A - Laurencia sensu lato (check the key of Canary Islands)
B - Callophyllis sp. (check the key of the british isles)
C - I would say Gigartina pistillata (Check the transversal section and the key of Galicia)
D - Check Taonia (in the tips if it is grotwing by one lenticular cell -Dictyota-, a line of cells -Taonia- or by filaments -Cutleria-, you can check the key of the Canary islands)
E - It is a picture and seem to be Palmaria but check also Stenogramme interrupta.
