摘要：
Laccaria fagacicola and L. pallidorosea, two new species collected from subtropical broad-leaved forests, were described in this study with both molecular and morphological evidence. Laccaria fagacicola is characterized by its brownish orange basidioma and globose to subglobose, echinulate basidiospores with spines 1-2 mu m long and 1-1.5 mu m wide at base. Laccaria pallidorosea has a small and pinkish basidioma, and globose to subglobose, echinate basidiospores with spines 1.5-2 mu m long and 2 mu m wide at base. Phylogenetic analyses based on internal transcribed spacer (ITS) region indicated that L. fagacicola is sister to L. rubroalba and L. aurantia, while L. pallidorosea is related to L. versiforma and L. salmonicolor. These two new species are described, illustrated, and compared with closely related and morphologically similar species.
