Digitisation News

A project funded by The Pilgrim Trust digitized over 7000 images, approximately half of the Desmid section of the Fritsch Collection. Funds are being sought to complete online access.

We are always grateful for news of taxa and for reprints on algal taxonomy, especially those with new species.
