Its erect and cylindrical capsules are stegocarpic, not systylius. Its urn measures 1.5-2.7 mm and its peristome 300 μm. Its spherical spores are either very finely papillose or border on smooth, measuring 8-12 μm. [2] The moss can be distinguished from similar mosses by its erect and cylindrical capsule and its "hair-pointed" leaves.
Polytrichum commune (also known as common haircap, [2] great golden maidenhair, [2] great goldilocks, [2] common haircap moss, or common hair moss) is a species of moss found in many regions with high humidity and rainfall. The species can be exceptionally tall for a moss with stems often exceeding 30 cm (12 in) and rarely reaching 70 cm (27.5 ...

The endostome is a more delicate membrane, and its teeth are aligned between the teeth of the exostome. There are a few mosses in the Bryopsida that have no peristome in their capsules. These mosses still undergo the same cell division patterns in capsule development, but the teeth do not fully develop.
Pogonatum urnigerum is a species of moss in the family Polytrichaceae, commonly called urn haircap. [2] The name comes from "urna" meaning "urn" and "gerere" meaning "to bear" which is believed to be a reference made towards the plant's wide-mouthed capsule. [3]
In hornworts, the meristem starts at the base where the foot ends, and the division of cells pushes the sporophyte body upwards. In mosses, the meristem is located between the capsule and the top of the stalk (seta), and produces cells downward, elongating the stalk and elevating the capsule.
The Bryopsida constitute the largest class of mosses, containing 95% of all moss species.It consists of approximately 11,500 species, common throughout the whole world. The group is distinguished by having spore capsules with teeth that are arthrodontous; the teeth are separate from each other and jointed at the base where they attach to the opening of the capsule.

Polytrichum is a genus of mosses — commonly called haircap moss or hair moss — which contains approximately 70 species that have a cosmopolitan distribution. The genus Polytrichum has a number of closely related sporophytic characters. The scientific name is derived from the Ancient Greek words polys, meaning "many", and thrix, meaning "hair".
