While science-based education is widespread for macroscopic flora and fauna, the microscopic world has received much less attention. In 2015, having the aim of establishing a tradition, the Phycological Forum announced its first “Alga of the Year” in form of an online voting. The three candidates of algae were Didymosphenia geminata , Haematococcus pluvialis and Prymnesium parvum , from which the Haematococcus pluvialis received the overwhelming majority of votes. Introducing the ecological and economical aspects and distribution of the candidate taxa in Hungary, we aimed at to stress that there is a high educational potential of microscopic life. Furthermore, our study draws the attention to the fundamental role of algae in aquatic ecosystems, stressing their importance in maintaining life.
