A revision of the late Mississippian (late Viséan-early Serpukhovian) cyanobacterial and algal assemblages of Montagne Noire (Aude-Hérault, France) is undertaken, mainly based on new data recently obtained with the foraminiferal assemblages of this area. In this taxonomic contribution, one tribe Borlatellae trib. nov. is translated, and three new genera Ortonellopsis gen. nov., Anchisolenopora gen. nov. and Neoradiosphaeroporella gen. nov., and four new species of algae are described: Ortonellopsis laxa gen. et sp. nov., Anatolipora macroporelloidea sp. nov., Paraepimastopora somervillei sp. nov., and Neoradiosphaeroporella aprica gen. et sp. nov. In the Algospongia (incertae sedis algae), the genera Zidella, Valuzieria emend. herein and Asteroaoujgalia are revised. Most of the species appear to be restricted to the latest Viséan-early Serpukhovian interval in the Montagne Noire, and thus, they have to be investigated in coeval Tethyan and Uralian areas for their possible biostratigraphic importance.

Field work of D.V. and P.C. was funded by the Spanish Ministerio de Economía y Competitividad (research project CGL2012-30922BTE).
