I have a very simple microscope available, without a 100x lens and I cannot make measurements currently, and no literature.
I'm just very curious what these fungi are, so I hope that the data I can provide might help to get to a genus or species.
Asci 8-spored, with simple septa (no clamp at base). Excipulum with round cells, some of these cells have brown content. Paraphyses are not very obvious, but there are several long, thicker-walled strands in here, which are multiseptated and seem to be filled with greenish/brown content (it kind of looks like a filamentous algae).
I tried to search for Literature and observations of ascomycetes on bat droppings, but I could not find something that looks like this.

Difficult to tell without measurements, iodine reaction, and living features. The paraphyses surely contained VBs which now in dead state appear distorted.
The absence of croziers I would doubt a bit, it is not evident on your photos.
The excipulum could point to a Sclerotiniaceae (?), which depends on the type of amyloid apical ring of the asci.
