A new species of Coniochaeta from endotracheal secretion of a preterm neonate, Coniochaeta polymorpha, is described. This anamorphic species is characterized by development of dark brown colonies after 1 week of incubation on culture medium, formation of abundant yeast-like cells and sclerotium-like structures producing discrete, brown, nearly globose phialidic conidiogenous cells and absence of chlamydospores. A combined sequence dataset of the ITS region, partial LSU rDNA, actin and β-tubulin genes sufficiently resolved the unique phylogenetic status of this species. In response to recent changes in the nomenclature for pleomorphic fungi, we transfer the Lecythophora species to Coniochaeta, and propose the following new combinations: Coniochaeta canina, Coniochaeta cateniformis, Coniochaeta decumbens, Coniochaeta fasciculata, Coniochaeta hoffmannii, Coniochaeta lignicola, Coniochaeta luteorubra, Coniochaeta luteoviridis and Coniochaeta mutabilis.
从一名早产儿的气管内分泌物中分离到一株新的多形拟青霉（Coniochaeta polymorpha），将其描述为一新种。该不完全真菌种的特征是：在培养 1 周后，形成深棕色的菌落；大量产生酵母样细胞和类似于厚垣孢子的结构，可产生离散的、棕色的、近球形的瓶梗状产孢细胞，不产生厚垣孢子。ITS 区、部分 LSU rDNA、肌动蛋白和β-微管蛋白基因的联合序列数据集充分解析了该种的独特系统发育地位。为了响应多形真菌命名法的最新变化，我们将 Lecythophora 种转移到 Coniochaeta 属中，并提出以下新的组合：Canina Coniochaeta、Cateniformis Coniochaeta、Decumbens Coniochaeta、Fasciculata Coniochaeta、Hoffmannii Coniochaeta、Lignicola Coniochaeta、Luteorubra Coniochaeta、Luteoviridis Coniochaeta 和 Mutabilis Coniochaeta。
