Specimens were found growing with the marine lichen Lichina pygmaea, at Battery Rocks, Penzance, Cornwall. 26.04.16.
Identification made using a microscope and Seaweeds of the British Isles Volume 2 by Elsie M. Burrows.
On looking at ERICA, the Cornish records database I found three very old records for this species, two were from Penzance, and one, a 1880 record was also from Battery Rocks, Penzance. An earlier record, November 1839, was by J. Ralfs, at Penzance.
This is certainly an under-recorded species because of the need for microscopic identification. Fine green algal species can also grow together as a colony so more than one species could be involved, here the specimen taken was growing with Blidingia minima.
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.
