Abstract

Background: Trechispora (Hydnodontaceae) comprises a diverse group of wood- and soil-inhabiting fungi, primarily functioning as saprotrophs, with some species forming symbiotic associations with plants and animals. Despite the recognition of over 100 species worldwide, its diversity in Taiwan remains understudied. This study presents the first comprehensive taxonomic revision of Trechispora in Taiwan, integrating morphological and phylogenetic analyses based on sequence data from the nuc rDNA internal transcribed spacer ITS1-5.8S-ITS2 (ITS) region and the nuc 28S rDNA (28S).

Results: We describe four new species (Trechispora acerosa, T. floralis, T. formosana, and T. orchidophila) and report seven newly recorded species for Taiwan (T. crystallina, T. dentata, T. latehypha, T. mollusca, T. odontioidea, T. subsinensis, and T. wenshanensis). T. sinensis is synonymized under T. odontioidea. Morphological and phylogenetic analyses support their taxonomic placements, and an identification key to accepted Trechispora species in Taiwan is provided.

Conclusion: This study expands the known diversity of Trechispora in Taiwan to 17 species, highlighting their ecological significance and potential interactions with plants in Taiwan's forest ecosystems.

标题台湾担子菌属（担子菌科）新种及新记录。

背景：蛭孢菌（水蛭科）是一种多样的栖息于木材和土壤中的真菌，主要功能是腐养菌，其中一些物种与植物和动物形成共生关系。尽管世界上已知的物种超过100种，但台湾的多样性仍未得到充分研究。本研究基于nuc rDNA内转录间隔区ITS1-5.8S-ITS2 （ITS）区和nuc 28S rDNA （28S）的序列数据，首次对台湾褐孢虫进行了形态学和系统发育的综合分类修订。结果：我们在台湾发现了4个新种（针叶T.、花T.、台湾T.、兰花T.）和7个新种（结晶T.、齿状T.、后菌丝T.、软体T.、齿状T.、苏sinensis、文山T.）。T. sinensis在T. odontioidea下同义。形态学和系统发育分析支持了它们的分类位置，并提供了台湾公认的褐霉属的鉴定关键。结论：本研究将台湾地区已知的树孢子虫的多样性扩大到17种，突出了它们的生态意义和与台湾森林生态系统植物的潜在相互作用。
