Cyathus Helenae - Spore Dispersal

Spore Dispersal

When a drop of falling water hits the interior of the cup with the appropriate angle and velocity, the peridioles are ejected into the air by the force of the drop. The force of ejection tears open the purse, and results in the expansion of the funicular cord, formerly coiled under pressure in the lower part of the purse. The peridioles, followed by the highly adhesive funicular cord and basal hapteron, may hit a nearby plant stem or stick. The hapteron sticks to it, and the funicular cord wraps around the stem or stick powered by the force of the still-moving peridiole. After drying out, the peridiole remains attached to the vegetation, where it may be eaten by a grazing herbivorous animal, and later deposited in that animal's dung to continue the life cycle.

... Both asexual and sexual spores or sporangiospores are often actively dispersed by forcible ejection from their reproductive structures ... This ejection ensures exit of the spores from the reproductive structures as well as traveling through the air over long distances ... Specialized mechanical and physiological mechanisms, as well as spore surface structures (such as hydrophobins), enable efficient spore ejection ...
Cyathus - Spore Dispersal
... Like other bird's nest fungi in the Nidulariaceae, species of Cyathus have their spores dispersed when water falls into the fruit body ... "splash cup", where it may break and spread the spores within, or be eaten and dispersed by animals after passing through the digestive tract ... This method of spore dispersal in the Nidulariaceae was tested experimentally by George Willard Martin in 1924, and later elaborated by Arthur Henry Reginald Buller, who used Cyathus striatus as the model species ...
