Bryum pseudotriquetrum Bryum neodamense Hodgetts et al. (2020): Ptychostomum neodamense has been shown by Holyoak and Hedenäs (2006), from molecular and other data, to represent an inconstant phenotype of Ptychostomum pseudotriquetrum occurring locally in highly calcareous habitats prone to inundation, and connected to it by intermediate forms known widely in Europe and also in Asia, Alaska and Greenland. Its retention at species rank by Spence (2014) is a consequence of an over-emphasis on morphological data.Holyoak and Hedenas (2006) do not consider P. neodamense a good species. B. neodamense is an inconstant phenotype of B. pseudotriquetrum, which occurs very locally in highly calcareous habitats that are subject to periodic inundation. Also, variety neodamense is not combined with Ptychostomum pseudotriquetrum. Bryum neodamense was considered as Vulnerable in Finland in 2010 Red List assessment.
