Dichelyma uncinatum

Dichelyma uncinatum is an aquatic or semi-aquatic moss in the family Fontinalaceae, typically found anchored to submerged rocks or wood in cool, clean streams and wetlands. It requires constantly wet to submerged conditions and cool, well-oxygenated water, making it suitable only for naturalistic bog gardens, cold-water aquaria, or stream restoration projects. This is a highly specialist species rarely found in cultivation and not appropriate as a standard houseplant.
