元宵湿伞,湿伞属一新种OA
A new species of the genus Hygrocybe(Agaricales,Basidiomycota)
湿伞属是具有重要生态意义且十分引人注目的大型真菌类群.然而,该属食用菌的正式记载较为稀少.本文调查研究了江西上饶地区元宵节前后发生的一种野生食用菌,俗称"元宵菇""竹菇"或"红菇",其鲜品价格高达 1 000 元/kg.经形态学和分子系统学研究证明该物种为一个湿伞属新物种,命名为元宵湿伞Hygrocybe yuanxiaogu.该真菌的主要特征为菌盖红色至黄色、不黏或湿时微黏,担孢子(7.0)7.5-9.5×4.0-5.5 μm;子实体常生长于竹林中,在当地仅元宵节前后出现.基于 ITS 序列的系统发育分析显示,该种隶属湿伞属的红湿伞复合群Hygrocybe punicea-complex,与已知物种存在明显区别.新种的发现丰富了中国南方湿伞属已知物种的多样性,也为该属的可食用野生菌资源提供了新实例.
The genus Hygrocybe is an ecologically significant and morphologically attractive fungal group.However,the formal records of edible species within this genus remain relatively scarce.This study investigates a wild edible fungus fruiting around the Lantern Festival in Shangrao,Jiangxi Province,with fresh products selling for up to 1 000 CNY per kilogram.It is locally known as"yuanxiaogu"(Lantern Festival mushroom),"zhugu"(bamboo mushroom)or"honggu"(red mushroom).Further study confirms that this taxon is a new Hygrocybe species,and named as Hygrocybe yuanxiaogu.This fungus has red-to-yellow,non-viscid or slightly viscid pileus when wet,with basidiospores measuring(7.0)7.5-9.5×4.0-5.5 μm.The fungus grows in bamboo forests,and fruits around the Lantern Festival in the local area.Phylogenetic analysis based on ITS sequences shows that this new species belongs to the Hygrocybe punicea-complex and is distinct from all known Hygrocybe species.This species is mainly distributed in southern China,providing new example of edible wild fungal resources within this genus.
