Introduction.Physcomitrium eurystomumis rare in Europe and threatened with extinction. This study investigates its status and ecology in Britain.Methods. A detailed search was made forP. eurystomumat all sites where it has been reported in Britain, plus four other locations nearby. Geographic coordinates of colonies were recorded with GPS units and used to derive counts of occupied Ordnance Survey (OS) grid cells at resolutions of 1, 10 and 100 m. DNA barcoding was used to help identify non-fruiting plants. Habitat and community composition were recorded by relevés.Results. In this studyPhyscomitrium eurystomumwas found at five locations, one in Hertfordshire and four in West Norfolk, and occupied 109 OS 1 m grid cells. A small pond in West Norfolk (Wicken Pond) supported the majority (61%) of the population. DNA barcoding helped confirm its occurrence at Wilstone Reservoir (Hertfordshire), at which it was thought extinct. The moss occured exclusively within the drawdown zone of seasonally fluctuating freshwater bodies, both natural and artificial. Vegetation was dominated by vascular plants, most frequentlyAgrostis stolonifera, Persicaria lapathifolia, Ranunculus sceleratus, Rorippa palustrisandStellaria aquatica. Soil pH varied from strongly acidic to slightly alkaline.Conclusions. Unsuccessful searches of five sites with historic records raises concern for the species. The significant importance of Wicken Pond has not been recognised previously and suggests statutory protection of the site is warranted. The non-native and invasiveCrassula helmsiiis a major risk toP. eurystomumat sites in Britain and elsewhere in Europe.
