摘要

真菌的多样性正在迅速扩大，世界各地不断发现新的物种。泰国北部被认为是真菌多样性的热点地区。在这项研究中，我们从泰国清迈府的腐朽木材中采集了一种吸液微真菌。利用最大似然法和贝叶斯推断法对ITS、LSU和SSU序列进行了形态学检查和系统发生学分析，将新分离物归入Kirschsteiniothelia。Kirschsteiniothelia chiangmaiensis sp.nov.的特征是有 8 个 spored、圆柱状棍棒状的无精子，有一个小的眼室和 1 septate ascospores，这些 ascospores 为椭圆形至纺锤形，有明显的肠管和被粘液鞘包围的光滑壁。Kirschsteiniothelia chiangmaiensis 与模式标本的不同之处在于有较小的子囊、较宽的子囊腔和多栉孔，与 K. thujina 的不同之处在于有较小的子囊、子囊孢子和粘液鞘。根据形态学和系统发育证据，我们将 K. chiangmaiensis 列为一个新种。

A new addition to Kirschsteiniotheliaceae: Kirschsteiniothelia chiangmaiensis sp. nov. from Northern Thailand

Fungal diversity is rapidly expanding, with new species being discovered worldwide. Northern Thailand is considered a hotspot for fungal diversity. In this study, we collected a saprobic microfungus from decaying wood in Chiang Mai Province, Thailand. Morphological examination and phylogenetic analyses of ITS, LSU, and SSU sequences using maximum likelihood and Bayesian inference placed a new isolate within Kirschsteiniothelia. Kirschsteiniothelia chiangmaiensis sp. nov. is characterised by 8-spored, cylindrical-clavate asci with a small ocular chamber and 1-septate ascospores that are ellipsoid to fusiform, with distinct guttules and a smooth wall surrounded by a mucilaginous sheath. Kirschsteiniothelia chiangmaiensis differs from the type by the smaller ascomata, wider asci, and presence of pluri-guttulate, and diverges from K. thujina by smaller ascomata, ascospore, and the presence of mucilaginous sheath. Based on morphology and phylogeny evidence, we introduce K. chiangmaiensis as a new species.

期刊介绍： Phytotaxa is a peer-reviewed, international journal for rapid publication of high quality papers on any aspect of systematic and taxonomic botany, with a preference for large taxonomic works such as monographs, floras, revisions and evolutionary studies and descriptions of new taxa. Phytotaxa covers all groups covered by the International Code of Nomenclature foralgae, fungi, and plants ICNafp (fungi, lichens, algae, diatoms, mosses, liverworts, hornworts, and vascular plants), both living and fossil. Phytotaxa was founded in 2009 as botanical sister journal to Zootaxa. It has a large editorial board, who are running this journal on a voluntary basis, and it is published by Magnolia Press (Auckland , New Zealand). It is also indexed by SCIE, JCR and Biosis. All types of taxonomic, floristic and phytogeographic papers are considered, including theoretical papers and methodology, systematics and phylogeny, monographs, revisions and reviews, catalogues, biographies and bibliographies, history of botanical explorations, identification guides, floras, analyses of characters, phylogenetic studies and phytogeography, descriptions of taxa, typification and nomenclatural papers. Monographs and other long manuscripts (of 60 printed pages or more) can be published as books, which will receive an ISBN number as well as being part of the Phytotaxa series.
