摘要
灰树花是中国具有较高食药用价值的大型真菌,国内外学界过去多认定其学名为 Grifola frondosa.本研究结合形态学和多基因分子系统发育分析,对分离自东亚、欧洲和北美洲的 45 份样本进行分类研究.多基因联合分析的研究显示了对应各大洲灰树花菌种的高支持率分支,表明不同地域灰树花的遗传信息存在一定程度的差异,分离自我国的灰树花菌种均属于东亚分支,欧洲和北美分支的成员在中国尚未发现分布.因此,东亚分支应代表了一个独立的物种.东亚地区的灰树花过去在日本曾经被描述为白树花G.albicans,而且该种曾经被认为是欧洲灰树花G.frondosa的同物异名,因此,东亚分支的物种学名应该是白树花G.albicans.由于中国多数野生和栽培灰树花菌盖颜色较深,故将其命名为白树花的一个新变型G.albicans f.huishuhua,并指定了该变型的模式标本和菌种(凭证标本HBAU15778,凭证菌株HBAU LM502).
Abstract
Huishuhua(maitake)is a macrofungus with high edible and medicinal values in China.It was commonly recognized as Grifola frondosa.A total of 45 huishuhua samples from East Asia,Europe and North America was analyzed on the basis of morphological and multi-gene phylogenetic methods.The results showed that highly supported clades of huishuhua samples were corresponding to each continent,indicating that genetic differences existed to a certain extent among strains from different regions.All huishuhua strains isolated from China nested in the East Asian clade.The European and North American clade members are not yet found in China.The East Asian huishuhua was described in Japan as G.albicans,and this has been once regarded as a synonym of G.frondosa.Because most wild and cultivated huishuhua in China has dark-colored pileus,a new form G.albicans f.huishuhua is thereby proposed.Holotype specimen and extype strain of this form are designated(voucher specimen HBAU15778,voucher strain HBAU LM502).
