摘要
南岭是全国生物多样性热点地区之一,是广东省生物资源宝库,大型真菌资源也较为丰富。牛肝菌是大型真菌中的一个重要类群,具有重要的生态、经济和科研价值。本研究基于形态学和分子系统学研究手段,对南岭地区牛肝菌物种多样性进行了研究,明确南岭地区分布牛肝菌79种,隶属于3科31属,发现牛肝菌新种1个,南岭地区新记录种37个;排除早期错误鉴定物种28个,数据不足或存在疑问物种25个,对排除或存疑物种进行了说明。对发现的新种红褐赭黄牛肝菌Suillellu srufobrunneus进行了形态学描述与相似物种讨论。研究标本保藏在广东省科学院微生物研究所真菌标本馆(GDGM)。
Nanling is one of the hotspots of biodiversity in China,and is the treasure house of biological resources in Guangdong Province of southern China.Boletes are the important group of macrofungi,having important ecological,economic and scientific values.The species diversity of Boletales in Nanling mountainous area was investigated based on morphological characters and molecular evidences.In total,79 species were identified,belonging to 3 families and 31 genera,including one new species and 37 newly recorded species in Nanling.Twenty-eight taxa were found to be misidentified previously,and 25 previously reported species were dubious because of insufficient data.In the present paper,the species list of Boletales in Nanling Mountains was provided,and annotations of the excluded or suspected species were given.A phylogentic tree of nrLSU of boletes in Nanling was also provided.The new species,Suillellus rufobrunneus,is characterized by its red to dark purplish-red pileus,smooth,red to dark purplish-red stipe with yellow apical part and longitudinal slight reticula,and elliptical basidiospores measuring 11–15×5.5–7μm.The examined specimens were deposited in the Fungarium of Guangdong Institute of Microbiology,Guangdong Academy of Sciences(GDGM).
