ABSTRACT Imleria is a small genus of Boletaceae found primarily in the Northern Hemisphere characterized by the light to dark brown hymenophore that stains blue. In Florida, specimens of Imleria were collected that resembled I. badia, a species known primarily from northeastern North America and Europe. Five nuclear loci of these Florida specimens were sequenced and phylogenetically analyzed. A nuc rDNA internal transcribed spacer ITS1-5.8S-ITS2 (ITS) phylogeny of Imleria was generated using primarily uncultured environmental sequences to confirm ectomycorrhizal associations. Based on morphological and molecular data, we describe a new species, Imleria floridana. Results from these analyses also support the new combination Imleria pallida. A lectotype of I. pallida is also established from Charles H. Peck’s original material. We discuss the distinguishing characters and species of Imleria found in North America and provide a key to the known worldwide species of Imleria.

摘要 Imleria 是牛肝菌科的一个小属，主要在北半球发现，其特征是浅棕色至深棕色的膜细胞，染成蓝色。在佛罗里达州，收集了类似于 I.badia 的 Imleria 标本，该物种主要来自北美东北部和欧洲。对这些佛罗里达标本的五个核位点进行了测序和系统发育分析。使用主要未培养的环境序列来确认外生菌根关联，产生了 Imleria 的 nuc rDNA 内部转录间隔区 ITS1-5.8S-ITS2 (ITS) 系统发育。基于形态学和分子数据，我们描述了一个新物种 Imleria floridana。这些分析的结果也支持新组合 Imleria pallida。I. pallida 的选型也是从 Charles H. Peck 的原始材料中建立的。
