摘要对四分孢子囊的发育和解剖学研究表明，海绵和水生孢子是珊瑚科珊瑚亚科(红藻门)的不同属。在澳大利亚种群中，四孢子囊孔道由一环明显的细长细胞排列而成，这些细胞由散布在孢子囊中的细丝组成，不伸入孔道内，与屋顶表面大致垂直。在海绵的模式物种--海绵果树中，孔道由外围屋顶细丝形成的细胞排列而成，突出到孔道中，方向与屋顶表面大致平行。雷氏水生动物和孔虫的四分孢子囊发育。
Abstract Studies of tetrasporangial conceptacle development and anatomy have led to the conclusion that Spongites and Hydrolithon (of which Porolithon is considered to be a heterotypic synonym) are distinct genera of the Corallinaceae (Rhodophyta). In Australian populations of Hydrolithon reinboldii (Weber van Bosse et Foslie) Foslie, the type species of Hydrolithon, and Porolithon onkodes (Heydrich) Foslie, the type species of Porolithon, the tetrasporangial conceptacle pore canal is lined by a ring of conspicuous, elongate cells that arise from filaments interspersed amongst sporangial initials, do not protrude into the canal, and are oriented more or less perpendicularly to the roof surface. In Spongites fruticulosus Kutzing, the type species of Spongites, the pore canal is lined by cells that arise from peripheral roof filaments, protrude into the canal and are oriented more or less parallel to the roof surface. Tetrasporangial conceptacle development in Hydrolithon reinboldii and Porolithon onkodes i...
