This contribution presents further records of lichenicolous fungi previously unknown from Czechoslovakia. A new species, Polycoccum crassum sp. nov., parasitizing Peltigera lepidophora, is described. Two taxonomic recombinations are proposed: Opegrapha parasitica (Massal.) comb. nov. and Stigmidium eucline (Nyl.) comb. nov. All taxa are briefly described and illustrated, with taxonomic notes.
