Gibellula pulchra is a species of parasitic fungus found on arachnids.

The species Gibellula pulchra is commonly found around the world.

[2] Like other ascomycetes, Gibellula pulchra can be found under stones, bark, leaves, on decaying logs, or in hidden burrows of plant matter on the forest floor.

[5] Often Gibellula pulchra is more clearly identified after entering an arachnid, enveloping their host, and growing on their cadavers.

In order to attach to a host, Gibellula pulchra sends out spores.
