Nematode-trapping fungi are widely studied due to their unique morphological structure, survival strategy, and potential value in the biological control of harmful nematodes. During the identification of carnivorous fungi preserved in our laboratory, five novel nematode-trapping fungi were established and placed in the genera and based on morphological and multigene (, , and ) phylogenetic analyses. sp. nov. and sp. nov. are characterized by producing adhesive networks to catch nematodes. sp. nov., sp. nov., and sp. nov. are characterized by producing constricting rings. Morphological descriptions, illustrations, taxonomic notes, and phylogenetic analysis are provided for all new taxa; a key for species is listed; and some deficiencies in the taxonomy and evolution study of nematode-trapping fungi are also discussed herein.
捕食线虫真菌因其独特的形态结构、生存策略以及在有害线虫生物防治中的潜在价值而受到广泛研究。在对本实验室保存的食肉真菌进行鉴定的过程中,基于形态学和多基因(ITS、LSU和tef1)系统发育分析,确定了5种新型捕食线虫真菌,并将它们归入相应的属。新种Acaulopage sp. nov.和Arthrobotrys sp. nov.的特征是产生粘性网络来捕获线虫。新种Dactylellina sp. nov.、Dactylium sp. nov.和Monacrosporium sp. nov.的特征是产生收缩环。本文提供了所有新分类单元的形态描述、插图、分类注释和系统发育分析;列出了Acaulopage属物种的检索表;并讨论了捕食线虫真菌在分类学和进化研究中的一些不足之处。
