A typical Perigordin habitat for this small fern. The Common maidenhair Spleenwort (Asplenium trichomanes subsp. quadrivalens) has chosen as a place to live the ruins of a stone wall of an ancient farmhous, abandoned during rural depopulation in the former century.
It covers part of the wall with its drooping fronds.
Here it grows on an old treetrunk covered in mosses and ivy. The little fronds are glistening from rain.
