元宵湿伞,湿伞属一新种
A new species of the genus Hygrocybe(Agaricales,Basidiomycota)
摘要
Abstract
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.关键词
