Two novel Gram-stain-negative, aerobic strains (ZXM100T and ZXM098) were isolated from seawater in the coastal region of Qingdao (36.027° N 120.184° E), China, during a massive green algae bloom. Cells were ovoid to irregular short rods and lacked flagella. Poly-β-hydroxybutyrate was accumulated. Cells did not contain bacteriochlorophyll a. The isolates grew at NaCl concentrations of 3–9 % and 22–28 °C. C18 : 1ω7c, C18 : 0 and C16 : 0 were the major fatty acid components. The polar lipids of ZXM100T were phosphatidylglycerol, phosphatidylethanolamine, phosphatidylcholine, a single lipid and an unidentified aminolipid. The predominant isoprenoid quinone of ZXM100T was Q-10. Phylogenetic analysis based on 16S rRNA gene sequences showed that strains belonged to the family Rhodobacteraceae . Based on the results obtained in this study, strain ZXM100T was considered to represent a novel species in a new genus, for which the name Lentibacter algarum gen. nov., sp. nov. is proposed. The type strain is ZXM100T ( = LMG 24861T = CGMCC 1.10234T); the DNA G+C content of the type strain is 54.6 mol%.

Storeacolumnella hudsonensis is described as a new genus and species of encrusting, colonial organism that lived in an intertidal, rocky-shore environment. The fossil was discovered in the basal beds of the Upper Ordovician Port Nelson Formation at a coastal outcrop on Hudson Bay near Churchill, Manitoba. Showing some possible characteristics of sponges and other possible characteristics of calcaerous green algae, this matlike organism is considered nonetheless to have uncertain taxonomic affinities. It consists of cylinder-shaped columns, each with an internal system of star-shaped filaments or spicules as viewed in transverse section. The cylinders stand vertical in longitudinal section and are densely packed together to form a mat. The hard substrate to which the mat is attached consists of a boulder eroded from the Precambrian Churchill Quartzite. Maximum colony size observed in a single example exhibits a diameter of not less than 80 mm and maximum thickness of 5.85 mm.

Anatoliacodiumgen. nov. (Halimedaceae, Green algae) from the Ilerdian-Cuisian in the Eskişehir region (Western Central Turkey)A new genusAnatoliacodium(Halimedaceae, Green algae) is described from the Ilerdian-Cuisian shallow-water sediments of Eskişehir region, central-western Turkey. These sequences consist of limestones, clayey limestones, sandy limestones and claystones.Anatoliacodiumgen. nov. is characterized by erected calcareous segments with well differentiated inner structure: prevailing with large medulla of more or less densely set parallel filaments and cortical zone of prevailing horizontal to subhorizontal cortical filaments, once branching and without constriction. It is supposed that poorly and rarely preserved noncalcareous structures on the skeleton surface could be reproductive structures. The type species of the new genus isAnatoliacodium xinanmuigen. nov. sp. nov. A further new species is also described:Anatoliacodium mericigen. nov. sp. nov. FinallyGymnocodium nummuliticumPfender, 1966 is emended and transferred to the genusAnatoliacodium.

An enigmatic encruster from the Upper Ordovician rocky shore exposed near Churchill, Manitoba, was recently described by Johnson et al. (1998). The specimen was found attached to a quartzite boulder enclosed in carbonate matrix. The matlike, calcareous fossil consists of densely packed, vertical, cylindrical columns with upward-radiating structures issuing from their centers. It was identified as a new genus and species, Storeacolumnella hudsonensis, of uncertain taxonomic affinity but with possible characteristics of sponges and calcareous green algae. In particular, the radiating structures within columns were compared with spicules of a sclerosponge and with the siphon system of siphonous green algae.
