It has been suggested that the Permian–Triassic boundary is associated with a sharp increase in the abundance of marine and terrestrial fungi, caused by the sharp increase in the amount of dead plants and animals fed upon by the fungi.
Suxeriuse que o límite Permiano-Triásico está asociado cun súbito incremento na abundancia de fungos terrestres e mariños, causado polo brusco incremento na cantidade de plantas mortas e animais que se alimentaban de fungos.
