In the depths of the forests

Giant fungus weighing over 2kg discovered

Deep in Chinese forests, researchers found a mysterious fungus standing half a meter tall and weighing more than two kilograms, genetic tests revealed it belongs to an ancient lineage dating back 65 million years, formed shortly after the dinosaurs' extinction

In the depths of the forests of Yunnan Province in southwestern China, scientists have discovered an extraordinary organism that manages to surprise even veteran researchers: a giant whitish fungus whose body rises to a height of up to 50 centimeters and weighs 2.2 kilograms. But the impressive dimensions are only the beginning of the story.

The new fungus, which received the scientific name Dianjunus rex, or D-rex for short, was discovered during scientific surveys in the region's forests. It grows on tree roots and displays a large, upright structure unlike the fungi most of us know.

A research team from China, Thailand and Mexico collected samples from the fungus and conducted genetic and morphological tests. The results were particularly surprising: the fungus is not only a new species to science, but also represents a completely new genus and biological family, which received the name Dianjunaceae.

The fungus's exceptional size raises questions. Until now, the largest fruiting bodies documented in its group reached heights of only about 20 to 30 centimeters. The new fungus is significantly larger.

One hypothesis is that its enormous dimensions give it an advantage in dispersing spores by wind, above the dense vegetation on the forest floor. However, creating such a large body requires a significant energy investment, and it is still unclear how this exceptional trait evolved.

The study, published in the scientific journal Frontiers in Fungal Biology, highlights how much of the fungal world remains unknown to science. According to the researchers, the forests of East Asia may harbor many more species yet to be discovered.
