ABSTRACT Introduction. The tiny moss Microhypnum sauteri is widely distributed in Europe being recorded from 14 countries, but it seems to be relatively uncommon everywhere and is on the Red List in seven of these countries. The sites in Norway are the closest populations to this new find in Scotland. Methods. A specimen was collected during a visit to Assynt in West Sutherland in April 2019, during a survey of populations of Amblyodon dealbatus and Encalypta alpina, and subsequently identified as Microhypnum sauteri. Results. Micrcohypnum sauteri is reported from the limestone at Inchnadamph in West Sutherland, new to the British flora. The species and its habitat are described and comments made on its ecology and European distribution. Conclusions. The site where Micrcohypnum sauteri was found has a number of other montane calcicole species and M. sauteri is most likely to be native here. Given its small size and the fact that it has been overlooked at such a well-known site, it seems quite possible that it could occur on calcareous rocks in the mountains elsewhere in Scotland, some other possible locations being the high limestone in the Alder Forest and in the Glenshee area and perhaps on the calcareous schist on Ben Lawers.

Microhypnum sauteri (Schimp.) Jan Kučera 和 Ignatov 在西萨瑟兰，英国植物群的新成员

摘要介绍。微小的苔藓 Microhypnum sauteri 在欧洲广泛分布，有 14 个国家有记录，但似乎到处都比较少见，其中有 7 个国家被列入红色名录。挪威的遗址是最接近苏格兰这一新发现的种群。方法。在对 Amblyodon dealbatus 和 Encalypta alpina 种群进行调查期间，于 2019 年 4 月访问 West Sutherland 的 Assynt 期间收集了一个标本，随后被确定为 Microhypnum sauteri。结果。据报道 Micrcohypnum sauteri 来自西萨瑟兰 Inchnadamph 的石灰岩，这是英国植物群的新成员。描述了该物种及其栖息地，并对其生态和欧洲分布发表了评论。结论。发现 Micrcohypnum sauteri 的地点有许多其他山地钙质物种，而 M. sauteri 最有可能是这里的原生物种。鉴于它的体积很小，而且在如此著名的地点被忽视了这一事实，它似乎很有可能发生在苏格兰其他地方山区的钙质岩石上，其他一些可能的位置是阿尔德森林的高石灰岩在 Glenshee 地区，也许在 Ben Lawers 的钙质片岩上。
