Two new species in the genus Auritella (Inocybaceae) are described as new from tropical rainforest in Cameroon. Descriptions, photographs, line drawings, and a worldwide taxonomic key to the described species of Auritella are presented. Phylogenetic analysis of 28S rDNA and rpb2 nucleotide sequence data suggests at least five phylogenetic species that can be ascribed to Auritella occur in the region comprising Cameroon and Gabon and constitute a strongly supported monophyletic subgroup within the genus. Phylogenetic analysis of ITS data supports the conspecificity of numerous collections attributed to the two new species as well as the monophyly of Australian species of Auritella. This work raises the known number of described species of Auritella to thirteen worldwide, four of which occur in tropical Africa, one in tropical India, and eight in temperate and tropical regions of Australia. This is the first study to confirm an ectomycorrhizal status of Auritella using molecular data.

喀麦隆的金龟科新物种，对已知物种具有世界范围的钥匙。

喀麦隆的热带雨林描述了奥里氏藻属（Inocybaceae）中的两个新物种。介绍了描述的物种，描述，照片，线条图以及描述的金龟属物种的全球分类学关键。对28S rDNA和rpb2核苷酸序列数据的系统进化分析表明，至少有5种可归因于Auritella的系统发生种出现在包括喀麦隆和加蓬在内的区域内，并构成该属内一个有力支持的单系统亚组。ITS数据的系统发育分析支持归因于这两个新物种以及澳大利亚奥利氏菌属单一物种的众多收藏的同质性。这项工作将已知的奥氏杆菌的已知数量增加到全世界的13种，其中4种发生在热带非洲，一种在印度热带，八个在澳大利亚的温带和热带地区。这是首次使用分子数据确认金盏花的外生菌根状态的研究。
