Specimens were found with Cladophora sp. and Enteromorpha sp. on the tide line of pontoons at Newlyn Marina, Newlyn, Cornwall. 29.05.16 and 31.05.16.

Unverified identification made using a microscope and Seaweeds of the British Isles Volume 2 by Elsie M. Burrows.

Subject to verification Percursaria percursa (C.Agardh) Rosenvinge, 1893 may be transferred to Ulva, as Ulva percursa (C.Agardh) C.Agardh. Neither WoRMS or Algaebase lists the change but the book Seaweeds of Britain and Ireland Second Edition reports the species as Ulva percursa, 11.10.17.'' Currently Percursaria percursa is accepted on the NBN, therefore records should be sent as such.

AlgaeBase is a database of information on algae that includes terrestrial, marine and freshwater organisms.

The main objective of this website is in furthering environmental awareness and education through the medium of photography. To increase awareness and access to the wildlife of the region and help

people find and identify it. Sometimes the difference between species is obvious but many species can only be determined by observing microscopic characteristics that are specific to any one species.
