Distinguishing Features

An uncommon to rare species, R. trichocarpa forms small rosettes (~1cm wide) on thin soils with open exposure. These rosettes are distinguished by an abundance of hairs present all around the margins and underside of the plant.

Similar species

Riccia beyrichiana also has marginal outgrowths, but they are much shorter, much wider and much less numerous than those of R. trichocarpa. No other Riccia species has the abundant fine hairs of R. trichocarpa.

Habitat

Seasonally moist fine mineral soil, especially around steeper and rockier seepage sites and ephemeral pools. Uncommon to Rare, SW & SC BC.

Associated species

Gemmabryum barnesii, Pottia truncata, Riccia sorocarpa, Riccia beyrichiana, Riccia nigrella, Riccia cavernosa, Pleuridium acuminatum, Philonotis capillaris
