Small asco on the edge of the bonfire?
Mirek Gryc, 18-05-2022 09:10
Hello everyone
A few days ago I found a small ascoma on the edge of the fire (max. 4 mm in diameter). I am not sure if they are mature so I still grow them. I will try to get free spores and complete the documentation, meanwhile I post a few photos with the hope that someone will recognize this species. I apologize for the poor quality of the photos but I tried not to damage the ascomat, the more that the species is completely unknown to me.
multiguttulate ascospores:
(11.1) 11.3 - 12.4 (12.9) × (6.3) 6.4 - 7.2 (7.5) µm
Q = (1.6) 1.7 - 1.88 (1.9); N = 12
Me = 12 × 6.7 µm; QE = 1.8
I have the impression that they are surrounded by a jelly cover? For now, I can't clearly determine the character of ascospores, maybe I will be able to do it after obtaining free spores?
I did not observe any reaction to iodine.
All suggestions are welcome.
Regards
Mirek

Hi Mirek,

I would consider an immature Ascobolus carbonarius. Let's see how the spores mature.

Re : Small asco on the edge of the bonfire?
Hi Viktorie
I took him into consideration but too many features do not match him. I studied this species several times and seems different to me?
However, I do not rule out anything. I have a very unfavorable podoga. At night, even today, the temperature dropped below zero. Besides, rain is missing!
Thank you for the hint. I will try to show the features of how ascomata will mature.
Regards
Mirek

Re : Small asco on the edge of the bonfire?
Could this be a species of Anthracobia, something like A. subatra?
Mirek Gryc, 18-05-2022 18:38
Re : Small asco on the edge of the bonfire?
Hi David
I don't think it was an Antrocobia species.
The most interesting thing is that I can't adjust my collection to any kind. I no longer take into account the negative reaction to iodine which can sometimes be quite capricious. I had several Peziza collections that did not react to iodine at all, so there may be a similar situation here.
My ascomat has no hair. What can be seen in the pictures is more like rhizomorph and occurs at the bottom of ascomata.
Regards
Mirek

Re : Small asco on the edge of the bonfire?
I have an idea although the substrate contradicts it!
I see a lot of common features from Pseudombrophila porcina.
What do you think about it?
Mirek Gryc, 18-05-2022 21:27
Re : Small asco on the edge of the bonfire?
I reviewed one more sample under a microscope.
P. disciformis will probably be a better proposition :)

Re : Small asco on the edge of the bonfire?
I agree with you Mirek, Pseudombrophila disciformis seems to be the correct determination.
On the 16th photo, we can see the polar warts and some fine ridges on the surface. Yhe hyphoid hairs on the external surface are also a typical characters of Pseudombrophila spp.
Brummelen (1995) indicated the paraphyses to be swollen, but this is not really evident on your pics.
Very interesting collection of this very rare species!
Mirek Gryc, 20-05-2022 09:16
Re : Small asco on the edge of the bonfire?
Hi Nicolas
Watching the last sample, I noticed a delicate ornamentation in the form of an irregular mesh on spores.
Yes, you are right, the paraphyses peaks do not completely match. I haven't observed so far that they were thicker?
Also, the spores from the last sample is too small in relation to what Brummelen gives.
I did not download a few younger ascomat in the hope that maybe they would grow. However, I doubt that this happens, it is very dry :(
The one I downloaded I still hold alive, I have to see as mature as possible.
I think the sequences of this species have not yet been made? If you were interested in you, I will gladly send some of the collection. It is not much, but for research it should be enough.
It would also be nice to see spores under an electron microscope, unfortunately I do not have such a possibility.
In fact, this is a rare species so it would be good to use it as much as possible.
Regards
Mirek

Yes, it would useful to sequence this collection.
You can send to me a part of it.
