The Fourth International Chrysophyte Symposium was held in Denmark, at Magleâs Conference Centre in the village of Hosterkob, 20 km North of Copenhagen, 22 - 27 May, 1995.

22 chrysophyte researchers took part, from 11 different countries. The programme included lectures, posters, excursions and microscope work. 20 contributions were given, three of them by invitation, by L.S. Péterfi (Rumania), J.L. Wee (U.S.A.) and R. Wetherbee (Australia).

The topics covered were mainly taxonomy, including molecular studies, ecology, including paleoecology, biogeography, and ultrastructure, of chrysophytes.
