During the fungal investigations of Larix hosts in China, ten isolates of Phaeobotryon were obtained from dead and dying branches. Morphological characteristics and phylogenetic analyses of combined ITS, LSU, and tef1-α loci revealed the presence of two new species, P. laricinum and P. longiparaphysium, as well as two new host records for P. aplosporum and P. rhois from L. olgensis. In this study, we provide descriptions and illustrations of these species, thereby enriching the diversity within the Phaeobotryon taxa.
