Ballistics of spore and sporangium discharge in four coprophilous fungi based upon high speed video analyses and different models for the effects of viscous drag on particle flight.

*Maximum range measurements by authors with exception of P. klenii data published by Buller [19].**Pressure estimates (for measured range of launch speeds) were obtained by calculating the force needed to cause the observed projectile accelerations via Newton's second law and the area over which that force was applied.
