A complete catalogue of algal taxa described by Pierre Compère

Background – On the occasion of the 80 ^th anniversary of Pierre Compère, a catalogue of all algal and cyanobacterial taxa he described during his scientific career, was compiled. Methods – This catalogue was assembled through consultation of Compère's numerous publications, database queries and contacts with different herbaria where his types are deposited. Results – Pierre Compère described 123 new algal and cyanobacterial taxa. Most of the species belong to the Bacillariophyta, but he also published taxa in the Cyanobacteria, Chlorophyta, Chrysophyta and Euglenophyta. For each taxon, details on the location of the type specimens are included along with their sample localities, dates and references to the protologues. A selection of pictures and drawings are added to illustrate Pierre Compère's work. One name, Caloneis silicula f. angusta is being formally validated.
