Candelariella vitellina forme lignicole.
This morph usually is yellow-brown. It grows on humid wood, more or less degraded. Rather frequent and well-developed on wood ship wrecks in abers and rias of Brittany. May also be found, but less frequently, on wood structures near the seashore. N.B. On top of much dryer pirching birds wood poles a different form may be found: Candelariella coralliza forme lignicole. Usually more golden yellow.
