Tinguy, H., Hugonnot, V., Stoehr, B. & Bick, F. 2019. Arvernella microclada (Amblystegiaceae) newly reported in Vosges (Alsace, France). – Herzogia 32: 200–208.
Arvernella microclada is reported for the first time in Vosges (France). This constitutes a significant north-eastern extension of its known range by about 400 km. This species could be widely overlooked due to its very minute stature and inconspicuous habit, and it is probably more widespread than currently known. Arvernella microclada is easily confused with many tiny mosses which are mostly taxonomically unrelated, so that the characters allowing a safe identification are emphasized. Details are provided of its habitat characteristics and associated species in Hautes-Vosges.
