A quick visit to St Mary's Church Hayling Island

 St. Mary's Church is one of a few known locations for Rocella phycopsis in our area, it is more than 20 years since it was last recorded so I popped by to check up on it. Restricted to the north east corner of the church building the colony seems in robust good health, older clumps producing plenty of soredia and some younger individuals coming on.

There was an odd looking mosaic on a dark block of 'ironstone' incorporated into the wall

some internet research found a very similar mosaic recorded from stained glass in Brittany

so it looks as if this is Llimonea sorediata although the authors are not quite sure if it isn't Dirina massiliensis.........

There was some Dirina massiliensis on the church, here it is muscling in on a very areolate Arthonia (Opegrapha) calcarea and Caloplaca dalmatica
