The genus Hebeloma has a number of species highly specific to Cistus and others that occur with several host genera. This paper discusses the species of Hebeloma that appear to be ectomycorrhizal with Cistus, judging from their occurrence when Cistus is the only available host. The previously unknown species H. plesiocistum spec. nov. is described. We also provide a key to the known Hebeloma associates of Cistus. Molecular analyses based on ITS sequence data further illustrate the distinctness of the newly described species and difficulties in the species delimitation with view to H. erumpens. Specific associations with Cistus may have evolved more than once within the genus Hebeloma.
Hebeloma属有许多物种对岩蔷薇具有高度特异性，还有其他一些物种与多个寄主属共生。本文讨论了从其在岩蔷薇为唯一可用寄主时的出现情况判断，似乎与岩蔷薇形成外生菌根的Hebeloma物种。描述了此前未知的近岩蔷薇Hebeloma plesiocistum新物种。我们还提供了已知的与岩蔷薇共生的Hebeloma物种的检索表。基于ITS序列数据的分子分析进一步说明了新描述物种的独特性以及在区分近裂褶Hebeloma erumpens时的困难。在Hebeloma属内，与岩蔷薇的特定共生关系可能不止一次地进化。
