[3] This moss can be identified from other members of the Plagiomnium genus by dark coloured stomata guide cells and the absence of sterile stems.

[4] Majority of the Plagiomnium venustum species have been recorded in British Columbia, Canada and Oregon, United States, making it a Pacific Coast Bryophyte.

[9] The sporangial jacket contains mammillose stomata guard cells that are easily visible because of their dark colour.

[2] P. venustum is a unique species out of all the Plagiomnium moss because of the following characteristics: It has dark coloured stomatal guide cells, densely twisted leaves around the stem when they are dry, collenchymatous lamina cells, a distinct brown and wrinkled capsule neck, and absent sterile stems.

[10] The perichaetial leaves are assembled into a rosette and have a distinct yellow midrib with multiple emerging sporophytes.

The leaves of these mosses are green and generally erect and are shaped obovate or elliptic with unistratose leaf margins.

The sporangia are nodding due to a bent seta with a capsule, operculum, and arthrodontous exostome and endostome teeth.

[12][13] Based on these statistics, BC has also assigned P. venustum to the "Yellow" List, which means that this species is at the least risk of being lost.
