A significant northward extension of the areaof <I>Aloina bifrons</I> in Europe (Bryophyta, Pottiaceae)

Aloina bifrons (De Not.) Delgad. is recorded for the first time in France in the Limagne, Puy-de-Dôme department, Auvergne region. This is a significant northward extension of the species\u27 known range. It grows there on sunny marlaceous lime with gypsum traces on a south-facing steep slope. The French habitat differs significantly from the situation recorded in other parts of the Mediterranean and Irano-Turanic areas, where Aloina bifrons is a typical inhabitant of gypsum soils with a rich assemblage of Xeropottioid elements.
