Black Orbilia? (Patinella hyalophaea)
Nihad Omerovic, 11-07-2015 17:25

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.

Hi Nihad
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?

Re : Black Orbilia?

Thank you very much, Zotto, great!


I cut out a chip of wood with a few fruitbodies; I wouldn't say it's abundant (more stayed at the location), but I'll keep it.


I think I had the same species last year at different location (close to me)  (picture)


 


Thanks again

Re : Black Orbilia?
Yes, it is the same species. Did you preserve this sample? What could be the substrate in both? Coniferous or deciduous?

I apologize, I erroneously wrote abietina but I meant Patnella hyalophaea.

Re : Black Orbilia?
Hi Nihad,


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:

Guy Marson,
45B, rue de Bettembourg
Pack-up #63686405

Thanks a lot!

Best regards,  

Guy

Re : Black Orbilia?

@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?

Re : Black Orbilia?
Interesting when the substrate may change that way! I assume you can separate conifers from viewing on a crossbreak of the wood?
Nihad Omerovic, 13-07-2015 20:40
Re : Black Orbilia?

Hi, Zotto


I think I can recognize conifers quite well, but I may be wrong; that's what I recorded and here is another picture from last year where you can see the crossbreak and light colored wood (separated ring). What do you think?

Re : Black Orbilia?
Could be coniferous, but to be sure you need to look on the pores, not on the fibrous face. Look from the left on the break and with higher resolution, then you see if there are only minute pores or also larger ones. It is not completely easy because conifers may have resinous canals that resemble the pores of angiosperm wood.
Nihad Omerovic, 13-07-2015 23:35
Re : Black Orbilia?

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...

Re : Black Orbilia?
Hi Zotto and Nihad,

"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

Re : Black Orbilia?

Hi,


 


 I've sent the sample.
