He served as director of the journal Revue mycologique.[1] His collections of fungi are included in several exsiccatae,[2] including "Fungi (selecti) Gallici exsiccati" and "Fungi selecti exsiccati"[3][4] with publications.[5][6] His collection of algae is part of the exsiccatae series: "Algues de France", which he co-edited since 1883.[7][8]
