从形态特征和分子生物学证据两方面描述了采自中国西南地区的一个食用红牛肝菌新种--红牛肝菌Rubroboletus esculentus。在形态学上，本种的特征是其鲜艳的红色和有光泽的菌盖，新鲜的黄色背景，在黄色背景的菌柄上有橘红色到棕黄色的颗粒状，蓝色的颜色变化，交织的表皮pileipelis嵌入在凝胶化的基质中，光滑的孢子，分布在Quercus semecarpifolia森林中，气味芳香。基于ITS、nrLSU、tef 1-α、rpb 1和rpb 2 5个基因标记的系统发育分析表明，该类群是一个独立的新类群，与已知的Rubroboletus种不同。它的形态插图和描述提供。
A new edible species, Rubroboletus esculentus , is described from southwestern China based on both morphological characters and molecular evidence. Morphologically, this species is characterized by its vivid red and shiny pileus, fresh yellow context, orange-red to brownish yellow granulose on the yellow background of the stipe, a bluish color change, an interwoven trichodermal pileipellis embedded in a gelatinized matrix, smooth spores, a distribution in a Quercus semecarpifolia forest and a fragrant odor . Our phylogenetic analyses based on five gene markers (ITS, nrLSU, tef1-α, rpb1 and rpb2 ) proved it to be a new independent taxon, which was distinct from the known Rubroboletus species. Its morphological illustrations and descriptions are provided.
