Molecular phylogenetic studies were carried out based on ITS-5.8S rDNA, the D1-D2 region of the large subunit rRNA gene, RPB2, and combined data of D1-D2 and RPB2 as well as these three genes on 36 species among 7 genera for Lachnum and allied genera in the family Hyaloscyphaceae. In the combined data of all three regions, seven strongly supported clades were obtained. The same clades were also recognized in most of the trees based on each gene, and the combined data of D1-D2 and RPB2, although some of them were not strongly supported. Four clades represented Albotricha, Brunnipila, Incrucipulum, and Lachnellula, respectively, whereas Lachnum was distributed to the remaining three clades. The molecular phylogenies strongly supported a group of species with granulate hairs, and we suggest the concept of Lachnaceae should be restricted to these species. Based on the molecular phylogenetic analysis, three new combinations-Incrucipulum longispineum, I. radiatum, and Lachnellula pulverulentum from Lachnum-are proposed.
