White-nose syndrome
The white-nose syndrome is a fungal disease affecting bats, caused by the fungus Pseudogymnoascus destructans. This disease is named for the characteristic white fungal growth on the noses and wings of infected bats. It has led to significant declines in bat populations in North America.
It's a fungal infection but I don't know if the "white stuff" is the fungus itself or dead skin-cells.
A special I just watched on PBS says that it is not spread from bats to humans.
Scientists are studying, and trying to find ways to prevent or possibly cure WNS. In Boston, lab tests show that several drugs can fight the germ and that some antiseptics might help decontaminate areas where bats live.
No one knows. However, scientists are working hard trying to find it!
White Nose Syndrome in bats - a fungal infection. As well as being debilitating anyway I suspect it may be worse for the Horseshoe Bat on which the characteristic nose-leaf is a critical part of the animal's navigating and hunting echo-location.
Don't pick your nose.

A white tiger's nose is typically pink in color.
Cave-dwelling bats experiencing a disease outbreak with a high mortality rate could be suffering from White-nose Syndrome, a fungal infection that affects their skin during hibernation. This disease weakens the bats, leading to death from starvation, dehydration, or secondary infections, resulting in significant population declines within affected colonies.
