The flora of Reticulariaceae of central Argentina country region is revised in the frame of a Catalogue of Argentinean Myxomycetes. Herbarium materials from CORD* and LIL* from Córdoba and Tucumán provinces were studied. Macroscopic sporocarps were observed with photonic stereo-microscope and microscopic peridium, pseudocapillitium and spores were analyzed using transmission-microscope. Material were mounted in 3% KOH and stained with lactophenol cotton blue and aqueous floxina. The structures colors were named with spanish alive words and following Ridgway (1912) colors table. Species identification, names and synonymies were according Alexopoulos & Martin (1969). An artificial dicotomic key were made to discrimine all species analyzed. Four genera and 5 species are recognized, described and illustrated: 2 are new records for Córdoba province: Dictydiaethalium plumbeum, Enteridium lycoperdon and 1 for Tucumán (Tubifera microsperma); the distribution area of Lycogala epidendrum and L. flavofuscum is enlarged in Córdoba province.
