    $\begingroup$ Welcome to Biology.SE! Please edit your post to include the size of these structures, where they were located in the cave (e.g. on the walls near the entrance), and why you concluded they were fungi. ——— If possible clear, closeup photos of the structures from multiple angles would also be helpful. Thanks! 😊 $\endgroup$

I think these are parasitized insects.

Fungi of various types can infect insects. The end stage produces these fruiting bodies. Here is an example I found on the excellent site WhatsThatBug.

moth with fungi

Here is another example.

moth with fungus


The second site notes

Entomopathogenic fungus (Clavicipitaceae sp.) killed a troglophile moth, Veins cave (Grotta delle Vene), Italy

I would guess something similar for what you found.

I must say your images are incredible. The long fungal tendrils on the second image are the most amazing example of this I have ever seen.
