Abstract

Nothophoma as a phoma-related genus comprises plant pathogens, endophytes and saprobes with several hosts. In this study, three fresh strains were isolated from Spiraea salicifolia in Beijing, China. Both morphological observation and multi-locus phylogenetic analyses (ITS, LSU, rpb2 and tub2) suggest the position of the new species in Nothophoma, which forms a monophyletic lineage with strong support. Nothophoma spiraeae sp. nov. is characterized by having dense and fluffy colony, producing abundant pycnidia with aseptate conidia, and differs from its relatives in sequence data and by host association.
