Myriotrichia (original) (raw)

Myriotrichia is a genus of brown algae. It forms small, soft, olive-brown tufts on the surface of other plants. Filaments rarely exceed centimetres in length. It may grow by intercalary growth. Its sporangia may contain one or many cavities, and emerge directly from the surface cells; they may form a ring around the main nema. Dedicated photosynthetic machinery may be entirely absent. Its life history consists of alternation of phases; it has isogamous gametes, and dioecious gametophytes. The alga has a small genome with approximately 12 chromosomes.
