Six strains of black meristematic fungi were isolated from Antarctic soils, gasoline car tanks and from the marine alga . These fungi were characterized by morphological, physiological and phylogenetic analyses. According to the maximum-likelihood analysis reconstructed with ITS and LSU sequences, these strains belonged to the genus sp. nov. (holotype CBS 148926) and sp. nov. (holotype CBS 149015) are proposed as two novel species and descriptions of their morphological, physiological and phylogenetic features are presented. Based on the maximum-likelihood analyses, was closely related to (99 % bootstrap support), while clustered in the clade of and (93 % bootstrap support). , recorded in Antarctic soil samples, had a psychrophilic behaviour, with optimal growth between 10 and 15 °C and no growth recorded at 20 °C. , from a gasoline car tank and algae, displayed optimal growth between 20 and 25 °C and was more tolerant to salinity than .
从南极土壤、汽油汽车油箱和海洋藻类中分离出六株黑色分生组织真菌。通过形态学、生理学和系统发育分析对这些真菌进行了表征。根据用ITS和LSU序列重建的最大似然分析，这些菌株属于 属 新种（模式菌株CBS 148926）和 属 新种（模式菌株CBS 149015），被提议为两个新物种，并对其形态、生理和系统发育特征进行了描述。基于最大似然分析， 与 密切相关（99%的自展支持率），而 聚集在 和 的分支中（93%的自展支持率）。记录于南极土壤样本中的 在10至15°C之间生长最佳，在20°C时无生长记录，具有嗜冷行为。来自汽油汽车油箱和藻类的 在20至25°C之间生长最佳，并且比 更耐盐。
