Abstract

A new luminescent lignicolous fungal species, Mycena cristinae sp. nov., is proposed from the Central Amazon forest. This is unique and supported by morphological evaluation along with LSU- and ITS-based phylogenetic analyses. The basidiomata have mostly fuscous olivaceous brown pileus, adnate to subdecurrent and distant lamellae, and stipe with slightly bulbous base (basal mycelium absent). It also has inamyloid and/or weakly amyloid basidiospores, ramose cheilocystidia and a pileipellis composed of an aerated tangle of slender, diverticulate hyphae forming a coralloid pellicle overlaying the hypodermium. The luminescence is evident in the basidiomata (especially the stipe) and in the mycelium on the substrate. The LSU phylogenetic trees reveal that M. cristinae is sister to M. coralliformis within the Mycenaceae clade. In the ITS trees, it forms a unique lineage grouping with undetermined Mycena taxa. Morphological data support M. cristinae as a different species compared to previously described taxa.

产自巴西的亚马逊地区发光的Mycena cristinae sp.十一月。

在亚马逊中部森林中发现了一种新的发光木质素真菌Mycena cristinae sp. nov.。这是独特的，并支持形态评价以及LSU和its为基础的系统发育分析。担子瘤大部分有暗色橄榄色的褐色菌毛，贴生于下延和远处的片层，茎柱基部有稍球茎(无基生菌丝)。它也有淀粉样和/或弱淀粉样担子孢子、分枝囊泡和由细长的憩室状菌丝组成的透气性缠结组成的绒毛，形成覆盖在表皮上的珊瑚状膜。在担子瘤(尤其是柱头)和底物上的菌丝体中，发光是明显的。LSU系统发育树显示，M. cristinae是Mycenaceae分支中M. coralliformis的姐妹。在ITS树中，它与未确定的迈锡纳分类群形成了一个独特的谱系分组。形态学资料支持M. cristinae是不同于先前描述的分类群的物种。

期刊介绍： Mycoscience is the official English-language journal of the Mycological Society of Japan and is issued bimonthly. Mycoscience publishes original research articles and reviews on various topics related to fungi including yeasts and other organisms that have traditionally been studied by mycologists. The research areas covered by Mycoscience extend from such purely scientific fields as systematics, evolution, phylogeny, morphology, ecology, physiology, biochemistry, genetics, and molecular biology, to agricultural, medical, and industrial applications. New and improved applications of well-established mycological techniques and methods are also covered.
