Desmid new to British Isles found in Clashmore Quarry

February 2nd 2016

Desmid new to British Isles found in Clashmore Quarry. 

On 13th April 2015 I collected a sample of desmids from the large pool in Clashmore Quarry (NC036316) for an old friend, David Williamson, the British expert on these microscopic algae.  The sample proved to be quite rich, and amongst the 38 forms identified by David was one, Closterium macilentum var.substriatum, new to the British Isles.   This paper, in the Quekett Journal of Microscopy, describes the new variety and is illustrated by David’s fascinating drawings.
