TL;DR: Cytological data for Gymnostomum aeruginosum, Discelium nudum and Plagiomnium ellipticum supplement earlier records from Britain and elsewhere but those for Physcomitrium sphaericum are the first for the species.
Abstract: Cytological data for Gymnostomum aeruginosum (n = 13), Discelium nudum (n = 13) and Plagiomnium ellipticum (n = 6) supplement earlier records from Britain and elsewhere but those for Physcomitrium sphaericum (n = 26) are the first for the species. Chromosome counts continue to have a role to play in bryophyte cytotaxonomy as a means of identifying probable erroneous reports. It is considered, however, that karyotype definition in terms of Giemsa C-banding and cytogenetic studies related to chromosome behaviour have greater taxonomic potential.

TL;DR: The presence of the haplolepideous pattern in Discelium fills an enigmatic gap between the earliest-diverging arthrodontous lineage Diphysciaceae and the terminal lineages Dicranidae, and Bryideae, in which it appears only as a transitional stage towards the more complex structure.
