2023年, 全球2,050位学者共发表了4,372个菌物新命名, 包括7个新纲、17个新目、56个新科及新亚科、316个新属及次级属下单元、2,997个新种及种下单元, 以及831个新组合、33个修订名称和115个其他名称。这些新名称隶属于3界13门47纲170目441科1,342属, 以小型子囊菌发表的新分类单元最多。本年度发表的菌物新种采集自世界102个国家和地区, 其中亚洲东部和南部是发现新种最多的地区; 中国是发现新种最多的国家, 共发现1,249种, 占全球的41.98%。中国学者的分类学研究成果同样保持全球领先, 548位中国学者参与发表了2,160个菌物新名称, 占全球新名称总数的49.41%。我国西南和华南地区发现的新种较多, 其中云南省发现了343个菌物新种, 为国内之最。而面积广袤的西北地区和边境省份的菌物多样性研究十分匮乏, 建议加大对这些地区的投入, 这不仅有利于当地生物多样性保护和资源开发, 也是维护国家生态安全的重要保障。

Aims: Compilations of biodiversity catalogs are of great significance for biodiversity research, resource protection, and social and economic development. However, due to rapid research progress, a large number of new species and distribution records are reported every year, which requires accurate methods to summarize the discoveries of new taxa, as well as update species checklists frequently.

Method: Taxonomic data for newly published fungal names were retrieved and analyzed from the Fungal Names nomenclatural repository.

Results: In 2023, 2,050 scholars published 4,372 new fungal names throughout the world, including 7 classes, 17 orders, 56 families and subfamilies, 316 genera and subgenera, 2,997 species and intraspecific taxa, 831 combinations, 33 replacement names and 115 other names. These new names belonged to 3 kingdoms, 13 phyla, 47 classes, 170 orders, 441 families and 1,342 genera, among which micro-ascomycetes received the most attention. These newly published 2,975 fungal species were discovered from 102 countries and regions throughout the world, with eastern and southern Asia as the most noticeable spot for novel species discovery. In particular, China remained the most imminent country for annual species discoveries (1,249 species) that accounts for 41.98% of the world’s total new species. Additionally, Chinese scholars led the world in research output on fungal taxonomy in 2023, where 548 Chinese scholars participated in the publications of 2,160 new fungal names to contribute to nearly half of the world’s total new names.

Conclusion: The total number of fungal nomenclature novelties published globally this year has decreased slightly compared to last year, but it still remains fluctuating upwards in line with the general trend of previous years. Except for China, Australia, Brazil, Thailand and the United States remain in the lead, Asian countries such as India, Japan and Pakistan have become the new hot spots of fungal research instead of European countries. Since 2021, the number of new names published by Chinese scholars, and the contribution ratio to the world have broken the historically record for consecutive two years.
