Ascomycete on bat poop in cave
Warre Van Caenegem, 24-06-2025 14:00
I'm currently in Croatia doing fieldwork that is not quite related to fungi. But in a small cave, I've found these tiny stalked cup fungi growing on individual bat poop droppings, probably from a Rhinolophus bat.
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.

Dear Warre,
I am writing you officially as an member of the State project that is currently concerned on a cave fungi. Together with my colleagues we are working on a group to which member you have came accross. If you collected anything, please send us your whole collection to legalise your activity and thus making you a collaborator of our project. ANY collecting of biological material in Croatian caves IS STRICTLY PROHIBITED.

ME and my colleagues would like to continue our further conversation through the e-mail. My official address is nmatocec@irb.hr. I will write you today to establish our further communication.

Best regards,

Dear Neven Matocec,

Thank you for your response. Awaiting your personal email communication, I would like to specify that I currently volunteer for Operation Wallacea, a UK-based conservation organization. Here, we are working together with BIOTA, a Croatian based conservation organization, in and around Krka National Park.

I would like to contribute to your project, and I will wait for any further instructions.

Best regards,
Warre

Re : Ascomycete on bat poop in cave
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.
