Polytrichum piliferum2 2024-03-25 SW Michigan USA To sexually reproduce, this moss utilizes the splash-cup mechanism to disperse the sperm it produces from its antheridia. The splash-cup mechanism occurs when raindrops splash onto the antheridia, collect sperm, and are hopefully splashed onto the female plant, where the sperm can swim to the archegonia.<br />
