context_page_description: Fissidens adianthoides, the maidenhair pocketmoss, is a moss in the family of Fissidentaceaea. It was first collected by Hedwig in 1801.
  It is found all over North America and even in Greenland and Alaska.
  The Nitinaht First Nations of Vancouver Island used maidenhair moss to bandage wounds. It was named by the Anglo-Saxons because it resembles pubic hair.
context_section_description: A sporophyte is the diploid multicellular stage in the life cycle of a moss which produces spores. They are commonly observed in this species. There is one sporophyte produced per perichaetium. The seta, which is a stalk that supports capsule, is relatively short and is 25 mm in length. It is red-brown in colour and inserted laterally. The operculum (lid) is about the same length as the rest of the sporangium. The capsule of the sporophyte is inclined, curved, bilaterally symmetric and about 1.5 mm. As for the calyptra, it is cucullate, smooth and about 2.5 mm.  The spores are about 3-22 µm.
  Since it is a member of the Bryopsida class it also has arthrodontous peristome teeth which aid in spore dispersal. Fissidens adianthoides have 16 red teeth. Arthrodontous teeth are made up of cell wall fragments. They are also hygroscopic, meaning they move according to changes in humidity. They are about 85–120 μm wide at the base of the teeth and the upper part of the teeth are finely papillose.
