The sporogonium is very similar throughout the group (figs. 8, 9).

Certain cells in the sporogonium of a moss are called mother-cells.

In contrast to the sexual generation this stage is called the spore-bearing generation (sporogonium, sporophyte).

Fertilization takes place about June, and the sporogonium is fully developed by the winter.

In none of the liverworts does the sporogonium develop by means of an apical cell, as is the rule in mosses.
