Here is something that is common yet many have never seen, Sphagnum sporophytes.
I originally imported this species live from New Zealand many moons ago. This culture is a descendant of the original cultures that were featured in my "Growing Sphagnum Moss" web page.
Sorry for the crappy pics but the humidity levels above the sphagnum was so intense the lens would fog up almost immediately, I had to move fast and hope for the best.
"...The sporophyte of Sphagnum consists of a nearly globose capsule and a foot; a seta is absent. At maturity, the sporophyte is elevated into the air by a stalk of gametophytic origin termed the pseudopodium. The capsule, like that of other mosses, is provided with an operculum, but a peristome is lacking and spore discharge, rather than being gradual, is explosive. Upon germination, each spore gives rise to a unistratose sheet of cells that forms multicellular masses (buds) from which the leafy gametophytes arise. "
