Pan44^T, a novel strain belonging to the phylum Planctomycetes, was isolated from a red biofilm in a hydrothermal area close to the island Panarea in the Tyrrhenian Sea north of Sicily, Italy. The strain forms white colonies on solid medium and displays the following characteristics: cell division by budding, formation of rosettes, presence of matrix or fimbriae and long stalks. The cell surface has an interesting and characteristic texture made up of triangles and rectangles, which leads to a pine cone-like morphology of the strain. Strain Pan44^T is mesophilic (temperature optimum 26 °C), slightly alkaliphilic (pH optimum 8.0), aerobic and heterotrophic. The strain has a genome size of 6.76 Mb with a G + C content of 63.2%. Phylogenetically, the strain is a member of the family Planctomycetaceae, order Planctomycetales, class Planctomycetia. Our analysis supports delineation of strain Pan44^T from all known genera in this family, hence, we propose to assign it to a novel species within a novel genus, for which we propose the name Caulifigura coniformis gen. nov., sp. nov., represented by Pan44^T (DSM 29405^T = LMG 29788^T) as the type strain.

Pan44 ^T是一种属于浮球菌门的新菌株，是从意大利西西里岛北部第勒尼安海 Panarea 岛附近热液区的红色生物膜中分离出来的。该菌株在固体培养基上形成白色菌落并表现出以下特征：细胞通过出芽分裂、形成玫瑰花结、存在基质或菌毛和长茎。细胞表面具有由三角形和矩形组成的有趣且特征性的纹理，这导致该菌株具有松果状形态。应变 Pan44 ^T嗜温（最适温度 26 °C）、微嗜碱（最适 pH 值 8.0）、需氧和异养。该菌株的基因组大小为 6.76 Mb，G + C 含量为 63.2%。系统发育，该菌株是家族的一个成员Planctomycetaceae，为了Planctomycetales，类Planctomycetia。我们的分析支持从该家族中的所有已知属中划定 Pan44 ^T菌株，因此，我们建议将其分配给新属中的一个新物种，为此我们建议将其命名为Caulifigura coniformis gen。十一月，sp。11 月，以 Pan44 ^T (DSM 29405 ^T  = LMG 29788 ^T ) 为典型菌株。
