Note Usually, the most available parasite is the dodder. It 

 is common in swales from July until autumn, winding its coral- 

 yellow stims about herbs and soft-growing hushes. It is a degraded 

 member of the morning-glory family. It produces true flowers and 

 seeds. These seeds germinate the following spring. The Blender 

 young vine grows from the ground for a time, but if it fails to find a 

 host, it perishes. 



Tin- cultivated mushroom, a saprophytic plant.
