摘要

黄柏是一种全球分布的有刺水螅类真菌属,由白色孢子印和外生菌根生命策略识别。在欧洲,许多黄柏物种种群数量下降,被用作具有高保护价值的森林指标。然而,根据IUCN的指导方针,它们在这一背景下的使用以及对其灭绝风险的正确评估目前受到不一致的名称使用和不明确的物种划分的阻碍,主要是在P. melaleucus, P. niger和P. tomentosus的物种复合中。我们分析了白鹭的286个ITS序列,其中51个也与相应的LSU区域结合进行了分析。这项工作包括102个新测序的集合,主要来自瑞典和英国。我们的系统发育结果表明,四个物种是科学上的新物种,因此我们正式将P. castaneoleucus描述在P. melaleucus形态复合体中,P. aquiloniniger和P. frondosoniger描述在P. niger复合体中,P. dititomentosus作为P. tomentosus的姐妹种。P. melilotinus的组合是为了容纳一个额外的,以前描述过的,属于P. niger复合体的物种。我们指定了千层棘球蜂、黑棘球蜂和毛毛棘球蜂的选型和表型,并指定了melilotinus的表型。黄柏是欧洲的新物种,黄柏和紫柏的生态幅度比以前认为的要大。我们提供了目前在欧洲已知的所有13种物种的钥匙,并根据北欧国家和英国的数据将它们分配到三个基于栖息地的组合。我们希望这将有助于评估这些生境,以便采取法律保护和其他与保育有关的行动。引文:Svantesson S, Larsson E, Larsson K-H, Parfitt D, Suz LM, Ainsworth AM(2025)。欧洲香栓属(香栓科,担子菌科):4个新种、1个新组合、4个新分型和1个欧洲首次记录。真菌分类学与进化15:1-45。doi: 10.3114 / fuse.2025.15.01。

The genus Phellodon (Thelephorales, Basidiomycota) in Europe: Four new species, one new combination, four new typifications and a first European record.

Phellodon is a globally distributed genus of stipitate hydnoid fungi recognised by a white spore print and an ectomycorrhizal life strategy. In Europe, many Phellodon species have declining populations and are used as indicators of forests with high conservation values. However, their use in this context and the correct assessment of their extinction risk, according to IUCN guidelines, are currently hampered by inconsistent name usage and unclear species delimitations, primarily within the species complexes of P. melaleucus, P. niger and P. tomentosus. We analysed 286 ITS sequences of Phellodon, of which 51 were also analysed in conjunction with the corresponding LSU regions. This work included 102 newly sequenced collections, primarily sourced from Sweden and the UK. Our phylogenetic results show that four species are new to science and hence we formally describe P. castaneoleucus within the P. melaleucus morphological complex, P. aquiloniniger and P. frondosoniger within the P. niger complex and P. dititomentosus as a sister species to P. tomentosus. The combination P. melilotinus is made to accommodate an additional, previously described, species that belongs in the P. niger complex. We designate lectotypes and epitypes for P. melaleucus, P. niger and P. tomentosus as well as an epitype for P. melilotinus. Phellodon ellisianus is recorded as new to Europe and the ecological amplitude of P. secretus and P. violaceus is revealed to be wider than previously believed. We provide a key to all 13 species currently known in Europe and assign them to three habitat-based assemblages based on data from the Nordic countries and the UK. We hope this will facilitate the assessment of such habitats for legal protection and other conservation-related actions.
