Definition
A cardinal organ part (PO:0025001) that develops from an archegonium (PO:0025126) and is a cap or hood enclosing the sporangium (syn: spore capsule; PO:0025094). Source: ISBN:9780473067304, ISBN:0962073342
Comment
Found in bryophytes. The spore capsule calyptra is a membranous or hairy cap or hood, composed of gametophytic tissue (venter; PO:0030038) that protects the embryonic sporophyte within the archegonium (PO:0025126). In some species, it may persist after the sporophyte develops and gets carried upward as the seta (PO:0030032) elongates. The spore capsule calyptra is usually lost before the spores are released, and its shape can be used for identification purposes.
