Saccobolus - Asci
The youngest ascus is in the middle and the ascospores are colourless (hyaline). As they age, the ascospores become thick-walled and deep purple to protect them from solar irradiation. Note that the ascospores are in a tight arrangement inside the ascus. In this species the asci are shot of together in a clump. The extra weight of the 'missile' allows it to be discharged a greater distance possibly up to 60 cm. Since it is a coprophilous fungus this is a distince advantage in assisting the spores to hit plant food sources at some distance from the fecal droppings of the herbivore.
