Sphagnum bergianum forms dense hummocks in medium to rich fen habitats and is associated with such species as Sphagnum warnstorfii, S. subfulvum, S. subsecundum, S. platyphyllum and S. fuscum. Sphagnum bergianum is quite distinct in the field from its very dark brown color tinged with a deep red as well as its 5-ranked branch leaves. Sphagnum subnitens is colored a light brown and red combination, and has unranked branch leaves. Sphagnum subfulvum has a golden brown color that can be tinged with purple but also has unranked branch leaves. Sphagnum flavicomans is a similar-sized brown species of sect. Acutifolia that overlaps S. bergianum in Newfoundland but it is golden brown, lacks the red tinge and has a longer and narrower branch and stem leaves.
