The operculum or lid removed from the sporangium, showing it to be destitute of a peristome. The outer peristome usually exhibits a number of broad, short, lanceolate processes called teeth, and the inner is developed into long filamentous cilia (cUium, an eyelash). Sometimes there is only one peristome or fringe, or the membrane, instead of being developed into teeth or ciliae, may stretch across the mouth of the sporangium and close it altogether, as in the genus Atriohium; or, perhaps, neither of the membranes is developed, and the sporangium is without a peristome, as in the genus Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Coultas, Harland, d. 1877; Stifle, Cloyd B. sgn.
