Notes     (Last Modified On 5/12/2009)
general taxon notes:

 Tuomikoski and Koponen (1979) considered Calliergon stramineum to be rather different from the rest of the species of Calliergon both gametophytically and sporophytically, and they treated it in the separated subgenus, Calliergon subgen. Straminea. Hedenäs (1993) later elevated it to the genus level as Straminergon. Although the genus has been recently accepted by Buck and Goffinet (2000), and was placed in the family Campyliaceae W. R. Buck, we prefer placing this species in Calliergon here in a traditional framework of the Amblystegiaceae.
