Kindbergia

This is the tiny sporophyte of Kindbergia oregana, a very common Pacific Northwest moss which grows in lush carpets over the ground, rocks, and maples on Keats Island. The outer row of teeth in the sporangium are hygroscopic - they move in response to humidity. When the air is dry and perfect for spore dispersal, the teeth flick outwards, throwing spores into the wind.
