Hericium flagellum is a highly host-dependent wood-inhabiting fungus in Europe. Its occurrence is strongly connected to the distribution of silver fir (Abies alba). We analysed available data describing ecological factors, especially habitat, substrate preferences and phenology, which are regarded as drivers of H. flagellum occurrence. We also implemented ecological niche modelling to determine the potential range of the fungus. More than half of H. flagellum records (57%) were found in high conservation value areas, on fallen trunks of silver fir trees. The basidiomata were predominantly recorded between August and late November. Distribution of the tree host, precipitation in the driest month, isothermality and annual mean temperature were the most decisive factors influencing H. flagellum occurrence. We conclude that the disjunctive range at present, the risk of tree host extinction linked to habitat loss, and the limited dispersal of H. flagellum propagules are the main threats to this species.

鞭毛猴鞭毛是欧洲高度依赖宿主的木材真菌。它的出现与冷杉冷杉的分布密切相关。我们分析了描述生态因素的可用数据，特别是栖息地，基质偏爱和物候学，这些因素被认为是H的驱动因素。鞭毛发生。我们还实施了生态位建模，以确定真菌的潜在范围。H的一半以上。鞭毛在高保护价值地区的银杉倒下的树干上发现了记录（57％）。basidiomata主要记录在8月至11月下旬之间。树木的分布，最干燥月份的降水，等温和年平均温度是影响H的最决定性因素。鞭毛发生。我们得出的结论是，目前的分离范围，与宿主栖息地丧失相关的树木宿主灭绝的风险以及H的有限扩散。鞭毛繁殖体是对该物种的主要威胁。
