Abstract
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.
