The spore capsule, often with a supporting stalk (called a seta), is the sporophyte and this grows from the gametophyte stage. You will commonly see the statement that a moss gametophyte consists of leaves on stems. That statement is so close to the whole truth that it's no surprise it's so commonly used.When a moss spore germinates it first develops a protonema.This is a filamentous to sheet-like growth form, often with a strong resemblance to an algal colony or a fern prothallus. In due course one or more stems grow from the protonema and leaves develop on the stems, giving rise to one or more leafy-stemmed plants.n almost all moss species the capsule has a well-defined mouth at the end opposite the stalk or the point attaching the capsule to a stem. When there is a mouth, the spores are released through that mouth. There is a very small number of mouth-less mosses-such as species of the genus Andreaea.
