Photographed by Bill Ells, UK
Fig.1 is a slide by W.A. Firth of the genus Asteromphalus. You will not be surprised to learn the species name is arachne. Fig.2 is a slide by J.D. Möller of Triceratium. Möller is well known for his type slides of diatoms mounted between the years 1886-1890 including the 'Universum Diatomacearum Moellerianum', Diatom Type Plate with 4026 species, varieties and forms completed in April 1890.
I am very grateful to Barry Miller of the USA for the information on J.D. Möller.
