The root system in the cortex of the host stem has a few branches and highly simplified stele of original triarch vascular bundles. The haustrium root system, which is from the root system in the cortex of a host stem enters the vascular tissues as finger-like body from the vascular rays and then to become hyphae-like body among the vascular cells.
