Abstract
Gibellulopsis chrysanthemi sp. nov. is described and illustrated from specimens on rotten leaves of garland chrysanthemum (Chrysanthemum coronarium L. var. spatiosum L.H. Bailey), collected in three different sites of Osaka Prefecture, Japan. This species is characterized by having short and long verticillium-like conidiophores, 1-septate, long-cylindrical conidia with tapering ends and slightly brownish chlamydospores. Compared morphologically with other species in the Plectosphaerellaceae (sister to the Glomerellales), G. chrysanthemi is similar to Gibellulopsis nigrescens, from which it differs in the formation of long conidiophores and 1-septate, long-cylindrical conidia with tapering ends. In addition, the molecular analyses of G. chrysanthemi and other members of the Plectosphaerellaceae based on a phylogenetic tree with three-loci (ITS, D1/D2, tef1-α) sequences reveal that G. chrysanthemi is located as a sister group of G. nigrescens.
