he he- not admini today but adgreaty
Very good- it is the young developmental stage of Orobanche crenata. The blackish ball is the tiny seed, staying in the soil up to 10 years and waiting for a root of Faba Bean (Vicia faba). Then it germinates (the tiny small fibre, which get the contact to the host), and at the contact area with the host root, the fibre swells to a haustorium, penetrating the host tissue to get all its nutrition. Here are 2 additional pictures, the first one is the stage before the pic of the quiz, the second one is the stage afterwards. From this pretty big subterranean balls the flowering stems will develop, and the bean will be dead soon!
Btw: this happens in all species of Orobanche.
