Background Aquatic hyphomycetes are a phylogenetically heterogeneous group of fungi living preferentially in fast flowing, well-aerated forest streams. These fungi have worldwide distribution, but with the exception of Articulospora tetracladia, no aquatic hyphomycete taxon was previously recorded on Madeira Island. Aquatic hyphomycetes were sampled from 40 sites, distributed by 27 permanent streams in 2015, to provide the distribution of aquatic hyphomycetes in Madeira Island streams. New information In this study, a total of 21 species of aquatic hyphomycetes were recorded belonging to three classes of Ascomycota. All taxa are new records for Madeira Archipelago, except Articulospora tetracladia and four are reported for the first time in Macaronesian biogeographic region.

马德拉岛（葡萄牙）溪流中的水生丝菌。


背景水生丝菌是一类系统发育异质的真菌，优先生活在水流湍急、通风良好的森林溪流中。这些真菌在世界范围内都有分布，但除了四孢节孢菌（Articulospora tetracladia）之外，以前在马德拉岛上没有记录到水生丝孢菌类群。 2015 年，对 27 条永久性溪流分布的 40 个地点的水生丝菌进行了采样，以提供马德拉岛溪流中水生丝菌的分布情况。新信息 在这项研究中，总共记录了 21 种水生丝菌，属于子囊菌门的三个纲。除Articulospora tetracladia 外，所有类群均为马德拉群岛新记录，其中4 个类群为马卡罗尼西亚生物地理区首次报道。
