Fruit-bodies of six Thelephora species (Fungi, Basidiomycota, Thelephoraceae) were analyzed for their trace element concentrations. In Thelephora penicillata, extremely high concentrations of Cd and As were found, followed by highly elevated concentrations of Cu and Zn. The highest accumulation ability was found for Cd with a mean concentration of 1.17 ± 0.37 g kg (dry mass) in fruit-bodies collected from 20 unpolluted sites; the mean As concentration was 0.878 ± 0.242 g kg. Furthermore, striking accumulation of Se (923 ± 28 mg kg) was found in one sample of T. vialis and elevated concentrations of S were detected in T. palmata (19.6 ± 5.9 g kg). The analyzed Thelephora species were sequenced and, based on the Maximum Likelihood phylogenetic analysis (ITS rDNA) of the genus, possible other Thelephora (hyper)accumulators were predicted on the basis of their phylogenetic relationship with the discovered (hyper)accumulators. The striking ability of T. penicillata to accumulate simultaneously Cd, As, Cu, and Zn has no parallel in the Fungal Kingdom and raises the question of a biological importance of metal(loid) hyperaccumulation in mushrooms.
对六种革菌属物种（真菌，担子菌门，革菌科）的子实体进行了微量元素浓度分析。在帚状革菌中，发现镉和砷的浓度极高，其次是铜和锌的浓度大幅升高。从20个未受污染地点采集的子实体中，镉的积累能力最强，平均浓度为1.17±0.37克/千克（干质量）；砷的平均浓度为0.878±0.242克/千克。此外，在一个多育革菌样本中发现了显著的硒积累（923±28毫克/千克），在掌状革菌中检测到较高的硫浓度（19.6±5.9克/千克）。对分析的革菌属物种进行了测序，并基于该属的最大似然系统发育分析（ITS rDNA），根据它们与已发现的（超）积累者的系统发育关系，预测了可能的其他革菌属（超）积累者。帚状革菌同时积累镉、砷、铜和锌的显著能力在真菌界中无与伦比，这引发了关于蘑菇中金属（类金属）超积累的生物学重要性的问题。
