Lactarius is one of the larger genera of ectomycorrhizal Basidiomycota, with about 400 species recognized worldwide. The ectomycorrhizae formed by Lactarius tesquorum on Cistus sp., one of the most common and ecologically relevant shrubs in the semi-arid regions in the Mediterranean basin, are described here in terms of morphological, anatomical and molecular features. An ITS rDNA sequence-based phylogenetic analysis was performed on the related European Lactarius taxa (L. mairei, L. pubescens, L. scoticus, L. spinosulus, L. torminosulus and L. torminosus) currently classified together with L. tesquorum in the subgenus Piperites section Piperites. Piperites s.s. could be divided into two main clusters; L. mairei and especially L. spinosulus were related less closely to the other taxa. This study is part of a broader effort to extend our knowledge of the distribution, phylogeny and ectomycorrhizal biology of Lactarius species in selected ecosystems.
乳菇属是外生菌根担子菌纲中较大的一个属，全世界约有 400 种。乳菇属的菌根与在半干旱地中海地区最常见和生态上最相关的灌木之一的滨藜属形成外生菌根。本文从形态、解剖和分子特征方面对其进行了描述。对相关的欧洲乳菇属分类群（L. mairei、L. pubescens、L. scoticus、L. spinosulus、L. torminosulus 和 L. torminosus）进行了基于 ITS rDNA 序列的系统发育分析，目前这些分类群与乳菇属的 Piperites 亚属 Piperites 节一起分类。Piperites s.s.可分为两个主要聚类；L. mairei 特别是 L. spinosulus 与其他分类群的关系不太密切。本研究是扩大对乳菇属在选定生态系统中的分布、系统发育和外生菌根生物学认识的更广泛努力的一部分。
