Cosmarium luxuriosum var. papilliformis  Williamson & Johnson

Cosmarium luxuriosum was first described as a forma of Cosmarium margaritiferum in 1988 and a year later Coesel raised it to species level. In 2021 David Williamson discovered several cells of this species with a large central granule, from a sample collected from South Uist. Chris Johnson also subsequently found it. It has been proposed as a new variety
