Caloplaca ceracea

Caloplaca ceracea, similar to Caloplaca crenularia which, incidentally was photographed on a wall close to St Brelade's Churchyard in Jersey, is characterised by some of the fruits becoming greenish when wet as can be seen in this photograph taken in the grounds of Elizabeth Castle in Jersey. It is usually on stone closish to the sea. Here, however, and most unusually it is on a piece of wood which was part of the base of a cannon. It is fairly frequent, but found fairly close to the sea. Occasionally, it can form a mosaic with Caloplaca crenularia, when the differences can be easily seen.
