Nectriaceae is a highly diverse family, and members have a worldwide distribution, particularly in warm temperate to tropical regions. During the survey of fungal diversity in different habitats in Yunnan province, China, two new species isolated from soil and air respectively, namely and , were proposed based on morphological comparisons and the multi-gene phylogenetic analyses of combined ITS, LSU, 2, and 2 sequence data. Phylogenetically, both species clustered in a monophyletic clade within Nectriaceae with strong support. is characterized by synnematous conidiophores, pale olivaceous-green, clavate to oblong-ellipsoidal, multi-septate conidia, and pale olivaceous-green chlamydospores. has acremonium-like or penicillium-like conidiophores and either obovate or ellipsoidal, cylindrical or fusiform conidia. Full descriptions, illustrations, and a phylogenetic tree showing the phylogenetic position of the two new species were provided.
肉座菌科是一个高度多样化的科，其成员分布于世界各地，尤其在暖温带至热带地区。在中国云南省不同生境的真菌多样性调查中，基于形态学比较以及ITS、LSU、28S和TEF1-α序列数据的多基因系统发育分析，分别从土壤和空气中分离出两个新物种，即[物种名称1]和[物种名称2]。在系统发育上，这两个物种都聚集在肉座菌科内的一个单系分支中，得到了有力支持。[物种名称1]的特征是有束状分生孢子梗、浅橄榄绿色、棒状至长椭圆形、多隔膜的分生孢子以及浅橄榄绿色的厚垣孢子。[物种名称2]有枝顶孢属样或青霉属样的分生孢子梗，分生孢子为倒卵形或椭圆形、圆柱形或梭形。文中提供了这两个新物种的完整描述、插图以及显示其系统发育位置的系统发育树。
