Abstract
A new species of Hydnum subgenus Rufescentia is described based on collections made in Canada (New Brunswick, Newfoundland and Labrador) and the USA (New York). The new species is found in conifer dominated forests (e.g. Abies, Picea) and occurs in bryophyte-covered (Sphagnum, Bazzania) soil. It differs from the ecologically similar H. quebecense in the duller brown colors of the basidiomes, the smaller basidiospores and the basidia predominantly with three or four sterigmata. Phylogenetic analysis of the ITS region place H. subconnatum and H. oregonense as the closest relatives of H. atlanticum, but these taxa differ in the larger basidiospores, number of sterigmata per basidium, caespitose growth and/or geographic distribution.

根据在加拿大（新不伦瑞克省、纽芬兰省和拉布拉多省）和美国（纽约州）采集到的样本，描述了 Hydnum 亚属 Rufescentia 的一个新物种。该新物种生长在针叶林（如：Abies、Picea）中，并生长在被苔藓植物（Sphagnum、Bazzania）覆盖的土壤中。与生态学上相似的 H. quebecense 的不同之处在于基生体色较暗，基生孢子较小，基生体主要有三或四个柱头。ITS区域的系统发育分析表明，H. subconnatum 和 H. oregonense 是 H. atlanticum 的近亲，但这些类群在较大的基生孢子、每个基生体的立体体数量、丛生生长和/或地理分布方面存在差异。引用：Justo A, Hood AW, Swenie RA, Matheny PB (2023).Hydnum atlanticum, a new species from Eastern North America.真菌系统学与进化 11: 63-70. doi: 10.3114/fuse.2023.11.05.
