The Orchidaceae family is a diverse family of flowering plants that occur naturally in most parts of the world. However, fungal communities inhabiting different parts of orchids are not sufficiently described. The aim of the study was to conduct a mycological evaluation of Epipactis helleborine and E. purpurata (Orchidaceae), which grow naturally in Lower Silesia (SW Poland), by identifying the species composition of the culturable micromycetes fungi on the surfaces of the plants and from the inner layers of the tissues. Fungi were identified based on a phenotypic and genotypic analysis. To our knowledge, this is the first such analysis. This study showed that more species of micromycetes were cultured from E. helleborine compared with E. purpurata. The flowering plants of E. helleborine were inhabited by the largest number of culturable fungal species (13 species), and the fewest species were isolated from the flowering plants of E. purpurata (eight species). Some of these fungal species may be pathogens of the plants. The surface tissues of the orchids were mainly inhabited by Mucor moelleri and/or Penicillium biourgeianum. The inner layers of these plants were the most colonized by Alternaria tenuissima and/or Arthrinium arundinis and/or Fusarium sporotrichioides. The relative dominance of these fungal species depended mainly on the development phase of the plants.

波兰西南部与Epipactis helleborine和Epipactis purpurata（兰科，Neottieae）相关的微真菌的物种多样性

兰科科是世界上大部分地区天然存在的多种开花植物科。但是，关于兰花不同部分的真菌群落的描述却不够。该研究的目的是通过鉴定植物和植物表面上可培养的微真菌真菌的物种组成，对在下西里西亚（波兰）自然生长的Epipactis helleborine和E. purpurata（兰科）进行真菌学评估。从组织的内层。根据表型和基因型分析鉴定真菌。就我们所知，这是第一个这样的分析。这项研究表明，micromycetes更多种源自培养E. helleborine相比E. purpurata。黑斑海肠草的开花植物居住着最多数量的可培养真菌物种（13种），而从紫罗兰海胆的开花植物中分离的物种最少（八种）。这些真菌物种中的某些可能是植物的病原体。兰花的表面组织主要居住在Mocor moelleri和/或Biurgillium biourgeianum中。这些植物的内层最容易被链格孢菌（Alternaria tenuissima）和/或青蒿（Arthrinium arundinis）和/或镰孢镰刀菌（Fusarium sporotrichioides）定植。这些真菌物种的相对优势主要取决于植物的发育阶段。
