Notas     (Last Modified On 3/17/2009)
general taxon notes:

 

In some habitats, larger plants of Bryum billarderi are very similar to those of Rhodobryum due to the rosulate habit, but B. billarderi differs from species of Rhodobryum by the distinctly bordered leaf margins, the well-developed stereid cells of leaf costae, and the single sporophyte in each perichaetium.
