Description

Covering the small shores of the creek that runs through Ravenna Park, this prehistoric-looking species is prone to swampy, moist conditions and prefers a wet habitat. They grow in dense clusters of green, jointed, hallow stalks and having both a sporing stage and a fruiting stage. During the sporing stage they are topped with a small spore cone which is the fruiting body.

They are still very small, and are almost all less than 8-10 inches, I wonder how much taller they will grow!
