全寄生是显花植物特有的生活史。所有的碳源都由光合宿主植物提供。最近的一项研究揭示了内生真菌在全寄生植物中的存在，但它们的生态和进化作用仍然未知。在这项研究中，我们研究了内生真菌分离的全寄生植物蛇菰（蛇菰科），收集从高知，四国在日本西部。从3个B的花序和块茎上分离到23个真菌菌株。日本植物在两个位置和一个样品的宿主植物（山矾，山矾科）。优势菌株为木霉-肉座菌属、青霉属和瓶霉属。第一组在寄主植物中也占优势。本研究中揭示的真菌组成与B上的组成不同。harlandii或其它根全寄生物与内生真菌（Rafflesia cantleyi）数据。这些差异可能是由多种因素引起的，包括生长习性、地理位置、系统发育位置或寄主-寄生物关系。
Holoparasitism is a special life cycle of flowering plants. All carbon resources are provided by photosynthetic host plants. A recent study revealed the presence of endophytic fungi in holoparasitic plants, but their ecological and evolutionary roles are still unknown. In this study, we examined endophytic fungi isolated from the holoparasitic plant Balanophora japonica (Balanophoraceae), collected from Kochi, Shikoku in western Japan. We isolated 23 fungal strains on inflorescences and tubers from three B. japonica plants at two locations and on one sample of the host plant (Symplocos lancifolia, Symplocaceae). Predominant isolates were Trichoderma-Hypocrea, Penicillium and Phialemonium. The first group was also predominant in the host plant. Fungal composition revealed in this study differed from the composition on B. harlandii or other root holoparasites with endophytic fungal (Rafflesia cantleyi) data. Those differences might be caused by various factors, including growth habits, location, phylogenetic position or host-parasite relationship.
