A beautiful piece of art by Podospora setosa species

Found on rabbit pallets.I have never seen this phenomenon during my research, the resease of asci from P. setosa.
In a field of P. setosa of over 50 species the process of asci release was in full swing.
At first a sticky bubble is released out of the ostiole channel and after that one by one the asci are creating these small pieces of art.
Photos 1 & 2 are showing the ongoing process fisrts one is coming out and 5 seconds later the second one joins.
The other photos are final crations.

Re : A beautiful piece of art by Podospora setosa species
Hello Joop..
Great photos! It is unusual to see so many asci crowded at the top of a perithecium like that. Usually you would expect them to migrate up to the ostiole and then discharge their ascospores. I wonder if conditions were too dry to allow the spores to be discharged. Maybe those are just the masses of ascospores held together by the gelatinous appendages. Did you make a mount of the asci to see if the walls were still intact?
