(CNN)-- In the depths of humid forests, specifically among dead tree trunks and fallen branches on the ground, hides the "bleeding fungus", one of the strangest types of decomposing fungi in the world.

What is its secret?

When this small fungus, known as "Mycena haematopus", is scratched, it secretes a red liquid that closely resembles blood, but it is actually the result of natural chemical reactions.

Some scientists suggest it forms a defensive mechanism against insects, bacteria, and other fungi, while others believe it may help protect the fungus's tissues from damage.

The "bleeding fungus" is found in various regions around the world such as America, France, and Asia. Although it is not poisonous, it does not have any nutritional value that makes it suitable for consumption.

Lebanese mycologist researcher Sandra Sleiman was among the lucky people to document it with her camera lens. (Watch the video above)

She said in an interview with CNN Arabic: "I was walking in the embrace of Lebanese nature when I stopped my friends and told them we had found a rare and strange type.. It was an exceptional and very spontaneous moment."
