Identification notes
If you’re in soft limestone or chalk country keep an eye out for this very small, bright green species. When you come across a patch growing on a limestone rock in woodland or an arable field, your first impression is likely to be of a non-fruiting Weissia, for its leaves are long and narrow with incurved margins and end in a hooded or boat-shaped tip. But Weissia species don’t grow on rock. Look for it in dry but sheltered places.
