Identification of algae

Identification of marine, freshwater and terrestrial algae requires considerable specialised expertise and close examination of fresh and fixed material; some entities require culturing and extraction of DNA for sequencing. We do not provide such a service, and we can no longer respond to such enquiries. Please do not ask for identification of pictures or samples of algae. We are very sorry, but we have to spend our limited time on the data, not answering large quantities of unsolicited e-mails.
