 Dictyopteris membranacea with sea lettuce

Observation - Dictyopteris membranacea with sea lettuce - UK and Ireland. Description: I am sure about the sea lettuce (Ulva lactuca) but not absolutely sure about the Dictyopteris membranacea. It looks more purple than the green/brown colour it is described to be in a Guide to Seashores and shallow seas (Philip's: Andrew Campbell)
