“…Pohlia lutescens was considered to be endemic to Europe, extending northwards from Italy to Scandinavia. It is rather common in England, Wales and Ireland, but rare in Scotland (Smith, 2004;Bezgodov & Ignatova, 2013), and has been recorded from Sweden and Denmark, Poland, Bulgaria, France, Serbia and Slovenia (Ochyra et al, 2003;Bezgodov & Ignatova, 2013;Ros et al, 2013). Pohlia lutescens has also been widely reported on bare soils from Asia (China, Mongolia, Russia and Japan) (Bezgodov & Ignatova, 2013).…”

“…Pohlia lutescens is a small, delicate species, easily recognised by the pale yellow or occasionally light reddish-brown, rounded to ovoid, knobbly rhizoidal tubers and narrow lanceolate leaves with narrow laminal cells (Bezgodov & Ignatova, 2013). Pohlia lutescens was considered to be endemic to Europe, extending northwards from Italy to Scandinavia.…”

“…Also, the rhizoidal gemmae in P. lescuriana and P. melanodon (Brid.) A.J.Shaw are smooth rather than knobbly (Smith, 2004;Bezgodov & Ignatova, 2013 Pseudocrossidium obtusulum is known from a few localities in Europe, North America and Asia (Fedosov & Ignatova, 2006;Zander, 2007). This is the first report of P. obtusulum from the Republic of Buryatia.…”
