Distinguishing Features
A rare species thus far known only from sloping and seasonally saturated fine sediments over rock, R. lamellosa appears as small (~5mm) thalli with a smooth upper surface, v-shaped tips on a whitish-green plant. Close inspection reveals a series of thin pale flaps ("lamellae") that fringe the edges of the plant.
Similar species
No other species of Riccia has the overlapping scales of pale tissue along the margin, making this plant unmistakeable compared to others in the genus.
