4. ‘ Biddulphia dalmatica’

One BM slide indicates the presence of a species provisionally named ‘ Biddulphia dalmatica’, an unpublished herbarium name: BM 19396 (‘Kützing 822’, Adriatic, Dalmatica, Croatia, BM001167212: https://data.nhm.ac.uk/dataset/collectionspecimens/resource/05ff2255-c38a-40c9-b657-4ccb55ab2feb/record/8288390). This slide has no coverslip and inspection of the mica for ‘Kützing 822’ reveals only a few fragments, so no SEM work was attempted ( Fig. 20 ).
