9) µm; Q = (2.1) 2.14 - 2.5 (2.8) ; N = 26; Me = 22.9 × 9.8 µm ; Qe = 2.3
Spores of the one collected on Sorbus: (18) 19.7 - 23.3 × (8.8) 9.1 - 9.6 (9.7) µm; Q = (1.9) 2.1 - 2.4 (2.5) ; N = 7; Me = 20.9 × 9.3 µm ; Qe = 2.2
I have no idea, so any help is welcome!
Greetings Per

Re : Dothideomycetes
Apiorhynchostoma curreyi?

Re : Dothideomycetes

No, Apiorhynchostoma doesn't fit.


I have already found this fungus on Betula and Sorbus, but it's yet unnamed.


Sorry,


Alain

Re : Dothideomycetes
Pavol, thank you for suggestion.

Alain, that's very interesting. I have been in contact with Geir Mathiassen, he has also found this fungus in Finnmark, Norway. He found it on Betula pubescens and Alnus incana and suggested that it might be an undescribed species in a publication 2012 page 12 and 30 with a pic of the spores fig 78:
http://www.artsdatabanken.no/File/1049/Mathiassen%20G.%20og%20Granmo%20A.%202012%20Sluttrapport%20for%20Artsprosjektet.%20Sekksporesopper%20i%20Finnmark%202010%E2%80%932011.%20Troms%C3%B8%20Museum,%20Universitetsmuseet%202012,%20ADB%2056-09,%20Prosjekt%2070184216
Where did you find it?

Re : Dothideomycetes

Yes, same fungus apparently.


A very very interesting paper for who likes pyrenomycetes.


2 remarks about Hysteriaceae :


Gloniopsis praelonga shown  is not different from Hysterobrevium smilacis, now named H. curvatum.


and also : H. acuminatum= H. angustatum.


 


Incredible land they have in Finmark !


Thank you,


Alain

Re : Dothideomycetes
Yes, it is an interesting paper.
Thank you for the remarks on Hysteriaceae. I am doing survey on Fungi in Rotlia Naturreservat, that is where I found the fungus we have discussed here. I also found Hysterobrevium smilacis/ curvatum/ praelonga there and have made some notes about the names and synonymity. In the report I am going to write about Ascmycetes in Rotlia Naturreservat the unnamed Dothideomycetes will be shortly mentioned and that you apparently have found the same fungus. I guess you found it in France?

Thanks
Per

Re : Dothideomycetes
Why not sequence it and describe it as a new species in Fungal Planet?  Lots of Hysteriales sequences to compare it to.

Re : Dothideomycetes
Hi Andy, that's a good suggestion. But my material consists of just the fruit bodies on the pic and I do not have the facilities and knowledge to make a culture of it, or how to handle DNA sequences. If I find more material I'll try to get somebody to help me.

Re : Dothideomycetes
Dear Per,

   If your material consists of 15-20 fruiting bodies, send it to me and my technician can sequence it for you.  We only need 5-10 fruiting bodies to extract DNA.

Best,
Andy
Per Vetlesen, 22-11-2016 22:51
Re : Dothideomycetes
Hi Andy,
thank you very much for your generous offer! Unfortunately the material consists of only the 3 fruit bodies, you can see on the first photo, and it looks like the small one is empty. But I'll go and try to find more next week.
Thank you,
Per

Re : Dothideomycetes

Hi Andy,


Happy to read you.


My record was from France. I had got many ascomata, but it was collected in 2013.


It's located in mountains (alt. 1300 m, probably covered by snow now). Next year I will be able to collect it.


Best wishes,


Alain

Re : Dothideomycetes
Dear Per and Alain,

   It would be best to send me material from both localities so we can compare their ITS sequences and better understand mycogeography.  Next month or next year is fine.  This would be an interesting new find!

Best,
Andy

Re : Dothideomycetes
Andy has sequenced this "fugus" and writes:
"I finally sequenced your PV-R351 collection and the results are odd. The ITS-LSU region BLASTs to Umbilicaria in GenBank, but there is a Gloniopsis at the bottom of the list with about the same query coverage and similarity as Umbilicaria. I tried BLASTing the ITS and LSU separately and I get similar results - either an Umbilicaria or a Hysteriales. The sequences were good although the material was not in great condition. Is it possible that this is a lichen?"
Thank you very much, Andy!
All the best
Per
