Two New Species of the GenusTinocladia Kylin(Chordariales, Phaeophyta) from Yellow Sea Coasts of China

【Abstract】 Two new species of the genus Tinocladia Kylin, T. gracilis sp.nov. and T. microsporangii sp.nov., are described. T. gracilis is characterized by its slender frond, variable size, infrequently branched medullary filaments, and short assimilating filaments with 2-7 cells. T. microsporangii is characterized by its medullary cells which are slightly larger than sub-cortical ones; narrow sub-cortical layer, usually consisting of 4-6 cells and very small unilocular sporangia. The holotypes are deposited at the Herbarium of the Institute of Oceanology, Chinese Academy of Sciences, Qingdao, China.更多还原
