Riccia cavernosa, also known as cavernous crystalwort,[1] is a species of liverwort which belongs to the family Ricciaceae.[2]
Description
R. cavernosa develops in rounded rosettes that can reach up to 3 cm in diameter, consisting of numerous lobes that are either oblong or rounded, with their widest part located above the midpoint. The lobes can measure up to 2.5 mm in width and feature a tip that is more or less truncate. Typically, the plants exhibit a yellow-green colour, lacking any reddish pigmentation, and they maintain a yellowish appearance even when dried. The upper surface displays a very short, subtle groove located solely at the tip, along with perforations that extend nearly to the tips of the branches.[3][4]
Discovery
At present, it is estimated that there are 250 species of Riccia, with 152 being widely recognized, while the rest are classified as either 'doubtful' or 'poorly known'.[5]
Riccia cavernosa was identified in New Zealand in February 2016, found at the edges of several artificial wetlands created to support the recovery of a threatened native wading bird (Himantopus novaezelandiae).[5][6] That same year, it was also found in Vermont, growing in the cracks of cement walkways in the city of Burlington.[7][8]
Habitat
R. cavernosa is generally found in moist, exposed environments with neutral to base-rich mud found near reservoirs, lakes, and ponds. It can also be found in damp depressions within agricultural fields, gravel pits, and sand dunes.[3][9]
Awards
In 2022, R. cavernosa was awarded the Latvian moss of the year.[10]
