Ectomycorrhizas (ECM) formed by Tomentella species (Thelephorales, Basidiomycota) were collected in beech forests of Hungary and studied using anatomical and molecular phylogenetic methods. The mycobionts were identified by analysing the sequences of nuclear ribosomal DNA (nrDNA) internal transcribed spacer (ITS) regions together with sequences obtained from public databases. At the sampling plots, we found the occurrence of 11 Tomentella morphotypes. Among these, six morphotypes (four identified, Tomentella atroarenicolor, Tomentella bryophila, Tomentella lapida, Tomentella subclavigera, and two unidentified) were morpho-anatomically characterized for the first time. Although the six morphotypes differed anatomically from each other and from Tomentella ectomycorrhizas described previously, they shared anatomical features common to tomentelloid ectomycorrhizas fungi. These results expand our understanding of the diversity of this widely distributed ectomycorrhizal genus.
由绒盖牛肝菌属（多孔菌目，担子菌门）物种形成的外生菌根在匈牙利的山毛榉林中被采集，并使用解剖学和分子系统发育方法进行研究。通过分析核糖体DNA（nrDNA）内部转录间隔区（ITS）区域的序列以及从公共数据库获得的序列来鉴定菌根真菌。在采样地，我们发现了11种绒盖牛肝菌形态型。其中，六种形态型（四种已鉴定，即黑褐绒盖牛肝菌、苔藓绒盖牛肝菌、石生绒盖牛肝菌、近棒绒盖牛肝菌，以及两种未鉴定的）首次在形态解剖学上进行了特征描述。尽管这六种形态型在解剖学上彼此不同，也与先前描述的绒盖牛肝菌外生菌根不同，但它们具有绒盖牛肝菌类外生菌根真菌共有的解剖学特征。这些结果扩展了我们对这个广泛分布的外生菌根属多样性的理解。
