A WOMAN was left terrified after ripping up her floorboards and making a gruesome discovery.
The Australian quickly turned to Facebook to find out why her floors were covered in a giant web-like growth.
After the disturbing images were posted on Facebook, even experts were baffled as to what had caused the growth that looked like something straight out of Stranger Things or The Last of Us.
She told Yahoothat she had shared the pictures of the growth under her floorboards on behalf of her friend.
The images show the floors of her home covered in a strange dark pattern that stretches across the floor.
The woman shared it in a local group on the social media app to see if anyone else had an idea what it was.
However, it is not surprising that many did not know what the cause could be and that the images terrified them.
“I’m really terrified,” one wrote.
Some users in the group suggested it could be “mycelium,” “slime mold,” or some type of tree roots, but the community couldn’t agree.
Even experts are puzzled after being shown the pictures.
An expert at the State Herbarium in Brisbane told Yahoo: “It’s something new for me too. It definitely doesn’t look like traditional mold.”
The expert added: “The only thing I know that looks close to this is the rhizomorphs of Armillaria (honey fungi), but that doesn’t make much sense.”
According to Britannica, a rhizomorph is a “thread- or cord-like structure in fungi” that consists of “parallel hyphae, branching tubular filaments that form the body of a typical mushroom.”
Elizabeth Aitken, professor of plant pathology at the University of Queensland, also agreed that it “looks like the rhizomorphs of a wood rot fungus”.
She explained: “Whether it’s dry rot fungus or something else, they would have to take samples or ask a wood specialist.”
Dr. Heike Neumeister-Kemp, senior mycologist at Mycolab’s managing director, added: “This is definitely a fungal mycelium, most likely derived from a basidiomycete.”
Apparently this type of mushroom is “actually harmless” and forms a fruiting body (poisonous mushroom or fungus).
