Scientists discover 'D-rex', a giant fungus from Chinese forests whose unique lineage dates back 65 million years

Deep in the forests of Yunnan, China, scientists have discovered a "fungal giant" that challenges our understanding of how large fungi can become. The newly described species, Dianjunus rex, produces vertical fruiting bodies up to 50 cm (20 inches) high and weighing up to 2. 2 kg (4. 9 pounds)—the largest known within the phylum Ascomycota.
