The paper deals with the red algae (mainly Corallinaceae) which are the main component of the Middle Miocene (Badenian) Pińczów Limestones, Świętokrzyskie Mts. (Holy Cross Mts.), Central Poland. Algal growth forms characterize the facies of the Pińczów Limestones. Distribution of several red-algal species shows a correlation with two environmental parameters, viz. water agitation and the substrate. A comparison to Tertiary red-algal floras shows that the specific composition of the Pińczów Limestones flora resembles other assemblages from the Middle Miocene of Poland and those of Ukraine, as well as the assemblage from the Oligocene of Northern Italy. In the systematic part of the paper 73 species of 12 genera (Archaeolithothamnium, Palaeothamnium, “Lithothamnium”, Mesophyllum, Lithophyllum, Leptolithophyllum, Titanoderma, Melobesia, Lithoporella, Jania, Corallina, and Karpathia) are described, one of which is new: Leptolithophyllum maslovi sp. n.

Rhodoliths from the Middle Miocene (Badenian) deposits of the Korytnica Basin are analysed in terms of environment-related internal features (symmetry, massiveness, growth forms of algae, borings, algal species composition and distribution). Differences in internal structure and distribution of dominant species in the rhodolith populations from Korytnica and Chomentów reflect environmental differences between the two parts of the Korytnica basin. Dense, symmetrical rhodoliths built frequently of thin thalii, with frequent epibionts and rare borings are typical of the shallower part of the basin (Chomentów). Porous, asymmetrical rhodoliths, built mainly of thick thalli, with less frequent epibionts and common borings prevail in the deeper part of the basin (Korytnica). In the systematic part of the paper 26 species of 7 genera (Archaeolithothamnium, Palaeothamnium, Lithothamnion, Mesophyllum, Lithophyllum, Leptolithophyllum and Titanoderma) are described, 7 of which are for the first time reported from the Polish Miocene.
