Louis DENYBonjour forumSur tronc décortiqué de feuillu x,
Greetings to ascofrance community
I am an amateur from Bosnia and Herzegovina interested in ascomycetes. Although a member of this forum for several years now, this is my first post.
Here is the question
Found this fungus recently (end of June) on a riverbank, 730 m altitude, on a piece of wet deciduous wood.
Apothecia small, under 0,5 mm; spore size Me = 4.5 x 2.7 µm ; Qe = 1.7;
asci 48 x 5,7 µm, IKI negative.
Can anybody help to identify it?
Thank you.

welcome to the forum!
This is a great collection: Patinella abietina (sorry, I meant hyalophaea). It is known to me only from the type collection from Italy and from a recent sample from Canada (see paper attached).
I gave the Canada sample for sequencing but it appears that it did not work. So, please keep your sample in the dry state to permit such analysis. is it abundant enough?

I apologize, I erroneously wrote abietina but I meant Patnella hyalophaea.
Zotto
Could you please send a little part of this very interesting species to me? With 3-4 apothecia, I could try to make a culture on CMA and with the remaining I could try to get a sequence. My address is:

Thanks a lot!
Best regards,

@Zotto
Aha, OK, I've just realised they are not synonims and wanted to ask...
I checked the last year exicata - it's either missplaced or not saved (I have other samples from that day...)
Anyway, the last year's collection was in August, 950 m, on coniferous wood (picture); this year's - deciduous.
@Guy Marson
Yes, of course. Zotto?


Thank you, Zotto. Last year I was sure, but now I don't remember, only what I wrote down. Don't have a more detailed photo of the substrate. I'll visit the place soon, so who knows...
Regards
"I gave the Canada sample for sequencing but it appears that it did not work. So, please keep your sample in the dry state to permit such analysis."
The sample you sent me some months ago (if you mean that one?) gave a sequence. I will send the sequence to your new email address. Nevertheless it would be good to sequence the new collection from Bosnia Herzegovina..
Best regards,
Guy
Hi,
I've sent the sample.
Best regards
