In the year 2001, some conspicuous black stains appeared on the walls of Lascaux Cave in France, which progressively disseminated throughout the cave. These black stains were so evident by 2007 that they have become one of the cave's major problems. In a mycological study of the black stains, Ochroconis strains were abundant among the isolates and constituted the major group of melanised fungi. Two new species of the genus Ochroconis, O. lascauxensis and O. anomala, were isolated and described. The description is based on the morphology of the fungi and the phylogenetic relationships of two of its gene regions internal transcribed spacer (ITS) and RNA polymerase II subunit B (RPB2). In addition, data on their physiology and cellular fatty acid profiles are reported. The development of these species was likely linked to the presence of unusual carbon and nitrogen organic sources provided by the intensive biocide treatments.
2001 年，法国拉斯科洞穴的墙壁上出现了一些明显的黑色污渍，这些污渍逐渐扩散到洞穴的各个角落。到 2007 年，这些黑色污渍变得非常明显，成为洞穴的主要问题之一。在对黑色污渍的一项真菌学研究中，Ochroconis 菌属的菌株在分离物中非常丰富，构成了主要的黑化真菌群体。从该菌属中分离并描述了两种新种，即 O. lascauxensis 和 O. anomala。该描述基于真菌的形态以及其两个基因区域的系统发育关系：内部转录间隔区（ITS）和 RNA 聚合酶 II 亚基 B（RPB2）。此外，还报告了它们的生理和细胞脂肪酸图谱数据。这些物种的出现可能与密集使用杀菌剂所提供的特殊碳源和氮源有关。
