Hi
At the time of finding, there was only one immature apothecia. The rest of apothecia has grown at my home in about two weeks. Part of Apothecia grew directly on the cone, other apothecia from the remains of plants adjacent to cones.
Spores ornamentation directs me towards A. michaudii but both the substrate and the size of the spores do not match this species.
Do you have any other ideas ???
Below I present spores from two ascomata although I studied more.

Re : Ascobolus from spruce cones.
Hello Chris
I did not answer for a long time but that's because I was intensively searching my name for my collection. Unfortunately, I could not find answers to the most interesting topic. I am wondering the diverse ornamentation of spores and especially the occurrence of ornamentation in the form of transverse lines. In principle, all qualities fit A. lignatilis.
I place a few additional photographs.
Thank Chris for your help!
Other comments are welcome, the more so that this species is completely unknown to me.
Can I call him A.lignatilis ??? ... What is your opinion?

Re : Ascobolus from spruce cones.
Hello Myrek.
Are you sure it is the same mushroom on your two messages? The size of the spores and their ornamentation appear to be different. For your first message, it could indeed be lignatilis, even if this ornamentation is quite surprising, although it is quite variable for this species.
Michel.

Re : Ascobolus from spruce cones.
Hi Michel.
I suspect that the second Ascomata was not mature and therefore the spores had smaller dimensions.
I studied a few apothecia and their construction was the same so I suspect that this is the same species. Spores with transverse ornamentation occurred in all examined Apothecia only in other proportions. The more mature apothecia, the more spores with irregular ornamentation.
As I mentioned before, apothecia was grown in artificial terms. I suspect that in such a situation, features may differ slightly from cultured under natural conditions.
Below I place one more photos of spores from the second Apothecia. You can also see spores with irregular ornamentation but already in a smaller amount.
Thank you for dividing yourself with insights and comments.

Re : Ascobolus from spruce cones.
A few more photos of the first apothecia. The density of ornamentation on the spores seems to be very similar. What do you think?

Re : Ascobolus from spruce cones.
Your photos show the variability of this species. Maybe you could keep it in a herbarium if you have enough apothecia to be able to compare and thus verify during a next harvest that it is indeed lignatilis.

Re : Ascobolus from spruce cones.
Thank you for all your comments. I hope that I will find this genre again and then I will be able to compare the features. On this substrate Ascomata no longer grow, but I gathered a few pieces so I will have material to compare.
The variability of spores ornamentation is actually quite large which surprised me completely.
With your help, I have the conviction that the species determination is correct.
Thank you again and greet.
