S. Ekman & Tønsberg, a lichenised ascomycete in the family Ramalinaceae (Lecanorales, Lecanoromycetes), is described as new to science. It is distinct from other species of in the combination of mainly three-septate ascospores, a crustose thallus forming distinctly delimited soralia that develop by disintegration of convex pustules and the production of atranorin in the thallus and apothecia. The species is known from the Pacific Northwest of North America, where it inhabits the smooth bark of Alnusalnobetulasubsp.sinuata and . is also a new host for the lichenicolous ascomycete Diederich.
埃克曼氏石耳（S. Ekman & Tønsberg），一种茶渍衣科（茶渍目，茶渍纲）的地衣化子囊菌，被描述为科学上新发现的物种。它与该属的其他物种不同，主要体现在以下组合特征：具三个分隔的子囊孢子、形成明显界限分明的粉芽堆的壳状地衣体，粉芽堆由凸起脓疱的解体形成，以及地衣体和子囊盘中产生黑茶渍素。该物种分布于北美太平洋西北部，生长在阿拉斯加桤木（Alnusalnobetulasubsp.sinuata）和[此处原文缺失一种植物名称]的光滑树皮上。它也是地衣内生子囊菌迪德里希菌（Diederich）的新宿主。
