County Recorder: Dr. Hilary Belcher
Very little work has been done on this group apart from the Stoneworts (Characae) which are recorded by some botanists. A start has been made on producing a County checklist. Intricate Tolypella has been included in the County BAP and a site for the species in the County has been designated as a County Wildlife Site.
