Abstract

Background: Two hyphomycetous species were collected from leaves of Smilax china (Liliales, Smilacaceae) and Cremastra appendiculata (Asparagales, Orchidaceae). ITS barcoding indicated that they belong to the genus Zasmidium.

New information: Morphological data in combination with molecular phylogenetic analyses based on ITS, LSU and rpb2 confirmed that our Chinese strains represented a new species, Zasmidium liboense and a new record of Z. citri-griseum.

Keywords: Dothideomycetes; Mycosphaerellaceae; asexual morph; one new species; taxonomy.
