Triploporella remesi (Steinmann, 1903), dasycladalean green alga from the Tithonian-Lower Berriasian of tramberk (Czech Republic) revisited

The dasycladalean green alga Triploporella remesi (Steinmann) is redescribed based on material collected from the Kotouč quarry near Štramberk (Moravia, Czech Republic), probably corresponding to the type locality. The alga is Tithonian–early Berriasian in age according to the age assigned to the Štramberk Limestone. The new material, in addition to the detailed description of Steinmann, indicates that the short club-shaped calcareous skeleton probably represents the fertile upper part of a far longer club-shaped thallus. The well-developed phloiophorous primary laterals are similar to those of other species of Triploporella in having a proximal cylindrical sterile part followed by a stronger distal cylindrical fertile part. Secondary phloiophorous laterals probably combined to create a cortex at their distal ends. The simple undivided spores inferred by previous authors are shown to be recrystallized cyst containers.Web of Science52339439
