This is the first study exclusively dedicated to the study of Hebeloma in Greenland. It is based on almost 400 collections, the great majority of which were collected by three of the co-authors over a period of 40 years and were lodged in the fungarium of the Natural History Museum in Copenhagen. The material was identified using molecular and morphological methods. In total, 28 species were recognized, 27 belonging to three sections, H. sects Hebeloma, Denudata and Velutipes. One species sampled was new to science and is here described as H. arcticum. For all species, a description, a distribution map within Greenland and macro and microphotographs are presented. A key is provided for the 28 species. The distribution of species within Greenland is discussed. The findings are placed in the context of studies of arctic and alpine Hebeloma from other parts of the world where comparable data exist. Notably, H. grandisporum, H. louiseae and H. islandicum, previously only known from Romania, Svalbard, Iceland or Norway, respectively, have been found in Greenland. The latter is also the only species encountered that does not belong to any of the above sections. Hebeloma excedens and H. colvinii – for the latter we here publish the first modern description – are to date only known from continental North America and now Greenland.

格陵兰Hebeloma（Hymenogastraceae）的调查

这是第一项专门研究格陵兰Hebeloma的研究。它基于近400种收藏，其中大部分是三位合著者在40年的时间内收藏的，并存放在哥本哈根自然历史博物馆的真菌馆中。使用分子和形态学方法鉴定了该物质。总共识别出28种，其中H.宗Hebeloma，Denudata和Velutipes属于3个科。采样的一种物种是科学新事物，在这里被称为H. arcticum。对于所有物种，都有描述，格陵兰岛内的分布图以及宏观和显微照片。提供了28个物种的密钥。讨论了格陵兰岛内物种的分布。这些发现是在存在可比数据的世界其他地区进行的北极和高山Hebeloma研究的背景下进行的。值得注意的是，格陵兰发现了以前仅分别从罗马尼亚，斯瓦尔巴特群岛，冰岛或挪威知道的H. grandisporum，H。louiseae和H. islandicum。后者也是遇到的唯一不属于上述任何部分的物种。Hebeloma excedens和H. colvinii –对于后者，我们在这里发布了第一个现代描述–迄今为止仅从北美大陆到现在的格陵兰岛为人所知。后者也是遇到的唯一不属于上述任何部分的物种。Hebeloma excedens和H. colvinii –对于后者，我们在这里发布了第一个现代描述–迄今为止仅从北美大陆到现在的格陵兰岛为人所知。后者也是遇到的唯一不属于上述任何部分的物种。Hebeloma excedens和H. colvinii –对于后者，我们在这里发布了第一个现代描述–迄今为止仅从北美大陆到现在的格陵兰岛为人所知。
