The single local species of Straminergon (previously placed in Calliergon) is a plant usually associated with Sphagnum in boggy sites. It is the only local plant with the combination of a costa extending above mid-leaf, a broadly rounded leaf apex, and a large alar group of inflated and thin-walled cells. The closely inserted, strongly overlapping distal leaves of the stems and branches form a bluntly acicular apex of each axis.
