Note the dark, bristle-like appendages growing over the sexual stages (gametangia) of the fungus. Some claim that the appendages are there for protection of the richly protoplasmic sex cells (progametangia and gametangia). Others claim that the spiky bristles help in dispersing the sexual spore (zygospore) that is the result of the fusion of the gametangia. What do you think and why? The swollen cell that produces them and also the gametangia is called a suspensor and the appendages are therefore called 'suspensor appendages'. In this strain the appendages only arise from one suspensor.
