The fungus grows parasitically on the mycelium of wood-rotting corticioid fungi in the genus "Peniophora". The fertilised carpogonium develops growing parasitically attached to the female plant. These are myco-heterotrophs and feed parasitically off of one or more of the local mycelia. Some species are known to exist parasitically within termite nests. It mostly grows in tropical rainforests and lives parasitically on fungus to survive. A barnacle, "Megatrema anglicum", is often found living parasitically inside "Leptopsammia pruvoti". The fungus grows parasitically on a large number of broadleaf trees. Its life cycle involves a stage where it lives parasitically inside a fish. There are about 18 species, which live parasitically in the leaves of deciduous trees. It can be parasitically infected by "Avetianella batocerae". The entire Torah would have been parasitically borrowed from ancient Oriental sources.
