A new lichen species is described from specimens growing on Fraxinus trees north of Eindhoven (the Netherlands). Morphological and genetic studies suggest that the new species belongs in the genus Catillaria, and the name Catillaria flexuosa is proposed because of its flexuose apothecia. The new species is characterized by the relatively large apothecia (up to 0.9 mm diam.) and relatively thick, knobby to ±subsquamulose, greenish, thallus. Due to their similar morphological features, C. flexuosa can be easily confused with Catillaria chalybeia, C. fungoides or C. nigroclavata, so it is therefore compared with these species. In addition, Arthonia epiphyscia is reported being a very rare species in the Netherlands.

Catillaria flexuosa（Catillariaceae），一种来自荷兰的新地衣物种

从生长在水曲柳埃因霍温（荷兰）北部的树木。形态学和遗传学研究表明新种属于该属卡提利亚, 和名字屈曲卡提利亚被提议是因为它的柔韧的 apothecia。新种的特点是子囊相对较大（直径可达 0.9 毫米）和相对较厚，多节到 ± 次鳞片状，绿色，菌体。由于它们相似的形态特征，C. flexuosa很容易与卡提利亚 chalybeia,蕈类要么C. nigroclavata，因此它与这些物种进行比较。此外，刺槐骨骺据报道，在荷兰是一种非常稀有的物种。
