Scientists have recently discovered what could be the largest and oldest living organism on Earth, a giant fungus that is an interwoven filigree of mushrooms and rootlike tentacles spawned by a single fertilized spore some 10,000 years ago and extending for more than 30 acres in the soil of a Michigan forest.
原句是说科学家最近发现了一个东西, 是世界上最大,最古老的活体器官, a giant fungus...是个同位语吧? that 引导定语从句修饰 fungus, 定语从句就说这个东西由2部分构成mushrooms and rootlike tentacles, 接着就是用spawned…and extending…的平行结构作后置定语修饰rootlike tentacles
