Popis: Fontinalis is well known for its rarity in producing spores. First, this is a dioicous moss – its males and females are separate plants (Figure 1 and Figure 2). It lives in the water, often fast-moving water. When the sperm leave the antheridium, they are faced with a flowing medium. Since the male plant most likely got where it is by a fragment lodging against a rock, it is likely that all the neighbors are males too. These tiny sperm must brave the big waters of the stream to locate a female. Then they must stop at just the right place so they can swim against the current to reach the archegonium. Or not.
