is one of the most common fungal genera found indoors; it is important because it can cause a wide range of diseases in humans. species identification is based on a combination of morphological, physiological, and molecular methods. However, molecular methodologies have rarely been used for the identification of environmental isolates of in Cuba. Therefore, the objective of this work was to identify the species of the genus obtained from houses in Havana, Cuba, through the construction of phylogeny from a partial sequence of the gene region, and to analyze the diversity and richness of in the studied municipalities. Isolates of spp. included in this study presented the typical macro- and micromorphology described for the genus. According to this polyphasic characterization, , , , , , , , and were the most abundant species. Most of the identified species constitute new records for outdoor and indoor environments in Cuba and contribute to the knowledge of fungal biodiversity in the country. These results constitute an alert for the health authorities of the country, since prolonged exposure of the inhabitants to spores can cause severe persistent asthma, among other diseases.
是室内最常见的真菌属之一；它很重要，因为它能在人类中引发多种疾病。物种鉴定基于形态学、生理学和分子方法的综合运用。然而，在古巴，分子方法很少用于鉴定环境中的分离株。因此，本研究的目的是通过构建来自基因区域部分序列的系统发育树，鉴定从古巴哈瓦那房屋中获得的该属物种，并分析所研究城市中的多样性和丰富度。本研究中包含的该属分离株呈现出该属所描述的典型宏观和微观形态。根据这种多相特征，、、、、、、、和是最丰富的物种。大多数已鉴定的物种构成了古巴室外和室内环境的新记录，并有助于该国真菌生物多样性的知识积累。这些结果对该国卫生当局构成了警示，因为居民长期接触孢子会导致严重的持续性哮喘等疾病。
