We have recently databased and imaged selected genera of British Algae held in the herbarium as part of a project run by the Natural History Museum, London. The aim of this project is to gather data of interest to biodiversity and conservation research including non-native seaweeds, species of conservation concern and species which may be potential indicators of environmental change.

During this process we came across some interestingly mounted and beautiful specimens, a selection of these are shown below:
Drachiella spectabilis certainly deserves the epithet spectabilis! It has kept a wonderful hot pink colour since it was collected in 1978
This button is the hold fast of Himanthalia elongata
How do you mount a specimen of Chorda filum that is a couple of metres long?
Phymatolithon calcareum is a coralline red alga, stored in boxes, mounted on specimen sheets.
This specimen of Alaria esculenta is a larger seaweed, and has had to be curved to fit the space on the sheet.
This ‘furry worm’ is Chorda tomentosa
This species, Padina pavonica is known as Peacocks tail, the resemblance can still be seen in the dried specimens
Sphaerococcus coronopifolius has a lovely branching form, as well keeping its red and pink colour since it was collected in 1829
