Re : Fungi on straw
Hello, William, this should be Orbicula parietina.
Sincerely, Norbert

Re : Orbicula parietina on straw
Thank you very much Norbert!
I did some follow-up research and it fits the description of Orbicula parietina very well.
I think the peridium is two-layered, see pictures of exoperidium and endoperidium. The hyphal hairs seem to be constricted to the peridial base. Together with the spore size (8,9-10,3 x 9,3-10,9 µm) this should exclude Lasiobolidium orbiculoides.
Do you still agree with Orbicula parietina? A confirmation would be nice. :)

Re : Orbicula parietina on straw
With uniseriate asci and this spore size it's clearly Orbicula parietina, William.
