Asco opening with a longitudinal slit on Juniperus
Per Vetlesen, 27-03-2017 10:55
Hi,
I have found this asco two times on bark of Juniperus communis in Stange, Norway. The first time I found it on bark of a dead tree and the second time on bark of an old living tree.
Asci (142.1) 142.5 - 175.6 (188.8) × (23.3) 24.3 - 27.2 (33.4) µm; Q = (5.2) 5.6 - 6.9 (7.2) ; N = 10; Me = 166.6 × 26.2 µm ; Qe = 6.4
Ascospores, mostly 1-septate, some are 3-septate, (45.8) 48 - 57.4 (58.1) × (10.3) 10.7 - 12.6 (14) µm; Q = (3.8) 4.2 - 5 (5.6) ; N = 27; Me = 53.8 × 11.5 µm ; Qe = 4.7
I hope characters shows on the pic, if not please tell me and I will check it again.
Best wishes

It looks like a bitunicate asus to me, judging by the constrictions at the ascus apex. Nice photos of asci and ascospores!

Re : Asco opening with a longitudinal slit on Juniperus
Thank you for comments. Yes, it is has bitunicate ascus, I think it is a Dothideomycetes, but I have no idea of family or genera.

Re : Asco opening with a longitudinal slit on Juniperus

Hi Per,


How is the ascomata ? Is it perithecial ? and what about the hamathecium ? Could it be interesting to compare to genus like Ostreichnion ? I think that is not very possible. But it's only an idea.

Hi Aain,
I'm novice when it comes to scientific terms (but hope I'm learning) and I hope these pic give answer to your questions.
To me it looks like it is perithecial and opens with small split. I have tried to make better picture of it. When I come to hamathecium I understand that it is the tissue between the asci?
The spores do not have a gelatinous sheet.
I have looked at Ostreichnion at http://www.eboehm.com/, but can't find any that fits.

Yes, I agree, it was just an idea. I had other (not good) ideas, like Xenolophium, but not the solution.


It is a beautiful fungus.


Alain

Hi,
Thank you very much for trying to help.
I too have thought about Xenolophium.
Yes, it is a nice fungus and the spores are very characteristic.

Re : Asco opening with a longitudinal slit on Juniperus
Is the material air-dried? If so, and if you have material to spare, I may try to get it into culture and sequence it from that. Then we may have a good shot at a good sequence and can see if it blasts to anything, as well as to see if it forms an anamorph in culture. That is if spores will germinate and grow.
Your fungus reminds me of something that I saw in literature in passing while trying to figure out another of these intactable brown-spored, single-septate, bitunicates. I can only get so far as "Dothideomycetes, Pleosporales, sp."! I will try to retrace my steps and see if I can't find what I saw in the literature.

Hi Jason,
That's great! The material is air dried, but I will try to find some more before sending it to you.
