Calliergonella Loeske, 1911.

Our one species of Calliergonella is an important lawn weed in moist coastal areas of the state. Similarly, it grows in wetlands especially after disturbance. It is an ecostate pleurocarpous moss whose leaves are bluntly rounded at the apex. Especially useful in field recognition is the fusiform shape of the apical bud, a feature not so well shown by any other local bryophyte. It should be noted here that Hypnum lindbergii Mitten has been placed in the otherwise monotypic genus, Calliergonella. We are not comfortable with such a placement and continue to treat it as a Hypnum.
