Testate amoebae have been frequently studied by protistologists, but still little information is available on some groups like the Chlamydophryidae. These amoebae are difficult to culture and therefore quantitative information on their morphology, phylogeny and ecology is scarce. We isolated and cultured a small testate amoeba from an agricultural field at Muncheberg near Berlin, Germany. Morphological analyses revealed it to be a new species of the genus Lecythium. We describe Lecythium terrestris sp. nov. and present its morphology, mycophagous and algivorous feeding habits and its ability to form cell aggregates by fusion. Using small-subunit ribosomal RNA gene phylogeny, we could confirm the phylogenetic position of the genus Lecythium among the Cercozoa where it groups closely to Pseudodifflugiidae (Tectofilosida).
