Common Crystalwort - Riccia sorocarpa


This is one of the commonest Riccia species and grows in irregular rosettes up to 2 cm diameter. The thallus branches may be over 2 mm wide, are broader than long, greyish-green above, becoming brownish when old, and have a very conspicuous, sharply V-shaped median groove. The thallus sides are almost vertical, and meet the top at an acute angle. Small, colourless ventral scales along the margin are visible with a hand lens. Capsules become visible in decaying, older parts of the thallus.

Identification difficulty
