摘要

本文报道了虎耳虎耳属和灰耳虎耳虎耳虎耳属四新种(真菌:侧耳科)。发现于加拿大安大略省松树上的Hohenbuehelia algonquinensis,从宏观上看,可以通过其煤黑色的毛柄与蓝色的H. atrocoerulea和水样灰棕色的H. grisea区分开来。加拿大安大略省和阿尔伯塔省的松树上或与之相关的Hohenbuehelia canadensis,以及安大略省的Salix上和美国怀俄明州的冷杉上的Hohenbuehelia nimueae,都有类似的深色子实体,并且以前被错误地识别为近似H.(我们将其视为H. grisea的同义词),H. atrocoerulea, H. mustialensis或H. nigra。后一种被证明是Resupinatus的一员,尽管在其膜中存在着突出的胶质囊胞。在哥斯达黎加发现了Hohenbuehelia carlothornii;有性子实体的集合以前被鉴定为稻瘟病菌,而土壤线虫的分离物被鉴定为变形名称Nematoctonus robustus。这个名字一直被视为H. atrocoerulea的同义词,但是,考虑到这个复合体内的遗传和地理变异,我们把它作为一个独特的物种转移到Hohenbuehelia。核糖体DNA内部转录间隔区(ITS)、大亚基基因D1/D2可变区和部分翻译延伸因子(TEF1)基因的序列为这些新种提供了良好的分离和支持。提供了北美和欧洲霍恩布埃利亚(Hohenbuehelia)的近缘种的分类表。

New species of Hohenbuehelia, with comments on the Hohenbuehelia atrocoerulea - Nematoctonus robustus species complex.

Four new species of Hohenbuehelia (Fungi: Pleurotaceae) are described in the group of Hohenbuehelia atrocoerulea and Hohenbuehelia grisea. Hohenbuehelia algonquinensis, found on Pinus in Ontario, Canada, may be distinguished macroscopically from bluish collections of H. atrocoerulea and watery grey-brown collections of H. grisea by its coal-black pileus. Hohenbuehelia canadensis, on or associated with Pinus in both Ontario and Alberta, Canada, and Hohenbuehelia nimueae, on Salix in Ontario and Abies in Wyoming, USA, have similarly dark fruiting bodies and were previously misidentified as H. approximans (which we treat as a synonym of H. grisea), H. atrocoerulea, H. mustialensis or H. nigra. The latter species is shown to be a member of Resupinatus, despite the presence of prominent metuloid cystidia in its hymenium. Hohenbuehelia carlothornii has been found in Costa Rica; collections of the sexual fruiting bodies were previously identified as H. grisea and isolates from soil nematodes were identified by the anamorph name Nematoctonus robustus. That name has been treated as a synonym of H. atrocoerulea but, given the genetic and geographic variation within this complex, we transfer it to Hohenbuehelia as a distinct species. Sequences of the nuclear ribosomal DNA internal transcribed spacer region (ITS), the D1/D2 variable region of the large subunit gene, and a portion of the translation elongation factor (TEF1) gene provide good separation and support for these new species. A key to the dimidiate species of Hohenbuehelia of North America and Europe is provided.

期刊介绍: Persoonia aspires to publish papers focusing on the molecular systematics and evolution of fungi. Additionally, it seeks to advance fungal taxonomy by employing a polythetic approach to elucidate the genuine phylogeny and relationships within the kingdom Fungi. The journal is dedicated to disseminating high-quality papers that unravel both known and novel fungal taxa at the DNA level. Moreover, it endeavors to provide fresh insights into evolutionary processes and relationships. The scope of papers considered encompasses research articles, along with topical and book reviews.
